I have a Skoda Fabia Scout 14 reg. A couple of weeks ago the glow plug warning light came on and the car dropped into limp mode. It went to the garage who did the diagnostics, fitted a new Turbocharger actuator, which cleared the fault. However, driving home the warning light reappeared, turbo not working and back in limp mode. Now the exhaust inspection light is on, it has been back to the garage again who confirm it does not have carbon build up, they have changed 2 x solenoid valves with no effect. I now have the car back, turbo not working, exhaust management light on permanently And running in limp mode. Garage have suggested I contact a vehicle electrician as it could be a wiring problem. Has anyone had a similar problem and if so, how was it resolved. I don’t have a lot of money for expensive repairs!
