Vag com fault code, New MAF logs post 17/18

[r8byb]

17535 P1127 Long Term Fuel Trim mult.,Bank1 System too Rich

car goes into limp mode, then after a few hours driving or so it will give me boost back but EML will stay on... read the code and only fault code that came up was 17535 as above ? So any idea's guys, had it dioged earlier aswell and had boost deviation code aswell but cant remeber exact description, but since then its been running fine then had CEL bringing up above code...

So any help ? I only have trial version of VAG COM so can only log blocks 1 - 20

Cheers guys

Rob

[PhilW]

can you put it in CODE please.

 

[truCido]

** oops **

 

[r8byb]

Yeah foot was flat to the floor all the way through, i dont have a clue how to read it though, but i defo had it flat to the floor the whole way through.

and would intial surge not be where its spiking ?

 

[PhilW]

Crazy maf figures!

 

[r8byb]

we saying Duff MAF then ?

posted up the logs just to show its pretty much consistant over the two.

 

[truCido]

Possibly, those readings are rather erratic and would not give you a smooth ride! Do you know anyone else with a cupra? Could maybe borrow their MAF to make sure

 

[DPJ]

That MAF needs exchanging for a good one.

 

[ibizacupra]

you have'nt answered the previous question chap.
WHATS THE PART NUMBER OF YOUR MAF SENSOR ELEMENT?

not the housing, the element inside.

MAF readings are simply wrong.. so until thats fixed... your on a highway to nowhere

 

[r8byb]

Im sorry but i have absolutly no idea of how to take the maf apart, ill try and work it out tomorrow.

car feels pretty smooth though slight dip around 4.5k ish i think.

Also it does really throw you back like someone says then kind of dies off, but ive been told thats purely cause im running high boost on a ko3

 

[ibizacupra]

2 x screws holding sensor into top of the housing. security type tho.. on top of sensor where connector plugs in.. easy to find.

regards
bill

 

[r8byb]

Right ill look right now 2 secs ...

 

[r8byb]

right im in my bonnet now lol

its a bosch MAF part number 0280 218 032

hope that helps ?

 

[r8byb]

Right thats just the casing sorry the part number above, i know the MAF is from eurocarparts but i dont have the part number cause i have no torx bits. might just get a new genuine MAF :|

AM i right in thinking log in third gear looks ok, just slightly low reading 148g/s for stage 2...

But then others are all over the place, it was raining that night and we kept hitting puddles which obviously sloed the car down a bit but i kept foot to floor.

Cheers
