Title: Flat Spot When warm - MK4 GTTDI
Post by: archie837 on 19 June 2012, 15:54
Hello! Had a quick search but nothing.

When the car is not up to temperature, it pulls absoloutely fine through the revs and onto boost - roughly 2k.

When up to temperature though it has little pull until it is on boost - massive flat spots - I can compensate it by slipping the clutch and keeping the revs higher onto the boost, but not ideal.

Is this potentially a gummed up MAF not reading right? Would've thought it would be doing it all the time if so.

Cheers in advance!

MAF almost 100%. Try a known serviceable MAF before getting a new one though. :afro:

Errrr, alright mate. Whatever!  :rolleyes: :grin:

A new MAF will set you back £80~ from GSF incase you did not know. Alot of money for something so small  :sick:

Aye cheers for that. Have got trade at ECP so hopefully a bit better.

GTTDI's prefer the Bosch MAF IIRC?
