  1. No, leave well alone and stop worrying about the DPF! We've owned our 2012 Avensis d4d since late 2015 and have never noticed it do any obvious regen in all of those years and 95000 miles. The DPF is still fine though. You'll do far more harm to the DPF in carrying out unnecessary forced regens than just leaving it to do its thing.
  2. The purpose of a brake booster is really to make the brake pedal easier to press for the driver, it will not make the brakes themselves more powerful as such. It sounds like perhaps your brakes need a full strip down and checking, if that has not been done recently. Also worn tyres can have a significant effect on braking distances but you won't necessarily be aware of it as, instead of the wheels locking up and tyres squealing under emergency braking, the ABS will just cut in much sooner and increase the braking distance.
  3. So does ours, but unfortunately they seem to use rubbish quality batteries! On a couple of occasions we've had a low keyfob battery warning relatively soon after the car has been serviced. Upon opening up the keyfob I've found an obscure make of battery when I know I've previously fitted Panasonic. The Panasonic batteries generally seem to last two years or so with regular use.
  4. That's on a par with me discovering that my (at the time) newly purchased property had rotten floorboards, and in my annoyance bringing in the 'For Sale' sign and sawing it up to repair them. The current homeowner won't know exactly who did it, but they will have a fair idea which estate agent the person who did it bought the house from..
  5. Engine covers may serve a purpose when a car is relatively new, but on older cars they can become a pain. On my 2009 Auris some ham-fisted mechanic had broken one of the fastenings off, resulting in the cover never fitting properly again, and it resting on the ignition coil wiring. I tried to glue the broken part back on but could never find an adhesive that was strong enough to hold that type of plastic in the heat and vibration of the engine bay. On a Peugeot HDi I owned years ago the engine cover had, despite being intact and apparently fitted correctly, somehow rubbed and chafed the insulation off parts of the injector wiring loom hidden beneath it. On our current Avensis one of the breather hoses had popped off and, unseen under the the engine cover, sprayed everything in the vicinity with oil mist residue. Had there been no cover in the way I would have spotted this within days of it happening and re-attached the hose, rather than weeks/months later when I happened to take the cover off for another reason and saw the problem.
  6. That's interesting, I'm English and an accountant and I hate engine covers. Perhaps dislike of engine covers is an English accountant thing? 😉 To me they're just a piece of unnecessary plastic, I'd rather see the engine when I open the bonnet.
  7. You'd think so, but whatever software turns the fuel metering data into a dash MPG readout is far from exact in many cars. I've compared long term actual fuel consumption versus fuel computer display consumption in a variety of cars over the past 15 or so years and the dash MPG readouts are frequently +/- 5-10% out. The MPG display in our Avensis for example has always been around 8% pessimistic for all of the years we've owned it. Conversely the MPG display in a Skoda Octavia TDi I used to own was consistently 7% optimistic, that is until I tweaked it with VCDS to make it accurate. VW Group even acknowledge the inaccuracy of their own fuel consumption displays from the factory and allow dealers (or anyone with a VCDS cable) a means of adjusting the readout by a specific percentage to make it correct.
  8. I'm not really familiar with the 2.2 engine but that looks like the fuel fuel pipe leading to the injector. It appears to be compression from the cylinder blowing past the injector seal. As far as I know its a rare problem on Toyota diesels, but can be quite common on certain Merc and PSA/Ford engines. With the engine running can you see or hear exhaust gasses leaking out past the injector? If so I think the injector will need to be removed, new seal/s used and possibly the injector seat recutting.
  9. I think motoring journalists often just regurgitate the brochures and press releases handed to them by manufacturers, and don't really understand the technical issues very well. They resort to mentioning nonsense like dash plastics because they don't know what else to talk about. I recently saw a review of a Hyundai hybrid where the journalist was waffling about the gearbox being different to 'the clunky belt-driven transmissions in Toyota hybrids'. What?! The only belts in a Toyota hybrid are those on the seats, or perhaps holding the driver's trousers up.
  10. That was certainly true on Volkswagen PD diesels, and VW did refer to it as an 'anti-shudder valve' on those. I'm not sure though on common rail diesels whether it still performs that function. I previously ran a Peugeot 2.0 HDi with this flap disconnected for a while and it made no obvious difference to the running or engine shut-off as far as I could tell.
  11. They mentioned the scratchiness of the interior plastics though, that's the one thing that motoring journalists really care about. You could give them a milk float to test drive and as long as it had a German badge and a really soft facia they'd be happy 🙂
  12. Yes its not really a throttle in the way a petrol engine would have, I gather that its purpose is to close partially when the EGR valve opens to force the engine to suck in more EGR gas and less fresh air than it would otherwise.
  13. I've been taking various diesels for MOT tests fairly regularly since the mid-1990s and I've honestly never seen anything measured other than smoke!
  14. I think you're thinking of the petrol emissions test results? All the diesel MOT test printouts show is the smoke reading (or readings if they had to do more than one to get a pass) and sometimes the engine oil temperature. It is very much a 'lowest common denominator' test, dating back to the days when the only issue with diesel emissions was considered to be black smoke. You could indeed remove the cat and it would still pass. I once did exactly that with a Citroen Xantia turbo diesel. The MOT smoke emissions results were slightly lower with the cat removed, and it gained about 2 MPG! Hence why a visual inspection for the presence of a cat was included in the MOT test a few years ago.
  15. Diesels still only have to pass a 'smoke test' for the UK MOT not a full emissions test, so increased NOx shouldn't be a problem as far as the MOT goes.
  16. The only recent-ish car I've had with a low washer fluid level warning was a Skoda Octavia, and that particular spec only had it because it was also fitted with headlamp washers. The headlamp washers were great in winter but they used up washer fluid like it was going out of fashion.
  17. How do you know it's low boost? On your other thread you started off suspecting the 5th injector?
  18. Its unlikely to be the turbo if its white/grey smoke. Turbo failure seems very rare on this engine in any case. I'd guess (but its only a guess..) at the injectors, either the 5th injector or one or more of the 4 main engine injectors but really you need more diagnostic work to pin it down.
  19. Sorry to hear that. Injector cleaner is worth a try certainly. What can sometimes happen is that the oxygen sensor, or the cat itself, can be slightly borderline and just trigger a fault code occasionally. My son in law's Aygo used to do it about every 6 months or so but run completely normally the rest of the time.
  20. I wouldn't count your chickens just yet, it may be an intermittent fault which will come back. Although some do recommend using 'branded' fuel over supermarket sourced fuel, if it makes any difference at all (which is debatable) it will be over many thousands of miles, not a couple of days. I fear the mechanic may have fobbed you off.
  21. Generally speaking its only the hybrids which thieves target because the cats on those are worth more.
  22. That does seem to be a peculiarity of German cars (and Vauxhalls due to their Opel origins, plus Skoda and Seat as they are part of VW). I've not known this feature to be fitted on cars from any other part of the world. It is usual for the instrument panel lights to be on with the parking/postion lights on most cars.
  23. That is true if the primary tyres are not directional. I tend to fit all season tyres though which are often directional, so it's not really practical to rotate the spare in with them. Obviously you don't want to end up with a directional tyre as the spare as it would only work properly on one side of the car.
  24. I would always choose a spacesaver over a tyre repair kit. I've had a few bad punctures over the years which no amount of the silly gunk in a tyre repair kit would have fixed!
  25. Both batteries had been charged up to capacity with a CTEK charger a day or so beforehand, so both should have been in a very good state of charge before the test. I appreciate that voltage when charging isn't the same as charging current. However the way I'm looking at it as a very rough and ready method of say, switching the headlights and heated rear window on in the hybrid makes the voltage drop from 14.1V to 14.0V, whereas doing the same on the diesel makes the voltage drop from 13.9V to 13.4V, both with fully charged batteries, then that is a reasonable indication that the hybrid has more spare charging capacity than the diesel?
