Does anyone living in the vicinity of I-90 and Beverly Road in the NW suburbs of Chicago have a Ross Tech Scanner and would check my codes for a reason why my CEL is coming on?
I have an ECS VAG Check Pro but I haven't been able to figure out what these codes refer to:
0421 Warm up catalyst bank 1: Efficiency below threshhold and
1177 Bank 2 Lambda correction downstream of catalyst: Contol limit attained
It was suggested a Ross Tech Scanner would be able to positively i.d. these codes.
