Audi A1 Sportback - AUDI A1 1.6TDI 105 BHP FAILS TO START OR RUN - BROADBEAN

Last week my year old A 1 1.6 TDI was running a bit lumpy on start up but eventually got going. I drove for about 25 miles before the car could not idle at traffic lights and stalled. I could not get thye car restarted and so called out Audi Assist. They checked the car and also were stumped as there were no fault codes and the system fuel pressure indicated no problems on diagnostics. The car was towed to Lomond Audi in Glasgow who carried out further investigations for a couple of days. They said that the car appeared all OK and even the EGR was fine. They were stumped and contacted the technical experts at Audi Technical advice centre. They decided to change all Injectors!!!!! Not sure why but a stab in the dark maybe. The car did start for them but is running really rough!!! They are now carrying out further tests to see if they can nail the fault. Any suggestions would be welcome as even Audi themselves are baffled by it.

Perhaps Audi should speak to their VW relation.There are known issues with diesel injectors on the 1.6 engine,some failing at as little mileage as 10k miles.Replacing all 4 should fix it,unless the engine has other faults.

I suppose contaminated / incorrect fuel has been ruled out ?

I've seen quite a few diesel's that have had petrol in them over the years and the symptoms sound the same : poor starting, roughness, idling issues etc.

Just double check with the dealers if they've ruled out the fuel, you never know ?
