    Question Data Interpretation Help, MAF & Boost

    All, I have a strange problem with my 2007 A6 2.0 TDI 140 -

    at about 1900 rpm the engine becomes extremely lumpy. when it reaches 2000 rpm the engine runs fine. This happens when revving the engine stationary and when driving.
    The car idles smoothly.

    My friend used his vagcom to do some logging for me last night however I am having a few problems interpreting the results.

    I have logged channels 3 & 11 of the engine, for MAF and Boost Pressure.

    Would some one be able to take a look to see if there is a boost leak or maf problem.

    Many Thanks, your help is appreciated.

    Please PM me your email and i will forward the excel workbook.... untill i can work out where to host the file and post a link
