Hello, I have recently purchased an 04 Audi A6 3.0 TDI Quattro S Line and have started to experience problems that led me to this site. When the car is running idle whether in D or P, the engine has started to stall. When the car is driving it is going 100%, however when stopped at junctions it is likely to stall. I put the computer on it to get the following code;
17471 Fuel Pressure Regulation: Control Range Not Reached: P1063

I was quoted £240 for the necessary sensor but was told this may not even solve the problem. Has anyone encountered a similar problem and how was it solved? This is my first time using the site so thanks for any help.

 

exactly the same thing is happening to my 2005 3.0 tdi quattro bmk engine code. i get the same erorr code 17471. the mechanic told me to replace the fuel pressure regulator but may not solve the problem. how did u solve it. thank you

 

I was told it could be bad diesel. Before replacing any parts which were all going to cost a fortune I ended up driving all the diesel out of the car and put £10s worth in again and did this a few times. This seemed to work as it hasn't stalled again since. The fuel sensors must be very sensitive.
