sounds to me like a scam why didn't they get a printout of the fault code for proof that its the turbo ( which I doubt there's a problem )? no light on now suggests to me it was a bogus fault but it should still have a soft error code stored in the ECU ask them to diagnose it again and ask for a readout, its an old cash trick by garages like the EGR valve needs changing when they know it can be cleaned so it comes down to cost :lol:
