Steve Q Posted May 14, 2023 Share Posted May 14, 2023 I guess it depends how handy you are with the spanners. As I personally would always leave it to a professional. Have you done a diagnostic check to see if any fault codes flag up聽 Quote Link to comment Share on other sites More sharing options...
alpha omega Posted May 14, 2023 Author Share Posted May 14, 2023 hi steve, sorry i should have said.yes,and no fault codes i was just leaning towards injectors as i have high mileage.i have read on here people having faults with different things on their cars and not having any fault codes come up.i know its guess work without a reading.if i was to go down the rd of injectors then yes i will leave it to the professionals then as i am not that handy with spanners.regards stephen Quote Link to comment Share on other sites More sharing options...
Steve Q Posted May 15, 2023 Share Posted May 15, 2023 Is it smoking on start up?聽 I ask as mine was (before I blew it up) and I had a suspicion it was the injector seals that had failed.聽 No fault codes and she ran fine.聽 Quote Link to comment Share on other sites More sharing options...

alpha omega Posted May 21, 2023 Author Share Posted May 21, 2023 update put the car back together still 2500rpm at standstill took it for an italian tune up.it gave power when needed but no higher than just over 3000rpm still powerful enough but not the 4500 i used to have at standstill.still no codes.no warning lights on dashboard.i will have to look into what steve Q has mentioned the dpf as i have symptons of low power,bit of black smoke from exhaust,diesel fuel odour in the cabin,reduced fuel economy.i thought audi may have picked up on this on thursday the 18th of may as i asked for a health check on the engine. pleased audi realised about the timing though phew..

Love that, not heard the Italian tune term for a long time! Yea as I say I'd consider issue with dpf or even egr.聽 1 Quote Link to comment Share on other sites More sharing options...
