Sorry if this is posted someplace already. I've looked all over and can't find anything helpful.

I've got a 2003 A4 1.8T Quattro. I can't seem to keep headlights or tail lights in it for more than about three months at a crack. I've also gotten really good at changing out ignition coil packs because I get one going out about every two months. I also have had all the oxygen sensors changed along with the cat but the engine light keeps coming on. The codes are telling me that there is a problem with the brand new O2 sensors.

I'm getting really tired of all of this nickle and dime BS. Does anybody have any ideas? Maybe the voltage regulator spiking? Bad ground someplace in that mess under the hood? Any help would be appreciated. Thanks
