these codes keep popping up. i replaced the precat o2 sensor 3 times within 6 mnths. 2 aftermarket bosch & the last an oem from the stealer. is there anytin else that could be wrong? could the octane level in shell 91 be too high that it keeps burning it out? its a 2000 bora 1.8t completely stock with a cai & resonator delete. motor has 240,000 kms & all maintenance is done with oem parts.

Until the vag com gets here go do some tests.
* Check all your grounds. Fix anything that isn't grounded nicely.
* Check your alternator cable. Ensure it is working at low resistance.
* Seafoam test for exhaust leaks (with a rag in the tail pipe). Fix all leaks
* Pressure test your intake to 10 psi. Fix all leaks.
Post back when all that's fixed, what you found, and when you have your vag com. There are some vag com tests that'll tell more.
