deviation

Ok lads, I was having the annoying 17536 (system too lean) problem for quite a while putting me into constant limp mode. Finally bought a new maf which cleared that problem. However I am still running limp, now due to 17965 (positive deviation or overboost as I read on here). This fault...

i am now thinking my charge pressure control negative deviation in 4th 5th gears under prolonged load could be map related, think map is requesting to much boost . Have checked everything vac lines,maf,new n75,and all boost hoses. its getting a bit annoying now the car goes well in 1st 2nd...

had remap done goin great just been out for drive and boost has dropped from 1.3 bar right down to .5 bar could it be standard dv

Took the cupra out this afternoon for the first time in weeks after fitting a miltek sports cat and downpipe , and fmic. At first when I took the car out it went well and hit around 15 psi. But when it did this I could hear a strange squealing/screaming noise ? Then the car would boost only...

Hello every1, Right long story short, my car goes into limp mode in 5th gear...50/60mph...foot down...5-10 seconds later boosts drops to 5psi, turn car off then back on it boost fine again. N75? what should i be expecting to see at full boost with my spec? only just...

Positive Deviation: PROBLEM FIXED! :) Hey, Just thought i would post up to say I have fixed my postive deviation problem finally thanks to the help of Simon_L on here who kindly did some logging on vag-com for me last night. As it turns out my brand new MAF from Seat was faulty and...

Hi, I'm getting this fault code on my car: 17965 - Charge Pressure Control: Positive Deviation P1557 - 35-10 - - - Intermittent Seat Leon 1.9 TDi 110 (ASV engine) When I'm travelling uphill mainly when the engine is cold at about 2500 to 3000rpm to turbo just cuts out...

My friends car recently has been plagued by errors and limp mode, in the 4th and 5th gears at WOT the car throws itself into limp mode every now and then. I did the N249 bypass last week which improved the car slightly, however theres still the negative boost error. Could this be down to a...

ok so itsover boosting STILL! it has standard mapping, ramair induction (with feed and silver casing off at the mo) and forge 007p ive tried maf, n75, coolant sensor, (cant see any leaks but...) what logs on vag com should i run? where should i look for a leak? dump valve is new...

I seem to keep getting this fault, especially when the air is very cold. Same story as usual, 4th gear, WOT, Around 5k. Hitting around 12psi, then limp mode. The car has been running really well recently however. Not had limp at all for weeks. Any suggestions? I really want to get...
