Hi everyone,
Ive recently picked up a 51 plate 3dr gti 1.8t and im having an issue and find myself wondering if any of you knowledgeable guys or girls can help, ill describe the issue below
Basically when i drive the car from cold it runs great it boosts well and is really quick, im lead to believe it has a stage 1 map at around 200 bhp which feels fairly accurate from the power, however everytime ive been driving for about 10 mins and car os well up to temp the power drops (to what feels like the standard 150bhp) . When i picked it up the eml was on giving code p0102 for maf sensor, i unplugged the maf during a power loss episode and it seemed to work for about a mile and then reverted back to low power. This morning i swapped out the maf and cone filter for the original airbox and maf setup that i got from a pal (unsure if this maf is a dud or not) upon starting this morning it took 5 attempts to keep it running so i jumped out, unplugged the maf which was still the old one at this point and it then idled ok and ran ok apart from the power loss half way to.work. then at work i swapped to the orinal airbox setup and when i left work it idled like crap again until i unplugged maf and then same as the morning, ran ok apart from power loss 10 mins into journey. When i got home.i scanned it and got p0102 and p0340 (camshaft sensor) i erased both faults then took it out for a few mile with maf plugged in but it still had not restored power but so far the codes have not come back so im at a bit of a loss wether to try a brand new maf or not, scratching my head a little now so hopefully i can get some.ideas to point me in the right direction. Or failing that find out if there is anyone local to swadlincote, derbyshire that might have vagcom that i could use to look a little deeper into the problem as i dont have it anymore.
Thanks in advance for any responses
Luke
