Engine Management light came on a week or so ago, car drives absolutely spot on.
Plugged it into my OBD cable, came up with error code "p1504", used the software to reset the codes. Driven it 300 faultless miles and it's come back on again!
I googled the error code and it says something about an air leak - I'm not particularly mechanically minded, I've visually inspected the engine bay but can see anything obvious.
What I was just wondering was, should I buy VAGCOM, would it give me a more specific error message?
Any help would be greatly appreciated!
