Is there a method to get power from the mirror using an adaptor, I have seen several clips on YouTube but didn't know if anyone had tried on a Audi?

The car is now sold

Gonna get it checked by a VW specialist first, the dealer will likely try to bodge/cover it up etc. I'm sure a pro will just drive it for 5 mins to see the issues. I'm kicking myself, British roads so bumpy I couldn't tell in the test drive so many potholes I want to be armed when I go back, main dealer I got it from,17k with warranty.

Nevertheless if it is the original battery it is long overdue to be changed irrespective of any sensor fault.

I have to agree with Cliff I suspect it's the amplifier. I'd recommend a diagnostic check to see if any fault codes flag up

Yep a c8.

Please keep us updated on how you get on

I'm near Leicester. I used AC motors on wanlip road in Syston. They're very good. You also have vee dub in Queniborough but I've never used them. Chapmans independent audi specialist in Wigston but again not used them.

I have the same on a Q3 sportback 2024. Audi have had it 3 times and have now told me that’s what it’s supposed to sound like. I said what Audi have purposely added a really annoying noise on an expensive car as standard. They did change the activated charcoal line in mine as that is a common issue as they split but it has made no difference. I have had other mechanics say it could be transmission, turbo, air intake timing belt/chain or electrical. I said to Audi what I don’t want is to come back when it’s out of warranty and then be told I have a big problem and it’s going to cost me a fortune. The thing is quite a few people have the same issue so there has to be a problem.

Hi Gareth, sorry missed this earlier 🥱 I’ve had a couple of quotes and it’s only a little bit dearer than the citron C3 we have now, and I have told them that it’s a jap import. I’ll have a search and see if I can find out anything about oil issues. thanks

Thank you for answering, I think it might be easier so if I just get the bluetooth adapter for the back of the original Concert unit instead as I am looking for minimal hassle.

Hi - had the same problem and my local garages did not the soft ware to unlock the unit. However I found a local auto electrian who had the software and he successfully unlocked it.

Many thanks Richard for your help. I have dismantled both front brake calipers and though the pads and discs are as new, all was really dry of grease. Using the ceramic I greased all as appropriate. Just done a road test the rattle has basically gone. Only a little rattle over pot holes which should avoided anywhere. New caliper springs and gease up -job done. Thanks again.

Thanks Tavi - this worked for me.

Keep us updated Gustaf. Does anyone know if the brake calipers are the same on all models? I've got a 2015 BiTdi Allroad so trying to identify the correct parts for it. Thanks

So as I thought no screws in the slide out panels or under the triangle, just a load of push in clips that need a bit of gentle persuasion. I used a trim tool bought in readiness, Wetado 8 piece £9 on Amazon, to get the right hand side off first then just gently work all the clips out. The light and boot switch have a small push down clip to disconnect the wiring plug. The adapter for the wiper washer, picture attached is blocked

This thread will now be deleted.

Hi, do you have any parts left?

Hi, It's almost impossible to hear it when driving, I only really hear it when the car is ticking over, so I'm not sure. It only seems to start about 20 or 30 seconds after I start the car as well, not as soon as the engine starts.

Ideally scan the car with VCDS to see if it identifies the module that’s not communicating. There’s a Bluetooth module, but I’m guessing. An auto electrician is probable a safe bet with access to diagnostics. https://www.lllparts.co.uk/catalogs/audi/RDW/RS4C/605/0/035/35010 Not sure if this unit is under passenger side seat or in boot given cabriolet could be a different set up given potential for the interior to get a soaking.

Ethan. Your frequent refilling and short journey make me confidant there has been no damage. No guarantees of course, but I would not be concerned if it was my car.

Thanks Ian, You now need to start testing for voltages and good earths using your multimeter. Regards, Gareth.

Cliff Many thanks for the information, I will have a look to see if this can be disabled. It does not really cause any trouble; I was a bit worried when I first saw the error but I now know that the car will charge with no issue. The MyAudi app for the Q4 is not as good as the app for my previous car A3 8Y, at least I could lock the car if I was away from the vehicle not available in the Q4 version.

Thanks for the update Tony. Note that the job is not trivial so it would be worth renewing the water pump at the same time while the engine is apart. The pump life is similar to the belt and requires the same effort for access, hence the recommendation to do both at once. We have noted before problems with forum access when done through Google. I don't know the details or whether a solution was found.
