Unhappy A8 Glow plug light

Hello James

In the end i had to book my car into a main dealer,it was there for a week being diagnosed,in the end it was found that the ecu which drives the turbo had an intermitant electrical fault,the bad news was on the 04 and 05 model cars the ecu is part of the turbo,so i had to have the whole turbo replaced,dianostics,new turbo,one small sensor and the oil and filter changed cost me 1976.00
Was well pleased as you would expect,especially when i had only owned it for one month,i guess thats what you get when you buy from a specialist and not a main dealer,warranty would not cover it,audi said if i had bought from a main dealer it would have been covered

Sorry for the bad news
Regards Andy
