dom86
hi guys ? a lot that I do not write asking for help I have a audi a 4 2500 tdi v6 smokes cm crazy, but I agree with pulling the legs that cannot walk seems to be sucked in the diagnosis of mi from the flow meter replaced, but nn is the same then arrived at around 3000 rpm's hitting but exceeding 3000 rpm it stops can you help me?

make sure to check all the intercooler pipes and the intercooler itself that are not slotted.

dom86
already done but nothing in sight they all seem to be ok

ugoboss
if you are sure of the air intake system, attacking a good diagnosis and begins to control all the parameters, including egr that is stuck open.

Also check the turbo boost pressure detected in the diagnosis.. cos? you understand if you have some sleeve broken..

make sure to check the mancotti you may have pressure loss....even if it usually is the presence of error in the ecu.....

dom86
the only error that it gave me was the mass air flow sensor

dom86
then the car before reaching the 3000 rpm beats

ugoboss
what does it mean to "beat" have you checked the egr.

dom86
then the car before reaching the 3000 rpm beats

dom86
you ? tapped cn a sheet and ? deleted from the ecu

legendaryslave
check if you move the geometry usually breaks the wast gate

you have the egr does not close then clean it ,replace it or disable it from the map and solve the problem.

I had the same problem with an Audi a6. It was the turbine route .

dom86
fixed there was a lack of communication between the mass air flow sensor and the ecu pump

considering that this is a very fair response
