Common A4 faults

[Rickky]

Hello, can anyone share their experience of owning a A4 b6 and what type of common problems the car has, ie is the timing belt an issue with many of you or Automatic transmission, Heated sets etc.

Hi Richard, I noticed your post, and having recently bought an Audi A4 b6 1.9 tdi. I thought I would take a peek and find out what might be in store for me in the future. However, looks like I am the first to respond.

The only thing I might be able to shed some light on is the TD engine, my previous car was a VW Passat with the same engine. Although the timing belt lasted, I had problems with the tensioner, which on one occasion de-tensioned, fortunately it was slow and the engine just slowly misfired into a stall.

On another occasion, the bracket that holds some sort of spring loaded pin to give more tension to the belt failed. Fortunately, I was going about 5 mph over a speed bump in a country park, so no damage to the engine. and the car went on to cover 240,000 miles before I wrote it off in a crash. But they do seem to be bullet proof.

The A4 I have now has done 149,000 miles, but the previous owner has spent a fortune on the suspension and front sub frame replacement. However, He did live by the sea and that might be one reason for this.

One issue I have is the temp gauge never seems to read correctly, unless the outside temp is 25 degrees. It was exactly the same on the Passat. which had the temp sender at the back of the engine replaced with no difference. I had the same changed, and the thermostat on the A4. All was good for about a month, now it's back to previous indications.

Hi Rikky, sorry,I just noticed your A4 is a 1.8, and I have been 'banging on' about the 1.9 tdi PD engine.
