  1. You can get a lot of part numbers by browsing this website: https://www.amayama.co.nz/en/catalogs/toyota/avensis
  2. That's interesting to hear because my Bosch A539S blades fit perfectly to the wiper arms with no free play and the locking button is in the correct location.. I wonder if there was a bad batch, with the wrong connector installed on the assembly line, because I noticed a couple of reviews on Amazon.co.uk said the Bosch A539S didn't fit their Avensis and other reviewers had no problem?
  3. My repair only cost what I paid for a small can of electrical contact cleaner and now it works as good as new.
  4. I'm with you. The low-speed ride on anything but perfectly smooth roads is far too jiggly and unpleasant.
  5. Only the driver's side rear fog light contains a bulb and wiring. I replaced mine a couple of months ago after the lens was cracked. I did it myself and it was surprisingly simple. Bumper cover removal: It wasn't easy finding a replacement light assembly, as the genuine part is no longer in production. I purchased the genuine part off eBay. It's actually produced by an OEM parts supplier called Valeo. Here's a link to what's currently available on eBay: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw=Valeo+44916+rear+fog+light&_sacat=0&LH_TitleDesc=0&_odkw=Valeo+44916&_osacat=0
  6. I'm sure this topic has been discussed before on this forum, but I just performed this fix on my T27 Avensis and the following video made the process so much simpler than it otherwise might have been. The most difficult part was trying to remove the piece of dashboard trim that contains the centre air vents. In the end I gave up and only prised out the bottom clips on the head unit surround far enough to remove the climate control unit.

  9. Well, I'm pleased to say the Bosch blades did the trick. No smearing and they're extremely quiet. It seems that with these super-long blades (longer than 24"), even pressure along the length of the blade is critical. I noticed the Bosch blade has a much tighter curve on it when lifted off the windscreen than the other blades I tried. I think the after market blades were applying too much pressure at the centre of the blade.
  10. I don't believe this. 11 days after installing the new throttle body, the original problem has returned! The Toyota dealer suspected an issue with the Valvematic controller, but I don't believe this is the case. A fault with the Valvematic controller should result in a fault code and check engine light, which I don't have. In addition, you'd expect drivability issues, e.g. a lack of power. My engine performs perfectly at all engine speeds. What I do know is if you unplug the MAF sensor, the problem goes away. With the MAF sensor unplugged, the ECU will run in "open loop mode," meaning it ignores all sensor readings and uses fixed settings for things like ignition timing and air/fuel ratio. I've already replaced the MAF sensor, by the way. I had found this other thread discussing the same issue affecting other *brand new* Toyotas with a 1.8 litre petrol engine and manual gearbox, but apparently only in sub zero temperatures. I wonder if it isn't an ECU programming issue, where certain sensor inputs result in it having trouble setting the correct idle speed? https://www.toyotanation.com/threads/idle-hunting-when-cold.120207/ I'm loathe to spend any more money randomly swapping parts, but wonder if it might be the coolant temperature sensor?
  11. An update: I ordered a new driver's side wiper arm from Japan, but unfortunately it made no difference. So with a new wiper arm, new blades and a perfectly clean windscreen, I Googled the problem some more. That's when I found owners of other brands of cars reporting exactly the same issue with flat beam-style wiper blades in lengths longer than 24". It seems to be a common issue with a lot of beam-style blades 26" or longer, where there's insufficient tension (curvature) in the blade, resulting in too much pressure being applied to the centre section, relative to the ends of the blade. One possible fix is to grab both ends of the blade and bend them downwards until the two tips almost come together, forming a circle, and then let it return to its natural position. This effectively increases the curvature of the blade slightly. I tried this and it partly resolved the issue, but not entirely to my satisfaction. I've now ordered a pair of Bosch A539S blades. Apparently these blades are what Toyota originally fitted at the factory. Despite the blades I have now being a genuine Toyota part, they seem to be a different design, with a narrower profile than what I've seen on other Toyota Avensis cars the same age as mine. I was encouraged by two reviewers of the Bosch A539S blades on eBay making the following comments: "After unsatisfactory performance caused by slightly weak centre wiping on the down stroke - even after cleaning the blades and the screen itself - I ordered the Bosch Aero-Twin A539S. What a major difference! I these wipers clear the screen properly, with even pressure across the whole blade, clear in both directions." "Even when I got the dealership to replace the wipers on my car with manufacturer's OEM spec wipers, they kept smearing on the return stroke. Fitted these and - no more smearing."
  12. Hey guys, I've come back to report the "cold idle bounce" issue has been resolved! After reading about an Audi owner with exactly the same problem ( https://www.audiforums.com/forum/audi-a8-10/cold-start-idle-bounce-2-4-times-141756/ ) I took a punt and ordered a new throttle body assembly for my Avensis. Not a genuine Toyota part, mind you, as the price was ridiculous, but a new after market part from rockauto.com. Unlike the Audi throttle body shown in the link above, the plastic cover on the Toyota throttle body is secured by rivets, so I couldn't simply unclip the cover and clean the electrical contacts inside. Installation was super-easy, as per this video:
  13. When I purchased my T27 Avensis, the driver's side wiper blade was smearing a bit on the return stroke. I just assumed the blades were worn, so I replaced them, but that didn't solve the problem. I've now tried three different brands of wiper blade and they all exhibit the same issue: they clear the windscreen perfectly on the upwards stroke, but on the return stroke there's one spot that smears, right near the centre of the driver's side blade in about the bottom third of the wiper's path. It's almost like there's not quite enough pressure being applied at that point. Does anyone else have this issue (I'm wondering if it's a design flaw)? My windscreen is in good condition and perfectly clean (I even used special glass polish on it to see if that would help). The wiper arm is in good condition and seems to be perfectly aligned. The brands of wiper blade I've tried are: Tridon (an Australian OEM parts supplier) - these were on the car when I bought it Some Chinese blades from aliexpress.com Genuine Toyota blades (on the car now) One I haven't tried is Bosch Aerotwin, but I'm doubting another brand will make any difference.
  14. LED DRL bulbs don't work in the Avensis. Many people have tried, including myself.
