I had an issue with the car today, and wondering if anyone could give me a clue as to what it might be.
I was driving up the motorway and when accelerating to overtake the 'Engine Malfunction' message came up on the display. I stopped and switched off and the message cleared. I continued and again under acceleration the message came back. I stopped again, and again it cleared.
When I set off this time I could hear a loud whooshing sound, like there is an air leak in a hose somewhere. When I got home I took off all the air intake hoses to and from the turbo expecting to find a split, but nothing.
The car is maybe a bit down on power when this happens, but only a bit, and no other symptoms.
Any idea what it could be? I was thinking maybe a split or leaking intercooler, but it looked ok earlier from a visual inspection.
My car is a 2008 1.8tdci .
Any ideas will be welcome.
