Ok guys been on several forums looking for answers found some good input but still having issues also stay with me New to the forum first time posting!
Ok first info on car
2002 alh tdi 5 speed golf fmic and all upgraded piping, egr delete, injectors, catless downpipe, 2.5 straight pipe exhaust, apt stage 1 tune, south bend clutch.
I bought the car at 140k miles and currently sits at 190k
The turbo has had a slow oil leak for a while so I ordered a new vnt15 turbo, just before the Install I ordered a boost gague and put it in. Old turbo would spike to 20psi and hold 10psi.
Then I installed the new turbo and had no boost upon further inspection and checking on the forums realized since I have egr delete I could delete n236, n18, vacuum resivor and all associated vac lines. After deleting it all I got boost back! But was still spiking 20 and holding 10...
I removed all Intercooler hoses cleaned them well and boost leak tested it and it held 30psi.
First test drive was better spiked 20 help about 12-13. So I took my old n18 and swapped it for the n75 and would hold 15 psi consistently.... so I bought a new n75 and now I get 26 psi and over boost code... so i got a hand help vac pump to test the actuator and it was in adjustment started to move about 4 inch pounds and hit the stop about 19 inch pounds. After more research saw a lot of other guys having trouble with map sensor so I ordered one and install with no change. This is where I'm at right now.... throws over boost code and goes into limp mode. In the morning I am picking up new maf sensor and putting it on and that's the last thing I can think of.....
Sadly I do not have vac com
If maf doesn't work where should I look next!?!?! Please help
