Audi A4 2.0 tdi 140 Turbo/engine light issue
I am new to this so I am sorry if I have put this in the wrong area.
I have a 2006 audi A4 2.0 TDI 140 S Line, driving to work this morning the Turbo decided to not work after 10 mins so I turned the engine off and re-started went fine for 10 mins then the engine management light came on and no turbo I have had this car less than 6 months, absolutely love this car but I am unsure what the issue is, no white smoke coming out the back end so I know the Turbo hasn't gone (Previous experience on a Mazda 6 Turbo blew) what could it be??
Much appriciated if you can help me its booked in on Monday I would like to pre empt hat the issue is before hand :)
