Evening all
Ive had this fault code come up
17965 - Charge Pressure Control: Positive Deviation
P1557 - 35-10 - - - Intermittent
Seat Leon 1.9 TDi 110 (ASV engine) with a pd130 turbo
I searched and found lots of info, but couldnt find anything like what im getting, so this is why im posting
Basically when the oil temp is like reasonable temp like 70-90c the turbo doesnt overboost high, will overboost to like 23psi and drop down to 20psi, but the more i give it a thrashing, keeping racing, on private road of course lol, the hotter the oil gets on the gauge, the more it overboosts and holds overboost for longer during gear changes, when the oil is very hot i have seen the overboost spike to something ridiculous like 35psi when the oil is like 120c and it holds so i have to take my foot off the throttle, then after a while of thrashing and its overboosting it will chuck it in limp mode, but its weird, the hotter the engine gets the higher it overboosts if you get me, could this be because i have a side mount still, if i get a fmic will this keep the oil temps down and stop the turbo overboosting mega like this?
any help much appreciated
