[db666]

Could anybody help me with a problem with my A4 Avant Tdi. On acceleration usualy in low gear it judders for a few seconds before increasing its speed and pulling away. Any help would be greatly appreciated.

hi
i am having the same problem, i have an audi a4 2.0tdi s- line on a 55 plate, 77k its a manual and around 1-2000 rpm in second and third gear it gudders like the engine isnt getting fuel or something, i have tryed a new fuel filter and injector cleaner but none of these have worked yet, the only other things it might be is either the fuel pump or the tandem pump, or the egr valve, i have done a bit of research trying to find out what the problem could be, but you get a list as long as your arm,
any help would be greatful

Blb engine code by any chance?

B7 forum maybe better

yes mate
its a blb engine code, i have read that this is a common fault with the blb engine code.
is it the tandem pump that causes this problem? if it is the tandem pump is it likely to go again if i get it repaired
thanks
