My SES light was on last night when I turned the car on (7:25 PM) and today (8:15 AM and 1:30 PM)

However, it turned off tonight (6:20 PM)

I finally had a chance to scan the car

These are the codes that appeared:

My current mods:

JB3 1.4 Beta map 5 on 91 octane daily
RR DPs
Helix FMIC
BMS DCI
RR charge pipe with Dual Diverter Valves
RR Oil Catch Can

I have a 2009 e93 335i with 10905 miles

Had a HPFP failure at around 2700 miles if that means anything

I was wondering if I should clear these codes.... or if it'something that BMW service needs in order to fix the car..

I have not done any WOT since the SES came on last night as I was scared of damaging something.

Any help will be greatly appreaciated

Thanks

It's the cat codes, did u install the catless downpipe o2 sim fix ??

contact terry about the v3, I had the same codes too with the old one and the new one cleared them right up.

I've had the RR DPs since like Octover

and the 02 Sims were install that day

email has been sent to terry...

v3?

Terry said my o2 sim isn't a problem

but a bad 02 sensor..

Didn't you post this thread somewhere else?

Yes.

However, if you noticed in my other thread, i specifically stated that it would belong better in the General section as it is not exactly a 'Turbo' problem

But, I don't know how to delete a thread...
so I had nothing to do this with this one

You'll see my codes are the same, except mine is bank 1 whereas yours is bank 2.

Pretty sure it's a bad O2 sensor.

I actually changed out BOTH pre-cat sensors just to be safe, but if you want to save $180, just change 1 out. Your mechanic should be able to determine which is bank 1 and which is bank 2.

I'll post the how-to in my thread.
