    White smoke is water, blue smoke is oil, black smoke is fuel.

    Have you had the car scanned? It could be the temp sender making the car think it's cold out and there for on choke as it were all the time, or a failing MAF making it think more air is passing and sticking more fuel in to compansate.

    Without codes or anything it's hard to say

    Yes i've had vag com on it.

    I've got a eml on because its got a decat asI am getting a stage2 map next week and also it said about my temp sensor and possible thermostat but i changed the two last month

    Could it be a faulty sensor or thermostat because im sure i didnt have them codes before,but then again i didnt check it with vagcom before it was just with a scanner.

    How could i check the maf?


    Converted to English

    If the temp on the dash is correct at 90 degress then the stat is working correctly.

    Was the temp sender a genuine one? As it has been noted that pattern ones are not so good.

    You need VAGcom to log the MAF reading as the scanner will not be able to do it at all
