Looks great 👍

I'd recommend you keep it if you can. I think you'll regret selling it.

You're welcome. Sorry autologics couldn't help you.

Could be caused by a seized piston in the brake caliper causing the brake pad to be rubbing on the brake disc when brakes aren't applied. Definitely worth getting this checked out.

Glad you got sorted 🙂

I'd definitely be making a complaint especially as you've paid for the update.

No probs. Please keep us posted on how you get on 🙂

Glad you got sorted 🙂 glad you had a lucky escape with that leaking fuel line.

Sorry to hear your selling up. Lovely car.

Id recommend a diagnostic check to see if any fault codes flag up. When was the gearbox oil.last changed as this can affect the gearbox changing gears. Yea you could try a software update on the gearbox or needing a new sensor. Worst case scenario it's the module that may have failed.

Hi Andrew please could you give us more information? Power loss could be caused by various reasons such as failing turbos, injectors or maf sensors etc.

Yea it'll need to be coded. You might find you'll need the code for the new unit too.

I'm glad you've narrowed it down. My advice is to remove the scuttle panel completely to gain better access.

Could be a sensor or an issue with the heater control system.

Please keep us posted on how you get on 🙂

If it's a disc or SD card you might be able to get one from eBay.

I have a 2002 A6 c5 2.5tdi with 344k on the clock and thought I'd do a buyer's guide. My A6 has full service history and I'm the second owner. My dad being the first owner. The engine and gearbox have never been rebuilt. What's the service history of the car? Check when Cambelt and water pump was last changed.asbrgis is a front of the car off job. Should be done at least every 8 years. Do all electrical items work? AC compressors can fail and they're expensive to fix. The central LCD screen pixels are known to fail but these can be replaced for around £300 roughly. Also I appreciate Spain doesn't get as much rain as the UK but water ingress culprits include the pollen filter housing and the battery tray which is located on the scuttle panel. The tray fills with leaves etc blocking the drains. These spots let water in and flood the comfort control module situated under the carpet (passenger side in rhd cars). The CCM failing can cause all sorts of electrical gremlins. And has to be replaced with a part with identical part number. If an auto and a CVT make sure it changes smoothly as these gearboxes are prone to failing. Make sure it's been serviced. Slow starting can be caused by failing glowplugs. I can confirm this engine can start with only 3 glowplugs working! As I found out. Smokey exhausts can be caused by leaking injector seals. Headlight switches have been known to catch fire and I believe there was a recall for this however facelift cars should be fine. I personally am finding it hard to source interior trim. You might have more look in LHD. As with any diesel the turbo can fail and they can whine. My car has had 2 turbo's in it's 20 year 344k life. The first turbo failed at just over 70k. These engines do have egr valves. These valves are known to fail on modern diesels but In my case (fingers crossed) it's still on its original egr valve. Knocking noises from the front can be engine mounts. Also on the front suspension arms are known to go. Bodywork issues are the top of the front arch lips due to the cars having a piece of foam on the inside which obviously absorbs moisture and causes the wings to rot, and bubble all round the arch edge. Also check lower does where the lower door trim is as rust can form under this trim. You'll know if you look on the inside of the door in the corner. Also l the headlights may have been affected by the sun and gone cloudy. Over all they're great cars I still use mine for road trips around the UK and Europe. It's due to go to Norway and the arctic circle in August 2023! On the whole it's been reliable despite going round the nurburgring, drag strip at Santa Pod plus maxing it on the autobahn. Obviously I've mentioned some issues, of which I've had a few of the ones listed. A lot of people slag off the 2.5tdi as being unreliable, however I believe the unreliability comes from a lack of good maintenance and poor servicing. Mines over serviced to be honest but I want it to be on best form.as possible and for my peace on road trips. Just remember the car might be cheap to buy but no matter how old an Audi gets the bills remain high. Oh and don't forget to check out the A6 c5 section on this forum as it'll give you further helpful advice 🙂

Welcome to the forum you'll find the members on here are a friendly and helpful bunch 🙂 Bumper fitment will also depend on the spec of your car. Such as se, s line etc.

No probs at all. Please keep us posted on how you get on

Glad you got sorted 🙂

You're most welcome, 21 years of c5s you get to know all the ins and Outs. It could be a tiptronic gearbox which aren't as bad. Just make sure the gears change smoothly and that the gearbox has been serviced. I bet it's a final edition model too being a 2005 c5. As such mdke sure the satnav works. It'll be the RNS-E version. With the high mileage I'd like to think it's been very well maintained.

I'd highly recommend you speak to the company who fitted the ghost alarm. If you hadn't mentioned the ghost alarm I would have suggested the factory fitted immobiliser as the potential culprit. Have you had a diagnostic check to see if any fault codes flag up?
