July 10, 201510 yr Hi all! Just coming back on the M6 my check engine light came on, no loss of power, steering / braking / boost / heat all fine! So limped it home, and checked all fluids and the oil was really low! So filled it up, but the check engine light is still on... Could the oil low level have done this? and how do I reset it? Thanks!
July 10, 201510 yr don't think low oil will put the CEL on have you got 'romraider' to have a look at the fault codes?
July 11, 201510 yr Author No, just a VAG odb2 cable, do you know where I can find some scoob compatible free software I can use with it? I'm going to a local garage today to see if they can pickup the code they have an old scanner but not sure if it works, Thanks!

July 11, 201510 yr Author Thanks, I had it checked and this came back:: P0420 cat system efficiently low bank1 This mean anything to anyone? Dgd
July 11, 201510 yr Has it been decatted? Could be oil contamination to the cat, stopping it working properly, causing the cel to flash up. I'd take a wild stab in the dark that the oil consumption is probably down to a worn turbo. But that is just a mad guess Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Author Hi, Thanks for the reply, No its standard exhaust with after market back box, No smoke from turbo at all... Seems to pull well (apart from slow spool but think thats just the way these engines are haha, Its booked in for stainless middle section in a few weeks, Not sure what to do next, can I live without a center cat? will it reduce performance if I got rid of it? and if I did get rid of it how would I de activate the CEL light for the cat?
July 12, 201510 yr The main cat is in the downpipe, you should be fine removing the secondary but it would need to be mapped after. The centre section only contains a resonator, not a cat. The second cat is the short bit after the downpipe. When the car is mapped the cel can be deleted to allow for the decat. Have you got the option to turn off the cel on your diagnostics?

July 12, 201510 yr Author Thanks for the reply! Sounds good but his odb thing was only a basic one and don't think it had option to turn it off, I also just purchased a second hand STI uppipe, is it easy to install ?
July 12, 201510 yr Never done one so not really fit to comment but i hear its not the easiest bit to do, again will need a remap and it will throw a cel up but this can be mapped out too :-) Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Author Always with the CEL lol! My car is completely standard other than back box (plus the uppipe and stainless centre when I manage to fit them) is it worth remapping yet?
July 12, 201510 yr Do everything you want and map it in one hit would be best :-) mine runs fine with no cel with a straight thru centre section, prodrive box, k&n, and prodrive y pipe, however, it'd probably be better mapped lol. Got a 2nd decat pipe to go on then I'll get it on the rollers Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Author Cool, yea that would prob be the best idea, What's the deal with the different Y pipe?
July 12, 201510 yr Apparently it flows better than the plastic one. It also makes getting the intercooler on and off a damn sight easier! Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Not yet... haven't found one cheap enough :-) (I'm too tight to pay too much!) Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Author Haha, me too, the ones I have seen on eBay seem to go for about 120>150! Which I also think is expensive for what little performance will be gained
July 12, 201510 yr From what i can gather its not essential on a mild tune although it is helpful so I'll just keep an eye out til something turns up :-) Sent from my SM-N9005 using Tapatalk
July 12, 201510 yr Keep an eye out on here mate as there's been a couple go for a bargain recently. Sent from my SM-G850F using Tapatalk

July 13, 201510 yr decat will throw up a CEL on yours anyway, the code could well be a blocked cat. Best bet maybe full decat, y pipe,m fuel pump, panel filter then a map.
