Check Engine & Airbag lights both have been on quite awhile (15K miles) although it hasn't seemed to effect performance or MPGs. Took it for bi-annual smog check and although it PASSED the "emission" test it FAILED the "visual" insp due to "Check Engine" indicator light being on. Took to VW Tech who wasn't able to access/read codes from OBDII monitor because of "Link" error and "Proprietary Information" issue???
Wondering if anyone else has ever experienced this?
Ultimately, was told I'd have to take it to dealer to get diagnosis/repair. Read previous posts relating to check engine light issues and should mention I DO NOT have an aftermarket stereo or electrical components of any kind installed. Car is the same as when it was delivered new to dealership.
Prior to the above events, I had its very first diagnostic eval done on 'check engine' light soon after I first noticed it (during a regular servicing). At THAT time, the Tech was able to obtain OBDII codes, however was reading more than one code, so he reset the light and wanted me to drive it until the 'check engine' light reappeared. Said he could re-check for codes then, and would likely narrow it down to just one. Sure enough, not too long after, the light reappeared and at the time I wasn't able to get it back over to the Tech to re-check. I'm not sure what could have happened between the first check and the second, but I'm hoping someone out there can suggest what I should do next? Take it to dealer? Not looking forward to spending that kind of money during the holidays. Still, I have to get it to pass smog for DMV registration by the end of the month. :( Please help!
I feel like I'm running in circles... it's terribly exhausting. :/
