Hi, On my 2008 B7 A4 Cabriolet, one of the electric wing mirrors has stopped moving when I try to adjust it via the internal adjustment knob. It's been like this for about 6 months. The strange thing is, over the past six months, I've tried it every week, hoping it would fix itself. On two occasions, it moved a tiny amount before stopping again. There are no fault codes showing up. The other wing mirror works fine, via the same adjustment knob. Can someone please guide me on how to diagnose what might be the problem? I don't know if it is wiring, the motor in the wing mirror itself, or something else completely. I'm good at most things car wise, except electrics! All other electrics work fine. Thanks! Sammy

Thanks Steve

Hi, I have a couple of strange issues: The driver's side window on my B7 convertible sits about 1cm high when lowered, instead of disappearing fully in the door, like the passenger side. I think the driver side window should go fully down, can anyone confirm? Also, I have convenience windows, but the remote does not lower or raise the windows. BUT, using the key in the door does. Can anyone advise? I have read a LOT of threads about windows and have tried all the reset methods etc, but can't find a solution to this The car also shows no fault codes. Thanks!!

Hi, I have same car and engine and almost same age. To diagnose the thromostat, if you are stuck in traffic, does it stay at 12 o'clock, and if you start driving say, above 50mph for 10 mins, does it go down to 10 o'clock? If so, the thromostat needs replacing. I did mine two weeks ago and now it stays on 12 o'clock all the time Also, check your oil level on these engines, they can burn 1 litre of oil for every ~600 miles (as stated in the manual). I do not have a high pitched noise in 2nd gear btw.

I use autoglym stuff, and Simonez wheel cleaner and shampoo. I have read that Collinite 476 wax goes well on top of Autoglym super resin polish, so I will try that soon

Hi Ian, I really don't know. I'm doing the long runs as well as the Redex (I bought a 4 pack from Costco, so I'm set for at least 6 months). But I really don't know if Redex helps. From what I've read, it doesn't do any harm... unless someone on here has better/more proven experience with Redex?

Thanks all. I bought the original part today. Although, I did find a Hella branded one on Amazon for £43, but I had already purchased the original part by then. I'll let you know if I manage to fit it successfully - I need to take the front bumper off - Yikes!!!

Hi, I need to replace the A/C pressure switch on my Audi A4 (B7) cabriolet. The local Audi dealer is quoting £79.60 for an original part. My question is, is it worth paying the extra for this original part, versus £33.88 from GSF (no brand mentioned)? I don't mind paying the extra if it's worth it... Thanks! Sammy

Mine has the same, it looks normal to me

I have used the heated washer jets fuse successfully on my 2008 A4.

Glad I could help!!

Quote I got a month ago from my audi dealer was £170 for the key, and then roughly the same again for the labour. I recently got a spare key from an independent key specialist - Car Key Solutions in London. It's not an official Audi key I think, but looks and feels identical - that was £165 all in, including coming out to you to do the work. I had a couple of issues with that, the remote buttons stopped working, but the Car Key Solutions customer service was top notch and they sorted it for me.

Just an update to say I had a service (all filters and oil and plugs) and the stat was replaced. Running really nice now. I will use RedEx for the next few months, can't hurt...

Thank you 🙂 Looks like I need to to a clean and protect routine a couple times per year. I'll give these products a go. I know you must be thinking "why doesn't this guy just Google it?!" But I had already done that, I was wondering if there was some sort of professional protecting option people has used, that they could recommend. 'I'm not a lazy forum user, honestly gov' 😀

I just received my car yesterday having changed a stick thermostat (same symptoms as you). It's running perfectly now. My car is only a humble 2.0TFSI, the genuine VAG stat cost £48, plus 1 hour labour. I had the car serviced at the same time, and just need to take it out for a good long fun run!

Hi, I recently bought a 2008 A4 Cabriolet, which had previously been stored in a garage. As such, the roof is pristine. I don't have a garage so I would like to protect the soft top roof as much as possible. Can anyone recommend a treatment, to prevent algae, and for general protection in wetter seasons? I don't mind paying for a professional job if such a thing exists, or doing it DIY. Thanks! Sammy

Hi, I found this tag attached to the lower dash where the manual lives. Can anyone tell me what these codes mean? Thanks! Sammy

Thanks, Gareth. FedEx/ RedEx - Ha! Sammy

Hi, My petrol 2008 A4 2.0 TFSI has a thermostat stuck open, and doesn't get up to temp (90 degrees) unless I'm stuck in traffic or going slow. It's booked in for a repair on Monday, so hopefully that will fix things. I will also ask for spark plugs to be replaced on the basis of the rich mixture affecting them. My question is, since it's been running rich, should I clean the engine somehow? What do people think about those additives like redex? Or, should I just forget about it and not doing anything after the repair? No fault codes are coming up, so everything is fine apart from the engine running cool. I am *assuming* that the engine is running rich, because it's cool - rather than a fault code telling me it's running rich. I still want to get the thermostat fixed either way. Thanks!! S

Maybe the OP has already solved this, but I also give a +1 to OBDeleven.

Hello and welcome

Thanks Steve, it's definitely a great way for a beginner like me to get into the diagnostics and coding arena.

Update: I bought obdeleven basic from Amazon, and then bought the pro licence from within the app. I successfully used it to read fault codes, but also to code a retrofit RNS315 in my VW Touran. Using VCDS 'how to' videos, I can find the corresponding values/bytes/bits in OBDeleven. Good kit! All in, cost me under £100 for the pro package.

Just want to add for any future readers, that on my 2008 A4 B7, I used the heated washer jet fuse, which is also on with the ignition.
