Anyone have SES after header install? Been driving with the new SLP LT's and RT cats for about a week now. I did the air mod too, and now after 1 week of driving, the SES light came on. Went to Autozone and they're not allowed to check codes anymore, so I'm just wondering what could be the problem. Anyone have this happen? What was your problem? Should I just try and reset it or not drive the car at all until I find out exactly which code it is?

Re: Anyone have SES after header install? I had the same problem-I reset (unplugged the battery for 10 mins) then started it up. It worked fine from then on. I was told to be careful when installing my headers not to touch the 02 sims to anything or else they'll throw lights. Maybe if you hit them on the ground or something it could've damaged them. Call one of the sponsors to the right-SLP tech,tbyrne, someone with that kind of troubleshooting advice. At worst take it to the dealership and get it diagnosed. It should be alright to drive, it might burn more gas though.
hope this helps,

Re: Anyone have SES after header install? Bet you got the bank 1 sensor 2 catalytic low efficency code. That is the driver's side cause the cat was moved further back from the stock location. You will need to delete that code or it will keep coming back.

Re: Anyone have SES after header install? I agree with pedaltothemetal. After my install, I kept getting an ses light, even after it was cleared with autotap. Then we found out it was the rear o2 sensor (I think on the drivers side), so we deleted the driver and passenger o2's and the ses has not come back since. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: Anyone have SES after header install? Okay, tonight I unplugged the battery for a few minutes and then took it for about a ten minute drive and the SES light hasn't reappeared. Hopefully it doesn't come back any time soon. Cross my fingers.

Re: Anyone have SES after header install? Ever since I installed my headers several months ago i've been having problems with the front 02s. Its always about "insuficient switching" or some crap. Doesn't affect performance though, so I ignore it.

Re: Anyone have SES after header install? The SES light came back on today after about 20 minutes of driving. Guess I am going to have to find something to scan it with today. Anyone know of someone in Southern California (Ontario/San Bernardino/Rancho Cucamonga areas) that could perhaps help?? I disconnected the battery only last night and the SES light went off. Do you guys think doing the "Reset the ECM" mod-pulling the fuses, would make it go away? I'm thinking I will definitely need to get it scanned and go from there.

The Emission's operator then found no codes. Then I proceeded to pass the 2 speed dyno roller sniffer test. My engine is also a 427 superstroker! Yeah it's hard to believe but true! I still can't believe it and I have an A4!
