    Instead of smashing it up you could take it somewhere to have the codes read, which would tell you why the EML is on.

    If this was a symptom on a BMW (the engines I know very well), the first place to check would be the Idle Air Control Valve - these get coked up and often need a clean out with a bit of carb cleaner.I assume the 2.5TDI has one so I'd suggest that.

    I'm new to this forum I'm usually over at the a3/s3 but that's now sold, usually 1 or more coilpack has gone which causes the engine to miss fire and rumble on idle, but unsure if your car has any if it does then I'm sure it's that
