    New head needed I'd say, you'll lose compression/burn oil


    Update on mine regarding hot start - had it remapped with hot start fix and all has been good since (same starter & battery that was advised to be replaced - they don't)

    I think the 'P' will be a 'B'. You may have misread it ! Mine is an 05 plate but 06 MY like yours and mine is a 'B'

    After reading this I've gone out in the rain to check mine...

    Mine is a 55 plate... but has a C head.... does this possibly mean the head has been replaced at some point?

    Brought a 53 plate 2.0 TDI and the part appears to have been replaced:03G 103 308 C although I have the warm start issue which is becoming annoying.

    Just got round to checking mine. Appears to end in an A and has done 120k with no problems.

    Has anybody any experience of them suddenly going at higher mileages? Or at 11years and 120k miles is it at the point where it would have cracked if it was going to?
