general problems of the 2001 Volkswagen Jetta

My abs light has been on and I don't know how to get it to turn off. My traction control light has been on and don't know how to get it off. I have bought a new coil pack and spark plugs and spark plug wires and now my check engine has came back on. Please help me with this car. Thanks. God bless u.

The 2001 vw Jetta has had three O2 (oxygen) sensor failures since purchase in September 2000. In addition have experienced the need, according to dealership, to have O2 sensor cleaned, which again caused engine light to appear. Have talked to vw of America, claim my Jetta is not one of the cars issued as a recall for the O2 issued on 1/11/2002. Yet it is a continual problem. Have spoken to two vw mechanics. They claim vw is aware their supplier of the part has manufactured faulty O2 sensors, yet continue to purchase these parts. Talked to an independent mechanic on an O2 needing a 'cleaning'. Independent mechanic stated this should not be necessary for any vehicle. Makes me wonder if this is to avoid the lemon law -- list the repair as a cleaning instead of replacement. Vw of America has issued me a case number, yet vw feels this is a dealer problem not a corporate problem. I strongly disagree, based on having an O2 sensor fail from two vw dealerships. The dealerships can only supply the parts from the manufacturer inwhich vw has authorized. Confidence in vw's recall jarred. Experience with their cosumer service and satisfaction dismal. My Jetta is experiencing some situations as the recalled cars, yet I am not covered under the recall umbrella. How do I best protect my safety, as well as my investment, my car, when it comes to vw practices? dt.
