Sorry to ask a seemingly repetitive question but I'm starting to run out of ideas here...sometimes i get limp mode, other times its just low power but not limp mode. Ive been working on this for almost a year now. first i looked at the vnt actuator. when i pulled it off and moved it by hand a bunch of rust came out so i replaced it. it ran better, then the turbo itself went. i replaced it with a vnt17, replaced the vacuum lines, cleaned the intake, and disconnected the vacuum line to the egr and capped it (surprisingly no check engine light). it ran awesome, then about 4 months later i had this low power/limp thing going on again. i unplugged the maf and went for a drive and it hauled a$$. so i replaced the maf. it still had low power. then i replaced the n75 valve, fuel filter, and cleaned out the fuel canister in the tank. no change. it doesn't spool til around 3000rpm and it doesn't make anywhere near the boost it did when i first put the vnt17 on and if i hold boost like on a hill or hard accel it goes into limp mode. it has never thrown a check engine light for anything since I've owned it and yes the bulb works. the car is a 99.5 jetta manual trans. im running a stg2 rocketchip and pp520 injectors, its straight piped so it doesnt have a clogged cat or anything. and ive read about all i can on limp mode fixes on just about every site out there and ive spent more money on limp mode stuff (if you count the new turbo) than i did on the whole car. any ideas would be appreciated because I'm out of them.
