    Hi guys, I have a 2009 Audi A3 1.9tdi PD105, engine code BLS. With DPF.

    my car has a large amount of smoke coming from the exhaust when at idle and when accelerating.
    The following has been replaced.

    -Turbo
    -Camshaft
    -EGR
    Uplift fuel pump (in tank).

    and still nowhere!!

    Got a fault code P0102 - MAF sensor circuit too low.

    Any help at all would be greatly appreciated.

    Thanks in advance.

    Only replace with a genuine Bosch unit.
    Why did you replace the other parts?

    Replaced the maf...not the maf!!

    I replaced the turbo because it was not boosting correctly, the cam shaft was replaced because of poor/failing to start, the camshaft was worn.
    The smoke is slightly blue but more grey, it is not excessively burning oil or anymore than it shoul, as I keep an eye on the oil level. The car is serviced correctly at the correct intervals so it is well looked after.

    i have been told a worn injector? Any ideas would be great, injector sounds poosible.

    thanks
