    Hi guys and gals,

    Last few weeks I've been getting a nasty cold start, very lumpy and up and down the revs. Also, with a bit of lumpiness until it reaches full temp. Initial thought was cts so just changed that now. Still slightly lumpy after changing it. Stuck in code reader and got 16705 which seems to be the engine speed sensor, so ill look at getting that changed but also got 16486 and I can't seems o find anything about that apart from on passat w8's! Which seems to relate to some kind of sludge build up problems or related to misfire issues.



    anyone had this, or similar? Would be really grateful for any advice.

    Cheers,

    Matt
