Hello all.
My lovely a2 (1.4 petrol aua engine) start to give problems again As usual the problem fells like misfire between 1500 rpm and 2100 rpm.
This time vag com scan say error:
17961 - Barometric / Manifold Pressure Signals P1553 - 35-10 - Implausible Correlation.
But this time i found something strange when doing the vag com diagnostic. In group 11 measuring blocks the intake air temperature for the engine is not correctly readett. Its saying 66C 70C degrees. But the outside air temperature was max 31C degrees.
So now the big question ,is the air intake temperature for the engine given from the MAP sensor ? My manual say that we have too sensors one G42 and G71 ,but im thinking they are combined ?
As usual i chek for intake exaus leaks - all fine.
New spark plugs.
Egr valve clean reseted.
Thotle body clean and reseted.
Engine earth points clean as new.
Any help will be appreciated!!
