Two questions rolled into one post. First, what do you feel is the best chip for a 00 jetta vr6. Please, please include why.

Second. When my jetta is at idle, the lights kinda flicker a little. 2 or so times a second. I've tried coil, plug wires, plugs, and it's not the MAF. Any ideas??

Have someone with a charging system analyzer check the alternator, particularly the diode condition.

Last winter I had some lights flickering in my 02 Golf, but didn't really think much of it. A little while later, I started getting flashing and beeping from the Brake and ABS lights on the dash. After a little searching around on the web, I found that the brake problems might be from a bad ground. I had to remove the battery and the battery box, and underneath all that was the ground associated with the brakes(it's one of a couple grounds there). I cleaned that up, and both the warning lights and the flicker disappeared. I don't know if this was the same problem you're having, but if you don't find any trouble with the alternator it might be a good idea to start checking that your grounds aren't corroded or otherwise dirty.

Checking grounds doesn't sound like an awful idea at all if the alternator turns out to be alright. I can only describe what the lights do as dimming quickly. They don't truly go out, it's just like a weak strobe. Usually it does it when the car is at idle, but once in a while it will even do it at highway speeds. At idle there's nothing I can do, but at highway speeds I can push in the clutch and rev the engine once or twice and that fixes it for a while. It does it on clear nights, or rainy ones. (It seems to do it durring the day too, but as shocking as it sounds it's much less noticable... hmmm)
