"Major emission control components," which include the cat, ECU, and OBD, are covered for 8 years or 80k miles by federal law. This applies to MY95 and newer cars and is not affected by changes to VW's or other mfr's warranties. Cali vehicles may have additional coverage. See http://www.epa.gov/otaq/consumer/warr95fs.txt. Good luck.Altair 4 said:can someone familiar with the emissions warranty please clarify the parameters (time, mileage) for cat converter coverage for 49 states and California? Did it change between the "old" warranty and the "new" warranty? Doubtless someone will find this useful. TIA.
Ouch, no doubt I'm replacing all coils before anything bad happens.bretb said:I think its ~ $1200
Having all the coils replaced doesn't seem to assure you that the cat is going to be Ok. We know by references that the "J" coils may be misfiring or failing too.bretb said:At 6k, I had a flashing CEL. Pulled over right away, had it towed, and had all four coilpacks replaced. At 10k, I had a solid CEL. Drove to the dealer, vag-com said cat error. Drove it for a week until my previously-scheduled 10k appt. They couldn't find anything wrong with the cat, but the #4 coil was periodically misfiring, so they replaced it. Drove it for a month, to 11k, when the solid CEL came on again. Vag-com again said cat error. Drove it for a week, then had the cat replaced.
A defective cat can't damage coils, but defective coils can damage cats.Can anyone say if a defective cat can burn or blow coil packs? Kept changing and kept misfiring when engine heats eventually blowing a pack or even two.
