2 days ago the check engine light came on whilst out of town, No on board errors showing. The engine was running normally and revving smoothly. I had lost the Turbo boost so no real power of the car, it drives well otherwise and is not making any noise from the engine or restricted in anyway/ Where I am located I dont have a Skoda or VW dealer for a few hundred miles. So I have to be self reliant to finding out the fault. My local mechanic is an old timer and does not do diagnostics or work on a computer. How can I diagnose what the exact fault could be. I feel its a sensor or relay which has stopped the turbo boost going back into the intake. I do not mind buying a OBDII with VAG tools, but would need some guidance of which unit that can pick up on this fault. As the links I have read dont mention Turbo as a fault they scan for!! Any help on diag tools is welcome or if anyone has already experienced this and knows the solution, advice welcome.. Thanks in Advance.
