  1. This post is designed to give a basic overview of modern Toyota Diesel engines and their commonly troublesome components: How does a Diesel engine work? Firstly Diesel is not as flammable as Petrol. Diesel engines don’t have spark plugs to ignite the fuel, but to bring about combustion they require heat. If you put your finger over the end of a foot pump and pump it, your finger will become hot. This is due to compression of the air trapped inside the pump (the air molecules have less space to move about and collide with each other more frequently causing energy to be given off in the form of heat). The same thing happens in a diesel engine: as the piston moves upwards, the air trapped inside is compressed, causing it to heat up (the temperature reached is circa 400 degrees C). Just before the piston reaches the top of its' stroke, the pump and injectors spray a very fine mist of diesel into the piston chamber. The intense heat of the trapped air in the piston causes the diesel to ignite, forcing the piston down and producing the power stroke which goes through the engine via the gearbox / wheels etc etc and off you go. What are Glow Plugs? When internal sensors detect that the core of the engine block has reached a certain designated temperature, or when a certain amount of time elapses, the glowplug relay switches off the "wait-to-start" light. A pre-heating cycle usually lasts for 2 to 5 seconds. The driver then turns the key to the "start" position. The glowplug relay switches off the glowplugs after the engine is running. In some newer cars, glow plugs continue to operate for up to 180 seconds after engine start to keep the engine within emissions regulations, as combustion efficiency is greatly reduced when the engine is very cold. Link http://en.wikipedia.org/wiki/Glowplug As glow plugs wear out the vehicle will be more difficult to start, run poorly and produce a white/bluey smoke. Glow Plugs are a reasonably cheap to replace. What is D4D? D4D is Toyota’s version of Common Rail Diesel. The term "common rail" refers to the fact that all of the fuel injectors are supplied by a common fuel rail which is nothing more than a pressure accumulator where the fuel is stored at high pressure. This accumulator supplies multiple fuel injectors with high pressure fuel. Modern common rail systems, are governed by an engine control unit (ECU) which opens each injector electronically rather than mechanically. What are Injectors? Fuel injectors are a key part of modern automotive systems, as they're responsible for getting fuel into the engine in a precise, orderly and carefully engineered pattern. Unfortunately, the conditions we drive in are not ideal. Pollution is in the air, and fuel can be contaminated with water, dirt particles and other debris. Regularly changing your fuel filter (according to change interval in your service book) will help keep debris from circulating. You can also add fuel injector cleaner to your fuel tank, which may help solve running issues. Doing this at regular intervals of 10,000 miles or so might provide more cleansing than your engine actually needs, but it shouldn’t harm the system. Injector Cleaner can't improve your car beyond its original factory spec. When injectors fail there are generally two approaches to repair, take the vehicle to a main dealer and have the whole set (£1000+) replaced or find a diesel specialist who may be able to replace or repair individual injectors (circa £250 each) after testing. Fuel Injector problem symptoms include, poor starting, rough running, loss of power, black or white smoke. It is generally known that injectors will need attention after 100,000 miles. What is a Turbo? Turbochargers are a type of forced induction system. They compress the air flowing into the engine. The advantage of compressing the air is that it lets the engine squeeze more air into a cylinder, and more air means that more fuel can be added. Therefore, you get more power from each explosion in each cylinder. A turbocharged engine produces more power overall than the same engine without the turbocharging. When Turbo’s are failing they will typically cause the car to have a loss of power, excessive smoke and in some cases a high pitched whine. Turbo’s can often be repaired bya turbo specialists or replaced with a new unit, obviously a repair is cheaper. What is an SCV? SCV's (Suction Control Valves) are used in Common Rail diesel engines to control the pressure of the fuel in the accumulator. The pressure is varied by the ECU by controlling how much fuel the pump feeds into the accumulator, replacing the fuel as it is delivered into the engine by the injectors. Low pressure for the injectors at idle, high pressure at maximum power. Electrically operated, SCVs can need to open and close at up to 200 times per second and if they stick or fail to open properly then poor running, starting and power loss can occur. Sticking when hot is often cited as a cause of hot starting problems. D4D pumps may have one or two of these valves depending on the type of pump fitted, this is important when ordering the correct parts. Vehicles commonly affected by this have the 1CD-FTV 2.0 D4D Engine 2000-2005, found on RAV4/Avensis/Corolla built between these dates. This article SCV's on the RAV4 Forum provides an overview of the location and parts on a two valve pump. These parts are typically £250 to replace + fitting if required. What is an EGR Valve? Exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in modern engines, EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. After a while the gases containing dirty, sooty carbons start to cover and coat the intake area and valves causing the air to fuel ratio to become unbalanced thus resulting in more black smoke being emitted from the exhaust. This black smoke is then drawn back into the air intake via the EGR valve. A vicious cycle then starts with the engine producing more smoke and sootier carbons being drawn into the intake, a major problem. Symptoms of EGR issues include lack of power, engine hesitancy and then a surge of power followed by black sooty smoke. A fall in fuel economy may also occur. On most Toyota engines the valve is easily removed and cleaned, a dealer will charge an hours labour to do the same job. If the valve fails it will cost around £300 to be supplied and fitted by Mr T. If the vehicle is used continually then carbon clogging could eventually lead to head gasket failure on AD engines, please review the attached document to see if your car has one of these engines.AD Head Gaskets.pdf A simple method of trying to keep the EGR valve clean is to drive the vehicle (once warm) hard by bringing the revs near to the red line, this will result in black soot leaving the exhaust, continue this until the soot no longer appears. This should be a weekly event. This is also known as an Italian Tune Up. Personally as my 2.2 D4D Verso is out of warranty i clean the EGR every 10k, this a superb guide http://www.toyotaown...howtopic=106241 What is D-Cat? D-CAT (Diesel Clean Advanced Technology) is Toyota’s version of a diesel particulate filter (DPF) which is a device designed to remove soot from the exhaust gas of a diesel engine. The soot created by the engine is burnt off during the regeneration process, this process uses fuel which is added by an additional injector, this additional fuel usage reduces MPG when compared with vehicles that dont have a DPF. The regeneration process occurs at road speeds higher than can generally be attained during urban usage ,vehicles driven exclusively at low speeds in urban traffic will require periodic trips at higher speeds to clean out the DPF. On cars with a very high sixth gear the engine revs may be too low to generate sufficient exhaust temperature for regeneration. Occasional harder driving in lower gears should be sufficient to burn off the soot in such cases. With this type of DPF regeneration will be initiated by the ECU every 300 miles or so depending on vehicle use and will take 10 to 15 minutes at 40MPH+ to complete. You shouldn't notice anything other than perhaps a puff of white smoke from the exhaust when the process is completed. If the DPF doesn’t regenerate properly eventually a warning light will be displayed and the vehicle should be taken to a main dealer. Continued usage past this point may destroy the DPF completely so it must be replaced, this will be very expensive (£1000+). DPF Continued If your car is type approved and registered after the date below it will have a DPF to meet the EU Emissions, things can get very complicated here. Vehicles are often built long before being registered, so you could purchase a 2010 car that was a 2009 model. Its important to ask what model year your car is and which emission standard it meets. Its possible to be driving a 10/60 or even an 11 Reg thats not Euro 5 (V) if the car was built long before being registered. Euro 5 (V) Emissions Standard Commenced - September 2009 If you only drive low mileages in town do not buy a Diesel with a DPF. A Petrol is more suitable. Modern Diesels are very complex machines, following manufacturer servicing guidelines is essential as is using the correct oils, fluids and drivers checking levels frequently. The issues mentioned above are not restricted to Toyota's, all manufacturers have these issues and probably more of them. Hopefully this is useful to people Please PM me if any of this requires amending.
  2. I had a year and 40k in a 11' plate 2.0 D4D TR Tourer, i agree with handbrake, really bad design compared to the Passat i had before with its auto function. Except for lacking a bit of power they are a quiet and comfy solid motor, good value as well. I went to Rome and back in her , had my Tom Tom as well....
  3. Bump Relisted due to time wasters - http://www.ebay.co.uk/itm/4x-205-55-16-Avon-Winter-Tyres-Steel-Wheels-Toyota-Prius-Avensis-/191746238754?fits=Model%3AAvensis&hash=item2ca4f76922:g:VhkAAOSw14xWNhBT I am looking for £200, but as its an auction who knows where it will end!
  4. Hi All, I have these on Ebay at the moment, they are a straight fit onto a T25 Avensis 03-08, they have come from my 2011 Prius which has been sold on. The wheels are in good condition and the tyres have covered around 4,000 miles ONLY over 2 winter seasons. http://www.ebay.co.uk/itm/4x-205-55-16-Avon-Winter-Tyres-Steel-Wheels-Toyota-Prius-Avensis-/191746238754?fits=Model%3AAvensis&hash=item2ca4f76922:g:VhkAAOSw14xWNhBT They wont fit the T27, but will fit the T22. I am looking for £200, but as its an auction who knows where it will end!
  5. Bump, i cant believe these haven't sold yet: http://www.ebay.co.uk/itm/4x-205-55-16-Avon-Winter-Tyres-Steel-Wheels-Toyota-Prius-Avensis-/191746238754?fits=Model%3AAvensis&hash=item2ca4f76922:g:VhkAAOSw14xWNhBT
  6. Hi All, The Prius has gone to be a Taxi and the buyer didn't want (at a fair price) an almost new set of wheels and tyres! so if anyone is after a set i have added an ad in the For Sale area and they are on Ebay at the moment. http://www.ebay.co.uk/itm/-/191728761360? http://www.toyotaownersclub.com/forums/topic/170367-4x-winter-wheels-tyres-5-stud-priusavensis/ Happy to answer any questions in this thread CC
  7. Hi, I have the following on Ebay at the moment http://www.ebay.co.uk/itm/-/191728761360? 4 x "Avon Ice Touring ST" Winter Tyres & Steel Wheels Tyres have between 7mm and 8mm of tread (measured from base of the tread) Prius has been sold and these wont fit on a Lexus RX :P ;) :D
  8. I will let the insurance company know, fingers crossed they don't charge us for it! The smooth power delivery of the auto will probably help the initial get away, the auto certainly wont stop the tyres working, Now back to my original question ;) , can i put 16" wheels on, as UK cars have 15" or 17"s
  9. Hi All, Is anyone on 16"s? I know the normal wheel size is 15" or 17" but can you fit 16"'s? I am intending to fit winter tyres to a set of 16" steel wheels. I know all about rolling radius's/ offsets/ stud patterns etc and i don't want to start a discussion about if winter tyres are required ;). So my question is can the Prius Gen 3 T-Spirit take 195/55 R16 87H's without invalidating the insurance or any other law! Thanks in advance CC
  10. They were talking rubbish, but as i've bought and sold 100's of cars i can see that. Not everyone has the knowledge though, when you pay premium prices for approved cars they should be high quality. All the previous Mr T cars i have bought have been fine. I'm not taring all dealers with the same brush :) I would imagine the F cars are registered in Derby and used by factory staff.
  11. I'm glad all the Prius's are like this, i thought ours was being odd! The range displayed 0 miles and it only took 32 litres!
  12. Save up and buy a SR180, chasing power on the old 2.0 litre will probably result in wrecking it.
  13. This has started to happen A LOT particularly at used car supermarkets. They Know 9/10 car searches start on the net and are priced to draw you in. The "web" price is honoured, usually by downloading a web voucher. Ive not seen it at any Toyota dealers around this way Kingo The problem is John you can't trust southerner's ;) When i sold cars we just wound the clock back and dropped a bit of saw dust in the gearbox, we never messed with the price :P
  14. Hi All, Having just picked up Mrs CC's new car i thought i would share my experience of buying it. Due to a positive change of circumstance we decided to get a bigger and cheaper to run car, this car has to be petrol and a Toyota so it left us at a Prius or a Auris. But as the Mrs doesn't like the Auris, it will be a Prius then. The car also cant be black or white. So off i go looking at post June 2010 Prius's, the best of which appear to be at Mr T. After a few phone calls i'm having sensible conversations with salesman who offer cap clean and a bit more for the old Yaris. This is a good start, although there isn't any extra discount available over the phone. We agree to disagree and the conversation ends. The next day we get in the car early and head to see car No 1 100 miles from home at Mr T. We find the car a Vermilion example and start poking around it. This car is a 2011 11' T-Spirit with 43k recorded, its a total shed. Scratched on each panel and the inside is even worse, yes Toyota plastics scratch easily but this is a joke. I request the service book which isn't in the car, the salesman advises it has full Toyota service history and was a management car. When i asked why it wasn't registered in Guildford (Reg not starting with a G) the chap has no idea what i'm talking about! The full history is a piece of paper, this shows 2 services instead of 4.... what a joke. Now this car is £13,995, not the £12,995 as advertised online, the explanation being web prices are lower. So if i walk in you will let me pay £13,995, yes is the answer. Nice! We walk away, Onto car 2 another 30 miles south at Mr T, this is another 2011 11' but with 24k and T4 spec, silver this time. Exterior is better but still covered in scratches, interior is a lot better. Now for the service book, again not present, salesman tells me its OK, its an ex enterprise hire car so they will have looked after it really? Where is the service book? Lost, but i will get you a piece of paper from them saying its been serviced. I ask what will Mr T say in 2 yrs when it needs a warranty repair, salesman says it should be fine....Now this car is £13,995, not the £12,995 as advertised online, the explanation being web prices are lower. So if i walk in you will let me pay £13,995, yes is the answer. Nice! We walk away, AGAIN. This is a joke, whats happened to the world? I'm not happy! Right car 3, not at Mr T, my last option that i don't really like as its at a car supermarket, i must be bias with Mr T dealers. So this is a 2011 11' T-Spirit with 65k, but it has a genuine Full Toyota History and registered in June 11 so 33mths of warranty to go (Mrs CC 7k per annum now). Ex Lease car. Its in great condition and the interior is good as well, it smells of smoke, dam it. But i can fix this, as i have done before . This car is £11,200, px price is good, deal done, car home 58.6MPG on the way back, well pleased, Boot liner and mudflaps on order. Very disappointed in the rubbish for sale at these 2 Mr T franchised dealers and the total lack of knowledge the staff have on service histories and warranty. So here she is
  15. Our old Verso produced this no power issue and shaking back in Mar 12 so i thought it a good time to swap her. It was due for a 80k service at the time, i wonder if it was the fuel filter that was full of water or clogged, i will never know. Has your's had a fuel filter out of curiosity?
  16. She looks a lovely motor Don, especially in Summer spec
  17. This good old thread should assist - http://www.toyotaown...howtopic=106241
  18. On Ebay - http://www.ebay.co.uk/itm/190753331743?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
  19. Hi All, I have this for sale on Ebay at the mo, the only reason its coming of is our Works insurer wont allow any mods at all going forward! So thats us back to the standard airbox - Yes it was only about 6mths ago i spent over £200 on this, dam it http://www.ebay.co.u...984.m1555.l2649
  20. I've just done 3,300 miles in Europe on hols and my Enterprise hire car (which has gone back now, more on that later) averaged 39MPG. Now some of that was 120MPH on the Autobahn but most in the 75-80 MPH area in the various countries with some slowing down in the rain (If you drive abroad you will know what i mean) and Urban/Dual Carriageway work. All in all really poor i'm afraid. This is the 2011 i have or had...
  21. This will help with the fault code http://www.toyotaownersclub.com/forums/index.php?showtopic=76527
  22. How come the graph doesnt have Reg No or Model, Data or Time etc etc? Its amazing how the solid lines look exactly like Mr T's claims and the other lines show what the box maker claims it could do...... Is that recorded off your car Pikey or just a sample image?
  23. If you hyper mile yourself and the car to death you probably could get those figures, but in reality who lives like that? Did they drive in the middle of the night and sleep in the day?! Air Con off, Tyres at 60 PSI etc etc Simple answer to this is go on a test drive at 70MPH between the same motorway junctions reset the MPG on the computer and see what it displays. You never know it might just do 55-60...
