I fitted my dp fix today and cleared the codes with my bt cable. drove the car for 5 miles and the light came on again, checked the codes again ans they said back lamba sensors after CAT.??????? do i need to adjust the dpfix??

[vasillalov]

Are you sure your sensors are not damaged?

[mikey335iT]

yeh the sensors are fine as far i know. its only been since i fitted the dps. sensors had to be relocated slightly higher as the dp i baught were for LHD and mine is a RHD as i live in england.

[mikey335iT]

what fault codes come up wen the dp's are fitted as i asumed the lambda sensors would be the ones, i was thinking of adjusting my bms dp fix to 3oclock or 9oclock does anyone know if this will work. any help would be great as im not sure if the problem is that.

Which o2 sims are you using and what code did you get exactly?

codes..
2F6C exhaust fume flap
2CA9 Lambda probe heating behind cat 2
2CA8 Lambda probe heating behind cat 1

I Have just cleared codes again and reset lambda on the command section of the BT software.
I have the adjustable BMS DP fix so not sure which setting to put it on

Any advice would be appreciated.

Those are not DPFIX codes. Maybe you just connected it wrong? Email me some photos if you want me to double check.

hi there typical as it has been raining all day today so i cant get to the ecu to take pics until tomorro, but when wiring up the DP fix i was left with a black male wire and it didnt say wat to do with it so i just taped it up?????? i am not using a JB3 my 335i has been re-mapped so its being wired straight to the ecu. any help would be great as this light is doing my head in, i keep clearing the code then after maybe 5-10 miles it comes back???

[mkPOTO]

are you running stock exhaust with the flap vent unplugged? that is what the first one is

[mikey335iT]

yeh im running the stock exhaust with it disconected in the boot, but would that cause the other 2 codes??? i assumed that as im running with no CATS i may aswel disconect it, i was told the fume flap was there to warm up the CATS quicker??

[mkiv]

are you missfiring?

[mikey335iT]

yeh it was miss fireing the otherday but since i changed the HPFP and installed the dp fix it has been running ok. just a light on the dash. confused???

I donno if iam throwing that lambda code but iam throwing some kind of CAT code. Iam sure its because of the DP fix. I installed my downpipes and then my 02 sim and the car ran without a SES light for a week, then it popped up and i cleared it,2 days later it popped up again and i never even bothered trying after that. However i could have the SES due to misfires also.

[mikey335iT]

Hi jon I've realized I fitted the dp fix wrong as I was left with one cable left which I assumed was for the JB. I will be fitting it properly on my lunch break so I'll take pics an update later, I left the light on and didn't clear the code last night an it started fine this mornin so the miss fire has gone after replacing the HPFP, I was told it was mis firing In the mornin because the pump had no presure.

[mikey335iT]

so i think ive sorted out my problem i hadnt conected one of the male black cables to #19 yellow cable so that was probably the cause, so far ive had no SES light come back and i have a clear dash board for once. lol. im hoping my problems fixed and the car is running so much better now, No Smoke pouring out the exhaust, power feels better and its idling better, just shows wat can happen if you dont double check things. thanks for the help everyone

You mentioned "No smoke pouring out the exhaust", did you have white smoke coming out especially when you would come to a stop? I'm trying to figure out my issue I had, simple fix was to re-install the cats to the exhaust. Cleared the codes, and after a few days the SES came on tonight. I couldn't take the smoke pouring out so, hence; the cats going back in. I installed a PROcede but that didn't help either to solve the "pouring smoke" issue.

Thanks,
