guys my cars has suddenly become completely guttless i have no power and it sounds like a fire engine ive tried a few things the vanes were stuck so sorted that i have had the boost pipes of no turbo damage or play ive changed the boost valve to still the same so this morning i unplugged the maf while it was running and it made no difference at all idles the same drives the same (guttless) so in my eyes its all pointing to the maf? can anyone confirm this
If you have vag-com take a log of mesauring block 8. See whether the smoke limiter is less than the rest...
Long time no see I had similar on a PD115 Alhambra, that was the MAF. If you don't have the tackle to scan it, try here: http://www.clubgti.com/showthread.php?275495-Welcome-to-the-cgti-kent-forum&highlight=
ordered a scanner so going to try that when it gets here its pretty useless as it stands i thought my days of turbo golfs was long gone but having bought the gttdi ive had nothing but issues gluton for punishment me lol
My passat lost a lot of power i found a vacuum pipe had come off just in front of battery.something to do With the fuel.2003 pd 130.
changed the maf and its still the same starting to think the new turbo cartridge i fitted is knackered
tried a few things tonight disconnected the vac line to the turbo and the fire engine sound is all but gone but still no boost or turbo spooling so thinking its the actuator
With No vacuum a VNT turbo'd car makes no boost so will be gutless. You "sounds like a fire engine" now makes sense to me. Sounds like your car is overboosting then underboosting. Sounds like your vanes are sticking. Try cleaning them with oven cleaner.
If it's the vanes in the turbo it will boost to start with then go into limp mode And will clear if restarted If it don't do the above it's not the vanes As ian said above the MAF would be my thinking as mine did the same You can check the measuring block for it in vag-com to see if it's duff
took turbo out and the shaft is bent and fins ground away not really sure whats gone on but new turbo ordered
pretty sure the oil feed is ok as it covered me in oil when i took it out i think i may have bent the shaft slightly whjen i changed the oil seal a few months back as when i fitted the turbo to the hot side i didnt locate it on the vanes pin by which time id wound it up ben tight before i noticed
new turbo fitted still no boost but i now also have a hard brake pedal now ive checked the servo pipe and it has no cracks and holds pressure ok vac pump is sucking nicely bit lost now very frustrating
