Dear All,

Re 2006 Aurion Presara

It has been a while since my last post, basically because I have had very few significant issues! The car has been awesome!

I currently have a very strange issue with the settings on the AC Controller being lost. It happens after the car has been sitting unused for a while (usually overnight). When I start the car all of the AC control screens are blank (the front screen demister light is flashing) and after one or two minutes the unit starts up. I then have to push Auto and the unit gets going with 25 degrees C on both sides (presumably this is a default setting?). Otherwise the air con works great. Short periods between drives the car is fine. Long periods is when I have the issue.

So far I have checked the ECU-B No 1 fuse (no fault found). I have even actually replaced the control unit itself (as I had a spare when I replaced the sat nav assembly. Still no change.

Any ideas what it could be please? Many thanks in advance, Rob

I have exactly the same problem with a 2015 RAV4. The car has travelled very low kms and has just had the original factory battery replaced as RACV tested and advised that the battery was nearing end of life and that the low voltage may have caused this problem. 

However after change to a brand new battery, the same problem still exists as the post from Erebus.

Does anyone know of a solution please?

Kevin

      Aurion tyres

      I recently fitted Nexen Nfera Su1's and am very happy with ride & grip quality. These are supposed to be a mid range tyre. I couldn't find any in your size on tyroola, but they did have a set of 225/50/17 for $600 fitted (if your living in Melbourne) https://www.tyroola.com.au/nexen-n-fera-su1-xl-22550zr17-98w-ty66a1e88c5a.html Cant go wrong with the extra width 👍

      Aurion tyres

      I've used Kuhmo on my MGB for years and find them a good reliable, mid priced street tyre. Probably any tyre on your list will do, also Bridgestone. What tyres are on there now? Hherb

      Corolla Ascent Sport.: Model ZRE182R.C

      Hi Alan, My first reply, as I just joined up 🙂 I have a 2016 Corolla Ascent Sport Hatch with alloy wheels so I'm guessing yours would be the same. AFAIK don't think Toyota has the colour code for the alloys, think they're just a generic silver. Before my son got his licence a few months ago, he had scuffed the front and rear left alloys of my Corolla a bit while I was teaching him to drive. I found a silver touchup pen on Amazon for Alloy wheels, was pretty cheap for just under $10 and the colour is pretty much the same silver. Worked a treat. Maybe buy one and see if it matches the colour of your alloys. If it does you could get an auto paint store to match that colour. Just do a search for "alloy wheel touchup paint" on Amazon. See the screenshot I've provided. All the best mate.

      Thanks Robert! Too true, dad was devastated when the Aussie car manufacturing industry shut down. Sad as it is, I've been very happy with my Toyotas like yourself, they are just awesome work horses. Cheers mate, see you around 😀

      2016 Hilux SR5 Coolant Issues

      The first picture is what the initial mechanic in Port Augusta analyzed what was wrong with it. The next 3 photos shows what it did look like. The last photo is how it looks now repaired. I hope that helps you understand what has happened. From what I can tell from other forums is that there used to be an issue with the coolant leaking which probably led to this one being bypassed. Hence the issue as outlined in the first image. I was told by my mechanic yesterday that bypassing the coolant through the engine is illegal and should never have been passed for a roadworthy when I bought it back in April. It is an emissions issue and you don't touch that area. He said that if was presented with this ute in that condition, he would not have passed it for roadworthy. I have been in contact with the dealership that I bought it from and he is going to look into the mechanic who did the roadworthy and find out what is going on. I have said that I want to be re-imbursed for the repairs and being sold a faulty car, as well as that I nor he would want me to go to VCAT or Consumer Affairs about it. Are you aware of this issue?

      Son's First Car--98 Corolla Seca--Overfilled Oil--Cactus??

      Thanks so much for your advice. We checked the transmission dipstick (finally!) and it was empty! Yes old dad did a boneheaded move. My son then changed the oil and filled the transmission fluid on his cherry 98 Toyota Seca and the car sings! Thankfully our 100m test drive on no transmission fluid does not seem to have done any major harm. Cheers

      Son's First Car--98 Corolla Seca--Overfilled Oil--Cactus??

      Just to confirm, are we talking about engine oil or gearbox/transmission oil? The auto in these also has a dipstick in the engine bay, just want to make sure you're checking the right thing (especially since you're talking about it not shifting properly, which shouldn't be an issue with engine oil level if the car runs fine otherwise)
