check engine light/ exhaust problem question
#46
The primary 02's are for the dme to read what the motor is doing and adjust trims. Delaying those messages can be harmful.

hello again,
i had the o2 extensions put on the rear sensors and i had the ECU flashed with EVOMs. literally as soon as i pulled out of the shop, the CEL came back on! it was late last night when i picked the car up so i didnt bother going right back but i will email them today and probably bring it back tomorrow. Any thoughts on this? do you think they will need to keep adjusting the flash? or do you think the CEL wasnt fixed at all and i should start looking into some new cats. and if so, anyone know where i can buy just the cats to the older fabspeed 996 exhaust system?
thank you!

Also- i just want to point out that the EVOMs flash was noticeable to me right away.. and this is coming from someone with no experience with "tuned" cars... i could really feel the added power on my drive home

thats a good point though, the shop should scan it before doing anything huh...

No i havent scanned it, i dont have a scanner.. lol. i bought the greddy infometer touch and it wouldnt clear the codes so i sent it back :P. can you recommend any that you know will clear them on the 996tt?

Any OBDII scanner will do the trick.

Just in case you forgot reading this.

Durametric. And you could have gotten that for free if you did a Softronic or switzer tune.

update: i got gas today and when i started the car back up, the CEL was gone... problem solved!... at least for now. Ive gotten multiple CELs on Mercedes from the gas cap not being on properly... i guess the O2 sensor extensions and ECU flash did the trick. thanks to everyone for the advice.
The EVOMs is awesome, i would definitely recommend it to those looking for performance upgrades im very happy with it.
im hoping the light stays off this time, but if it comes back.. new cats? lol

No, if the CEL comes back you scan the codes with the Durametric you bought, post them up here.
You DID buy one, right?

problem finally solved
problem finally solved.
i waited a bit to post this as i wanted to be sure it wasnt just another temporary solution.
i needed a new MAF sensor.
thanks again for all the help!

Markski's exhaust is a work of art and sounds amazing! Just do a search and you will find plenty on this forum.
