My 2.5TDI consistently shows 1.5mpg worse than the real figure. The real figure varies between 28mpg and 37 (the latter on cruise control on motorway).

I've managed to watch the system with Vag-Com while it was giving trouble. The fault showed up for the first time with no extra load in the car. A possible link - last week it had four new tyres fitted, so it was jacked up (in jacking mode) and all four suspension legs dropped to maximum...

If you work the lock repeatedly with the key, the problem may go away for a while - it did for me.

however the new lock is around 90 pounds plus VAT. To get to it, you need to remove the door trim, the window assembly, then the lock. You need two different sizes of Torx tool, one for the window, another for the lock. The switch might be replaceable, but I hadn't got the tool necessary...

a stone trapped between the brake disk and the backing shield? Caliper (are they floating) sticking, so one pad rubs on the disk?

What are the ride height indicators showing when you first switch on with the suspension dropped? I'm wondering whether one or both of the front sensors has stuck in a high position, and the car is trying to correct it. However if that's the case, the car won't pump back up properly. If...

More info. I tried putting some weight into the back. Changing ride height upwards took between one and two minutes per step. If it was over around 90 seconds, the error light came on. Switching ignition off cleared the error. Repeatable several times. Took the load out - no errors. Drove...

I've got an intermittent problem with the ride-height system. Occasionally the dashboard indicator comes on steady, and the manual controls are disabled. Switching off the ignition resets it, for a while. I can sometimes cause this event as follows: Put a 50kilo load in the boot. With the...

The car spent half-term at a specialist Audi-VW shop. The only thing that came up consistently on the diags was "drivers door deadlock" fault, so he changed the door lock. After a week of use, there doesn't seem to be a problem any more. He also changed the tailgate lock as the rear...

Haven't found anything yet. What is is not: not damaged wiring in the driver's door. I've inspected it all, and unplugged most of it - I can't get the plug off the door lock itself, or remove the window mechanism to get to the door lock. There's a special screw I don't have a tool for. It...

As I almost never use the key, only the fob, the lock could be the problem. I'll do some experimenting with the key behaviour. Thanks for the suggestions folks.

Could be - Bosch would make sense. I'll try the connectors, and also the fuses - intermittent power might cause this sort of behaviour. There's a heck of a lot of connectors between the two front footwells. The central locking is electrical, not air, so no pump. Apparently the immobiliser is...

The saga continues. The local specialist garage agreed with your suggestion - water in the comfort ECU located under the carpet in the front passenger footwell. I stripped out the foortwell side panel and carpet, and discovered no water, and no evidence that there had ever been water. Opening...

My previous car was a 14 year-old 100 2.8 quattro. The clutch failed at 200,000 miles. I think the problem was a broken pedal due to a sticking mechanism (the same fault I had with a 100 Avant 15 years previously) but because somebody kindly wrote it off while parked, I didn't have to replace...

Interesting thread. I switched from a 100 2.8 petrol quattro to an Allroad 180bhp tdi a few months ago. My initial impression was of difficulty taking off smoothly and quickly in 1st, and of being unsure of the correct gear most of the time when under 40mph. Those impressions have gone. It takes...
