So over the past couple months when driving on the highway I would notice that sometimes my car would lose all power and slowly coast to a stop, but then the power comes back on and I'm off after a few seconds. It happened again today and I notice when I do hit the gas when it decides not to accelerate my boost gauge shows that there is vacuum building up in the engine. It just doesn't make sense to me. Would my car be getting thrown into a limp mode? Or is it something to do with fueling?

About three nights ago I had a complete power loss on the highway and the car began to bog down alot under throttle (and surge at points as well although with no boost). It also idled very rough/erratically. When I unplugged the MAF it cleared up right away; Idle was smooth and it ran without hiccup but in safe/limp mode so very tame (again, without boost really, gauge shows it stays in Vacuum and never passes "0" or goes into boost).
I scanned it this evening and got 2 misfire codes and a MAF code, along with a code related to traction control which I noticed had activated as a result of this and could not be turned on (by activated, I mean the light came on, disengaging T/C). These things make me think it is MAF related, especially because I have bolt down Hitachi coil packs so I do not think that is what it could be in relation to the misfire codes (which I think may be old and needed to be cleared).
Fast forward to last night: I can pretty confidently say my MAF is not the problem and I think I saved an unnecessary expenditure. I was able to meet a friend with a 337 as well and his MAF did not change my car at all and my MAF ran fine in his car so I think my problems are something else. Although with the MAF plugged in my car runs very poor and unplugged it clears up and just runs "limp" (no boost and slow but stable) from what I tested this evening the MAF unit seems to not be the issue.
I think there must be a vacuum leak of some sort between the MAF and the engine which allows more air in than the MAF signals when plugged in which causes the issue. Also, I know a common thing to think is "coilpacks" but I have bolt down Hitachi coil packs so I would imagine that would eliminate those from being the failure they tend to normally be. Agreed ??
GTI 337/20th Anniversary :: Secondary Air Pump That Turns On When Start
I have a question? I have had my car parked for about 2 1/2 months and I just started it this weekend and I've always noticed on our cars when we start them in the morning I think it's the secondary air pump that turns on, it sounds like a blow dryer.. It only stays on for about 10 seconds maybe. Cause when I started my car this weekend I didn't hear come on.

A buddy of mine has a gti that is not starting. he said the temp light has been coming on and the car would start to struggle. of course he kept driving. Today it came on and stalled out. Now the car turns over but wont start. I replaced the temp sensor (green plug) and it wasn't the issue. its a 1.8t with 80k on it. 2002. I am assuming its got to be fuel or spark.

I've had the car about 3 months now. It runs fine, never overheats, but I keep having to add coolant (every 2 weeks or so), but I can't see a leak anywhere.
I searched and found one guy that said it could be a bad expansion tank cap, and another that said it could be a tiny leak that only leaks when driving.
Anyway, when replacing my axle, I noticed this:
If that's dried coolant, where would that be from?

I have a 2005 mkiv GLI and my gas gauge, temp gauge, and information display stopped working when the car is running. They work when the car is on auxiliary but not while it's running. The lights all work on the cluster all the time but the needles don't move as soon as the car turns on.

My 04 gli makes a rubbing noise when accelerating thru hard left turns.. but weird enough i can take the same turn at the same speed in neutral and have no noise at all. I changed both front wheel bearings and cant seem to find the answer. I brought it to vw and they checked the whole suspension struts springs cv's tie rods ect. and they all checked out good they said. the car used to have a exhaust and i just recently put it back to stock, could the exhaust make the noise perhaps?

I replaced all 4 and im still having the same problem...
