Title: Flat spot on 1.4TSI
Post by: crazy col on May 15, 2014, 10:20:51 pm

Hi all
My 1.4tsi has a flat spot when I accelerate, had it serviced last week but is still doing it, any ideas what it could be?
2006 1.4TSI with 69000mls
Thanks  :scared:

At what engine speed are you getting the flat spot?

is it when you get to around 3500rpm?
If so I had the same problem, and I replaced both N75 control valve and N249 (Diverter Valve) and all was sorted.

I have the 170 model, but it should still sort the problem on the other model.
