Did the lights come with the handles? Did you buy all from Audi?
Also what's the on off and 1 2 3 set buttons all about?
Yeah the lights come with them, not sure if they're standard in all cars but the stock ones are really dim - you might have them and just not have noticed. Very subtle red colour around the inside of the handle.

The buttons and numbers are for the power seats, it's the memory positions

I was gonna say I've not noticed that I've even had any so they must be very dim! I don't have the power seats on my black edition ?

Got Android Auto installed after about three weeks of pain. Installer said it was up there with the worst jobs he's ever done. Still got a couple of snagging issues but it's pretty much what I hoped.

Had a couple of issues come up over Christmas/new year - was driving along and got an ESP fault - loads of codes like ABS modules, suspension sensors, and no signal/communication with the ESP module. Took it to a local VAG specialist who diagnosed an electrical fault with the ESP sensor which would be £950 to replace :oops:

Got a reconditioned sensor off eBay for £65 and fitted it myself - it lives under the passenger seat so was seat out, cut the carpet to remove the vent on the chair and then the sensor is under that. Hardest bit was getting the vent back in properly:


Still need to take it back to get coded in later this week but fingers crossed that sorts it. Put LED interior lighting in over Christmas so hopefully it's just a coincidence and I haven't done something that's causing electrical gremlins.

While the car was in the garage, they noticed my passenger window regulator had gone too :( £450 for them to replace so got an OEM regulator and did it DIY. Managed to get the adjustment spot on which made me realise my driver's window was way off. The adjuster on that had seized and when I tried to turn it it made it worse, so need a bit of time fannying about with it but got it sorted eventually.

2.5 hours on ODIS today running test plans for the ESP issue - looking like electrical fault and is suggesting wire continuity testing :confused:

Got the car back today - faulty abs module. Probably going to send it to ECU Tuning to get it reconditioned as new ones are about £1300 and used ones on eBay look rough. Glad I didn't pay the first garage £950 for a new ESP sensor now!

Where did you get your boot lip spoiler from and how much did that set you back? I have been trying to find one of these for ages and can not get hold of one

Car is going back into DH Automotive on Tuesday to get the ABS pump removed and sent off for a rebuild.

Was driving home there and got the full complement of lights, ABS, ESP, parking brake malfunction and range control defective. Starting to lose faith in the car a bit, hopefully it's the dodgy signal from the ABS pump causing the gremlins and that sorts it.

Saw a really nice TTS for sale the other day at a really fair price - might be tempted if this issue keeps dragging on.

We had the ABS pump out and sent it off to ECU Testing who checked it out and said the unit was operating as expected :( so ended up back to square one. Dave tested all the wiring and did more fault finding but said everything was pointing to the ABS pump being faulty.

Ordered a second hand unit off eBay so we can use it as a sense check but need to wait for lockdown to finish so we get it coded in and fitted. By the time we take the pump out again and remove component protection this is going to sting a bit.

Didn't have my car for a few weeks while it was in for testing so took a mk2 TTS for a test drive - quite liked it but the cabin is super dated and the spec on some of them is terrible! Think I'm going to keep my A5 for a bit and then maybe look at a mk3 TTS once they depreciate a bit more.

Finally - after about five months with a symphony of warning beeps when starting the engine - the car is fixed.

Back in January my ESP light came on randomly while driving, took it to a local place who said it was a faulty ESP sensor which would be £950 to replace.

Got one off eBay and fitted it myself but that didn't fix it so took it up to MRC - they did some further tests and updated the software on the ABS module which helped narrow the issue down and it looked like a fault with the ABS module, so that came out and went off to ECU Testing. They bench tested it and said it checked out so back to MRC for more investigation.

Had to take the car back due to lockdown and during that time I was getting 40+ faults on a scan, stuff like component protection active on seats, communication with other modules dropping off and other weird stuff, which maybe pointed to a battery/voltage fault. Got the car back up to MRC last week and the battery was fine but alternator wasn't charging high enough. Replaced the alternator, most of the faults cleared, but the ESP sensor flagged again so seat out, no issues with the sensors, but they found some corrosion in the plug itself so that had to be cut and repinned.

After that there was still a residual issue with the ABS - bad signal to the module and also not communicating properly with the rear left sensor. Wiring testing found a poor connection to the module for the rear left sensor, and then finally, in the loom that runs behind the wheel arch:




That was fixed, road tested, and finally it was done.

Got a couple of service things done too while it was in - rear pads and discs changed, and the thermostat was knackered so that got replaced too.

They think the ESP sensor under the seat must have got wet at some point, e.g. if something was spilled down there. The broken wire in the door is a bit more of a mystery, I had a repair done in there back in October so whether it got pinched when they were doing the repair and that allowed it to corrode, or it just something random, who knows.

Collection day:



As expensive as that was, I'm still delighted to have the car back and working. Had been thinking about selling it and getting a TTS but not sure this is really the best time to be buying a car, and I'd have taken a bit hit trying to sell it with those faults anyway.

Jobs for this weekend - give the glass a machine polish. The side windows are marked from going up and down, and the windscreen is a nightmare to see out of at night - wondered why this was the case but apparently years of scratches and swirls make the light refract differently so going to tackle that.

The car wasn't getting up to 90 even after the EGR thermostat was changed, although it was rising quicker and was steadier - had a quick chat with Dave at MRC and he said to swap the coolant temperate sensor.

Really quick job - literally two minutes - although took a bit of looking about to find the stat. There it is:



And now:



Weirdly my coolant level seems to have risen:



Lost a tiny bit of coolant when changing it over but it's at the top of the system so we're talking drops. Was concerned about air getting in potentially but read a couple of guides on doing the coolant stat and they didn't mention any issues with this.

Was out yesterday but only for about 15 miles over three trips so didn't really give it a good chance to heat up, but it got up to 70 quickly enough then hesitated went back down slightly. Was going to go a longer run but got a parking space right outside my flat and the weather was too nice so took the dog a walk instead.

Few weekend jobs:
I'd wrapped all my silver trims in stain black apart from the centre console surround - I thought the silver was a nice contrast but got some decent carbon fibre stuff to see if it would look better wrapped, and it does.

Also installed the newer start stop button:





Now my OCD is twitching and wondering if all the trims should be wrapped in the carbon - did a door trim to see and not sure:



Think I prefer the satin actually:



But gonna it a few days and see how it goes.

Was out for a good 30-40 mins tonight, did 25 odd miles of mixed driving and it didn't go above 70 really :-(

Guess the main thermostat appears to be the likely culprit now. Seen a few people saying you can do it by removing the airbox and push the aux belt out the way, but i wouldn't be comfortable doing that myself, and i think the textbook method is front end off. Another trip to the garage...
