hi ,ive got a a4 tdi 99 model afn , theres no boost ,ive stripped turbo cleaned the vains so thats ok ,cars had a new maf ,its like in permanent limp mode does anyone have any ideas cheers !!

I dont know if this helps, but there should be a boost sensor somewhere in the induction pipework. Also, it may be a problem with the EGR valve being stuck open..
|
|
And a diag code read pointed to what. ? Regards Peter

it came up maf ,but its a new maf ,and a preasure regulator valve
|
Where did you get the maf - lots of fakes around.
What about the regulator valve? Replaced that?
I would be doing some careful checking of all the hoses.
