Title: 2nd 02 sensor reading - BAM engine , 8N0 906 081 BQ Post by: 20VTMK1 on November 06, 2013, 10:59:02 AM Hi All ,
I am getting a reading of 20deg C on the 2nd 02 sensor (Cat temp) , as a result the readiness bit for the cat temp is sitting at 0. I am inclined to believe that this is messing about with the trims , 630 deka's (2.3 % idle , 0.8 % PT) I have read the posts on the 2nd 02 control and I do sort of concur with the symptoms . No error codes , just a low reading that doesn't change .. Any comments or experience . Thanks Title: Re: 2nd 02 sensor reading - BAM engine , 8N0 906 081 BQ Post by: 20VTMK1 on November 11, 2013, 12:14:30 PM Hi ,
Just to report back . I changed the 02 sensor .. Trims on idle dropped right away. Doubt its a co-incidence . Also , car is more spirited on part throttle now . |
