After years of avoiding automatics because I thought they were slow and sluggish I was forced by knee problems into buying one, and bought a cheap A4 Multi-tronic, expecting to hate it, but found it was really good, so I decided to upgrade. I've had an A6 C5 Allroad 3.0 Tdi manual on coils in the past, which I loved, so I thought I'd try another, but couldn't find one locally when I needed it, so bought a Volvo XC70 with the D5 & Geartronic as an alternative. Big mistake. Its a barge on wheels. Horrible to drive, slow and drinks fuel, so when I saw this 2.7 Tdi A6 C6 Allroad Avant with Tiptronic I jumped at it, and apart from minor teething problems with the electrics (see other posts) I absolutely love it. Not sure why you'd want quite so many ways to change gear, but hey: its smooth and quick. What's not to like? Anyone want an XC70?

No probs at all

When I bought the car the driver's door would unlock remotely, but not the passenger door. After a few days the driver's door packed up too. I changed the passenger door module for one from a breaker, which worked half-a-dozen times, then stopped. I exchanged it for another, which didn't work at all. I swapped the driver's door one, and this didn't work either, so I exchanged it, and again the replacement didn't work. Also the key operated window lift which has worked up to now stopped working! I'm wondering if I've been unlucky with 2nd hand units, whether I've been given the wrong parts, or whether there's something else going on. As far as I can tell the door control modules are all part number 4F095979 and then 2 for NSF, 3 for OSF, and 4/5 for the rear doors, but people list them differently. Also there's a range of suffix letters, I've come across P, E, T & C so far. Can anyone tell me what part numbers I should be looking for, and suggest any explanation for my lack of success? On the +ve side, I'm getting pretty slick at taking the door cards off! Thanks

If anyone does have difficulty with there ABS module with this fault reflashing it using Odis usualy solves the problem

atleast you can rule out the battery.

Hi unsure if people still reply on this but I have the same issue and it's come up with 3 fault codes , I've read the throttle sensor can make the car go in limp mode .

That must be about the only electrical problem I haven't had on mine yet Steve!

Ah, an R8, I can only dream! Lovely car mate, and welcome to the group. And I'd love to see some pictures of your car if you get chance to post some.

You'll need a diagnostic check to see if any fault codes flag up. It's probably the roof clamps that has failed. Problem if you can't get into the boot as you could manually control the boot from there.

I know how this feels. Still need an engine for my A6. All the second hand ones don't come with service history or unconfirmed mileage etc.

Get the part number and buy a second hand headlight to see if that cures the problem.

Try this mate, I don't know if it's applicable to your model and year but it worked perfectly for me so it might be worth a try. 2003 A6 C5 key reprogramming (two key method) - Audi A6 (C5) Forum - Audi Owners Club (UK)

Hi Val, I have the exact same issues, TPMS light on dash is on with messages on Auto Stop/Start failure, Stabilisation control ECS/ABS fault and Tyre pressure system fault. Was it the TPMS bulb on the dashboard that had fallen out or was it a sensor elsewhere? Appreciate the help, thanks

Unless the service plan is through VWFS (Volkswagen financial Services) I wouldn’t bother. the T&Cs through this service plan scheme ensure any dealer network franchise coverage as well as additional leverage to resolving complaints or defects thereafter a service. having worked in the motortrade I have sold used car service plans; you often read genuine parts and this is not always the case and I have often seen inspections and oil changes being done in 20 minutes or less. The oil gets changed but the inspection in my opinion is not the same. Main dealer networks rely on high turn over of customers in and out the doors. They pay their workshop staff bonuses based on speed not quality. echoing what others have said id personally put money away and chose an independent specialist where your get main dealer experience and better value for money, in most cases.

The visual level on the dipstick is the one to rely on. The electronic level sensor sometimes goes awry and should be renewed.

Hi, can anyone help me with a problem I have with my air conditioning, when I start a journey my air conditioning works perfectly and for as long as the journey lasts, no matter the time or distance. As soon as I stop and then restart the engine the air conditioning blows warm, if I keep switching the air conditioning on and off it will eventually restart, sometimes quite quickly and sometimes it takes a long time, when it does come back on it works perfectly. Any advice would be greatly appreciated.

Could this be a wiring/earthing issue? Might be worth asking an auto electrician to take a look

Glad you got sorted 🙂

You're welcome 🙂 please keep us posted on how you get on

I got both the hubs and bearing kit from ebay with the bearing kit £17.50 ea included both bolts from carpartsinmotion they had good feedback and the hubs purely on price 2 front for £50 from brillbuyuk although they have good feedback

I agree a second opinion would be worthwhile, however I think you will be very lucky to win a warranty claim on a six year old car.

Aircon compressor could be at fault. Has the system been pressure tested?

Keep us posted on how you get on
