I am having issues with my A4 2.0 TDI 170.
The car feels under powered and not overly prompt on starting. Low revs are a real struggle. It is an 07 plate and has just hit 86K.
On a reasonably fast motorway run for 2 hours I am hitting around 34 mpg (a little low)
On occasion the idle is erratic too.
I have been asking around and a few people suggested that my injectors may be blocked. After several months now of various diesel injector cleaners I am seeing no results.
I asked around some more and have read a few forums and the diagnosis maybe the MAF.
Before I spend money to change this, does anyone have any suggestions for cleaning them or is it not worth it?
Are there any other things i should be looking out for?
