Hey guys,
So I have a few codes poping up on me and even tho i have some idea what it is,I would still love me some help.
Car is 08 e92 with 65k miles
First issue is engine light.According to my research it probably is 02 sensor.Carly threw this code : 274A failure detection cyl.2
When i clear it,it stays away for a week or two and then it comes back on again randomly.No limp mode.
http://www.m3post.com/forums/showthread.php?t=859209 this thread describes similiar issue but there is no update on it.
When i took it to a shop (they have some advanced diagnostic tool) they also found these codes:
27B1
274A
2b43
2b44
2b45
2b46
2b47
2b48
2b49
2b4E
all refer to Misfire impairing exhaust emission at several cylinders pretty much besides the 27B1 & 274A.
They didn't really know what it is,they just told me to take it to a stealership which i wanna avoid since i had bad experience there.
Second issue is pretty much these 2 threads:

I get 5Df0 pump motor faulty and 5DF1 pump motor connector damaged codes. These are yellow ABS/DSC/Brake lights.They pop up randomly and also clears randomly after some driving or turning off/on the engine and driving couple miles. It started very mildly where i would get them every month or so but recently they started poping up like every other ride so it got worse over time.This is probably a failed ABS unit.
They checked it and did some work on it in the shop (I did not rly understand the mechanic but he said they cleaned some stuff and played around with it,aligned it or something).
So if this won't help and the codes come up on me again what should I do ? Do i just send the ABS unit for a repair ? Like a lot of guys facing this problem did ? (cost is around 250 for repair vs new unit around 3k afaik).
Any help will be greatly appreciated,sorry for the long read.
I'm not too keen on ABS systems or anything of that matter. Too much electronic BS... BUT, I can try to help with the engine misfires.
When is the last time spark plugs were replaced? Misfire could be either injector issue or spark issue.

Trying to reset engine light, through instrument gauges and BC button. The only thing that cames up is an Explanation mark between cluster on panel. Nothing gives me a reset.

Loki thanks for coming in. Spark plugs has been changed 15 000 km back so i thought it can't be that, but it has been over 2.5 years back so not sure....
No problem!!
Hmm, likely not that then. lol You said it may be o2 Sensors. Have you replaced those? As far as replaceable parts, that's quite a cheap one compared to other things for these cars. I would start there since you think it's that. And see if the codes will reset. It would be easier to troubleshoot once those are proven out of question as well.

Yes i am gonna get the sensor in question replaced and go from there, I posted in hopes that someone had this issue before and could direct me the right way before me potentially spending on stuff that might not necessarily fix the issue you know
I hear ya man, money isn't easy to come by these days. lol I would start with o2 sensors personally, and see if codes clear. If you're still getting individual cylinder misfires, then we can address that. Keep us in the loop!
