Another possible solution I've seen floated about is to replace a Valeo regulator with a Bosch brand. This car was made in Mexico. I heard that, if made in Germany, the myriad of problems reported on VW's is avoided. I don't know which alternator brand I have but I did find a Bosch brand for this model listed in Autopartswarehouse.com. Also wondering if the sound system is too hot for the Jetta's and Beetles (subwoofer in Monsoon sound system). Another idea is to get an after market voltage stabilizer and grounding kit, I.e. http://www.andysautosport.com/volkswagen/1999_2004_jetta/performance/ignition/ground_kits/nrg/nrgi00000297.html since it seems no one has found a conclusive solution to the electrical issue(s). Everything has been replaced - for many, many owners as I have read on numerous forums - even a class action suit in the making. If I can stabilize and even out the AMP draw this may be the catch all for what seems to be intermittent electrical demons all around......thoughts? If that doesn't solve it then back to the first solution I mentioned - but it seems someone would have identified that solution by now. I've seen, 1, 2, 3 and more fuse boxes replaced and no final solution with that.
If I replace the alternator with the Bosch and it does not stop the smell, do you think the voltage stabilizer and grounding kit is a reasonable catch all attempt to even out these issues?
