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...
