Codes 132 & 152, UPDATE: NEW CODES 300,302,303

[SMOKE EM IF U GOT EM!!]

Little history. Cars fully broken in w 3900 miles. Jb4 has been in for 1500 miles. Cars been running great lately w the cold weather. Parked it at work this am, got back in it afterwards and started it up and the check engine lit up. I have the p3 gauge so the codes 132 & 152 bank 1 & 2 sensors high voltage came right up.

Any ideas? Could it be the tune? Just a coincidence? Didn't install stage two so can't clear the codes. Asides from pulling the tune out and taking it in anyone have any suggestions? I find it weird that codes for both sensors came up together.

If you've never touched the downpipes & o2 sensors you could take it in. Or delete them with the P3 to see if they come back.

Didn't know you could delete with p3. Cool

Nope. Haven't touched either. You think I should pull the tune before going in w it or just leave it alone and hope for the best? I cleared them earlier and will let it sit overnight. If they come back on I'll make the appointment. I did wash under the engine for the first time the other day since installing the jb4. Possibility something got wet and maybe a gremlin working its way out. Possibly in need of just a software update. Idk

I just finished telling someone how much I was enjoying the car and it's been trouble free for a first run car. Haha. So much for that.

[SMOKE EM IF U GOT EM!!]

Codes back on this am. P3 gauge wont clear em either. Says they're cleared but c.e lit still illuminated. Guess its gotta go in.

Hope all goes well for you, this may be the first warranty indicator of a piggyback on a car?

+1, please keep us posted

Thanks guys. I'm hoping it has nothing to do w the tune. Hoping its mere coincidence. Gonna pull it tomorrow and drive it till after the holidays and see what happens.

Post a link to another m4 with a warranty issue?

[SMOKE EM IF U GOT EM!!]

Ran jb4 in my n55 f10 for almost 20000 miles w zero tune related issues. Highly doubt it's tune related. More like BMW software issue related than anything. But you never know. It was a beta tune when I purchased it, new(ish) motor and dme as well. Also haven't updated firmware yet since I've purchased it or installed it. So I'm just gonna play it by ear and see how it pans out.

[SMOKE EM IF U GOT EM!!]

Update:
Pulled the tune and cleared the codes. They stayed off for as long as it took me to get down the driveway and came back on again. So it's definitely got nothing to do w it IMO. Appointment set to bring it in tomorrow. Hopefully it's a simple software issue. Can't see the sensors being bad this early. It's stating high voltage in positive connection to battery in the probes pre cats when I scan it.

[SMOKE EM IF U GOT EM!!]

Update

Came down to bad sensors. They changed both pre-cats and all is good now. Guess it must've been a faulty batch or something. Either way all is good now. Dealer said they also found a broken hose clamp on the intake tube. Idk if they did it as a precaution as I read in another thread someone had this done as a recall issue or if it really was broken. When I pulled the tune out I double checked everything and didn't see anything broken or loose. She's back to normal now. Gas mileage was terrible during this. Got about 130 miles to the tank.

It is quite possible that the broken hose clamp was the primary problem. If this was causing a small leak this could have been throwing out the metered air calculations and confusing the ecu. As a result the car could have been running extremely rich. Over time this could foul the pre cat O2 sensors and cause them to fail. This also would explain the poor fuel economy.

Very possible but if it was broken it clearly wasn't visible. Didn't have any drivability issues even while check engine light was on either. Glad its fixed regardless

Well...Light back on. Constant drive train malfunction and massive misfiring and trembling can be felt in the car. Codes are now 300,302 &303. Different codes from before but same frustration level. Missed a big rally run today cause car was immobile. This is making me lose faith in this car and takes the whole fun out of ownership of it. Didn't even get through one full tank of gas since dealer worked on it from the last issue.

Third will be the charm. Hopefully this is it w this car and the bugs. If it goes in for the same thing again I will definitely entertain this idea.

Risks you take running a jb4/piggy back tune...

I don't consider it a risk of running the tune, more so the new car bugs and gremlins coming out. Early build date doesn't help me either.

You really don't think this is tune related?

No
