My Audi 2.5tdi 101K miles has today developed a stalling problem. When the engine is idling, the car will stall after a few seconds. It happens about 30% of the time and occurs in any gear, N, D, P, or R.

I have now been able to put VAG COM on the car and it shows 2 faults.
00575 - Intake manifold pressure 08-10 - control limit surpassed - intermitent
17583 - pre injection turned off P1175 - 35-10 intermitent.
The following day, the car started and then won't start. Following fault was found.

01126 Engine speed signal
16-10 Signal outside specification - Intermittent
Fault codes cleared but the engine still doesn't start.
Does anyone know what needs replacing

Seems to me that the speed sensor died while the engine was running causing the car to throw the 00575 and 17583 codes. Take a look at those in the Ross-Tech Wiki (link below) and you should get some idea what was going on.

If the engine controller cannot see a valid signal from the crank sensor, then engine is prevented from starting. I'd be looking at the sensor and it's wiring as the starting place.<ul><li><a href="http://wiki.ross-tech.com/index.php/Category:Fault_Codes">http://wiki.ross-tech.com/index.php/Category:Fault_Codes</a</li></ul>
