Hello all. I'm reaching out because after extensive research via these forums, I'm at a point where I need assistance. Here is what's happening with my wife's 2005 2.0L (BEV) new beetle. The car started experiencing stalling issues once the weather got hot (88-100 degrees F), and the a/c was...

I have had my bug for about a year now and I just started having a problem with stalling and idling. About 2 weeks ago I started having a rough idle and it would stall while going around turns or at low speeds. I though it was the maf going bad. While driving on the highway it started to loose...

Alright so I am back once again with trying to get my 2.0 running and I have made a little headway but it seems not by much :( After doing what seems like a lot (which doesn't honestly seem like too much) I am at a complete standstill and almost want to quit and sell the thing. Things done so...

I bought my car (2001 GLS 2_0) last October. I love this car! :nblove: The mileage was a little over 25 k. There was a sticker on it for servicing in 5K. It's a little over 29 now. So, last night my check engine light came on. The hubs checked the oil and it was wayyyy dry. (Yes, got the...

I have a '99 New Beetle 4 cal 2.0 Eng, manual transmission, that has been having a lot of problems lately. I've gone to a mechanic and tomorrow will be my fifth time dropping my car off at this particular shop. The issue I've been having is a rough idle among other things. The things that...

My wife's beetle was running very rough and throwing misfire codes, I found a detached tube, which I think is a breather tube. It has ECS on the side, and seems to have melted apart. It seems to slip into a heat shrink like tube. Once I did that, the car runs smoothly (although that tube is...

It's been a LONG time since I have been on the board but, as always, I come here to search the board when I have 'issues'. Since the whole timing belt and bent valves mess the bug has had cold start troubles as well as idling issues. When I am sitting at a light my boost WAS at -20 but the last...
