    Hi Everyone,

    I hope you can help me.

    I've had an ongoing issue which has the following symptoms:

    Hesitance in acceleration specifically between 1500 - 2200RPM
    When sat at 70MPH on the motorway and around 2000RPM, a
    pulsing sound from the exhaust
    Black smoke when accelerating hard

    I have replaced a number of things....EGR valve, MAF sensor and have had all hoses checked for leaks.

    However, I have recently happened across forum discussions about ECU software updates and also that hesitance between 1500 - 2200RPM is a common problem on the TDI engine and can be addressed by a software update that amends the EGR values.

    Does anyone have experience of the above or can tell me which is the newest version of ECU s/ware for the 2.0TDI (140bhp) BRE engine?

    Many thanks in anticipation...

    Many thanks,

    I also have a lot of black smoke under 2k while the car is on load. I was also wondering if there are any software updates. I contact audi UK and if there are updates im going to update it and then map out the EGR because I know they can cause head ache's
