Any ideas? i'm goin to check the wiring to the N75 when i go to work tomorrow, but i'm not sure about the "Adaption Limit exceeded" one. not long replaced my lambda sensor so that rules that out pretty much, and the MAF was replaced about 2 months ago aswell.

Any help would be greatly appreciated,

Cheers

Forgot to mention the car is back to standard map with K03 fitted, and standard injectors. the 4 bar fuel pump and FPR are still in place.
 
Sounds like a faulty n75, check the connector and loom leading upto it. You should still be able to drive it though
 
Thank you mate, will be having a look tomorrow as i cant get back into the workshop....
Yeah it still drives, just in soft limp, so it would be a long boring drive back to Scotland haha!

Cheers,
Robbo

Right, had a look this morning, both of the wires are snapped off just inside the connector. (thanks Sportstractor) will fix this at work.

Still worried about this one though -
00561 - Mixture Adaptation
14-00 - Adaptation Limit (Add) Exceeded

i think i'll check the flow rate of the pump, but does anybody have any graphs for the flow vs time graph for a 4 bar pump?

Cheers

That's probably just a fault that's been caused from faulty n75 not regulating boost correctly, I would repair that then clear it.... You would be quite unlucky to have 2 separate problems

on std map but still with 4bar regulator?
why is this?

3bar is what would be on std map

if the block 032 is 25% positive it would suggest an airleak prelambda or perhaps also an under reading maf...
 
yeah because i dont have any other FPR's lying about over here. just did a WOT second gear run, and the maf is reading correctly. checked the downpipe and it was fine aswell. will check the head-manifold bolts tomorrow...

fixed the wire and took it for a drive, and it felt like the turbo was surging. cleared the fault and all is good, just dont have enough time to take it for a long run tonight though. so i'll check that tomorrow night when i give my mate a lift to Hannover. thanks for your help everybody.

Riteo.. checked everything head back, and no leaks. tried my mates spare MAF sensor (was still in the box) and no diference... no surging but now feels like the engine is hitting a flat spot @ 3500 rpm and then goes back to normal @ 4500 rpm. feels like the turbo is running out of puff but the boost remains the same.... Badger do you think the 4 bar FPR could be causing this?

Cheers

Robbo
 
It will be running at least 15% too rich , so the ECU wil need to pull that back out assuming your current setup is running at zero correction. I would say it's that 4 bar fpr causing the fueling errors. Overfueling/ rich mixture can have the effect of reducing power output.
 
thanks :) just wish i had a 3 bar laying about here to stick in it for a test run,

Thanks again

Robbo
 
indeed, i'll get the 3 bar one fitted as soon as im back, just in the process of asking around for a full version of vagcom just now. nobody in my area appears to have it, there all cheap a*se's like me haha!
 
right changed the FPR back to a 3 bar one, and im still getting this flatspot between 3500 and 4500 rpm.... any ideas?

Cheers

Robbo
 
i unplugged the MAF and it ran fine, had a bit of a brainwave yesterday and put my standard MAF housing back on and all is back to normal :)

Cheers for all the help guys :D
