    My check engine light has been on for the last 3 years. I have taken it back several times to the dealership. The light goes off for several days then returns. Also I my air bag light is on. The dealership claimed it was the seat belt. They replaced that, got home the light came on again. I replaced the ignition coil for a cost of $800+ and again my bug is having all the same above problems Its a lemon!!!!!

    My check engine light comes back on within a day and usually on my way home from the mechanic. Farthest I've gone [after "fixing" the problem] was 73 miles. Last repair the check engine light came back on after only 23 miles. No codes, no emission problems - just a quirky car! The light first appeared around 40K miles and went on and off for the next 20K. I'm up to 114K miles and it's on all the time now.... I know there is nothing wrong with the car. My mechanic knows there is nothing wrong with the car. Now all we have to do is convince the Ohio E-Check savants........LOL

    Mine continues to throw a code, reading about it on the internet seems to show that this a software problem that changing sensors does NOT fix. I've been driving mine now over 40,000 miles with code 2151 ( I believe) throwing every few days...

    Chk engine light comes on for no apparent reason. Had thermostat replaced, ABS sensors replaced, MAF replaced, it seems EVERYTHING is tied into the Check Engine Light. Runs ok when I'm not looking at that light, but every time I turn around that damn light comes back on. This is THE worst car I have ever had. Will not buy another. Problems appeared around 82K and have not quit since. Have spent close to $3,000 on just little issues with this piece of crap. Will fix one thing only to have it affect something else. And I always thought the Germans were suppose to know how to build a car. Maybe Mexican labor didn't follow the build instructions, but whatever it is it has me EXTREMELY frustrated!
