Multiple Code Hell (2015 320i F30) Help!

PuterPro · 10-20-2020, 08:23 AM

Hi All! Sorry it's long, but I wanted to give the details and there's a lot of them!

HALP! My friend Rudy (long story) is sick. It started simple but now I'm in code hell.
Due to COVID sheltering (high risk) my poor 320i was just sitting. I drove it every 2 weeks or so, but since it's 5 yrs old I knew the battery couldn't handle not being charged, so I did some research and got a CTEK MSX 5.0 and a Topdon BT100 checker.

I didn't realize you're not supposed to charge direct to the battery, so I did the 1st time. The checker indicated the battery only had 17% health, so I did a Regeneration charge from the FRONT terminals. Didn't help. Then the fun started.

My 1st issue was a Chassis stabilization error (DSC). (I had a code reader but it was very old). Then suddenly a friend of the error showed up, his cousin ABS error.

At this point I did some research and found it might be the low battery, so I bought a Veep Bluetooth adapter and Bimmer tool lite app. I cleared the codes and all was well for two days, so I replaced the battery. I used this from AutoZone:

Duralast Platinum Battery H8-AGM Group Size 49 900 CCA

I bought the full Bimmer Tool app and coded in the new battery and re-cleared the codes.

No joy. Back they came. But they brought some friends.

Now Cruise Control fault, and Restraint failure warning joined the party, and the ABS warning brought a new symptom, Electric Steering failure. Works fine until the ABS error hits, then I lose it. No separate fault, but when ABS fault pops up, steering goes heavy.

The app didn't seem to give much detail, so I gave in and got a Foxwell 510 Elite on Prime Day.

Here's the codes I now am fighting:
1B0A21 Rough Road detection: no wheel speed signal received.
1B0A65 Driving speed wheel sensor fron/left signal change Not plausible.
1B0A67 Ditto Front/right
CD944D Signal (actual wheel speed 46.0.1) invalid, transmitter DSC

Now, I suspect the speed sensor(s) could indeed be bad since I live in Florida and it's been raining like mad with the car mostly parked. Rust ...

BUT.
That doesn't account for the others:
480686 Wheel speed sensor: Drive-off recognition, right rear right.
480840 Wheel speed sensor: Voltage supply short circuit to ground, rear left
480875 SAME rear right
480AAA same, sporadic fault rear left
480AB3 Wheel speed sensor Plausibility, signal spike, rear right
480AB4 Wheel speed sensor Plausibility, signal fault, rear right

OK, we've got an electrical issue, but WHAT? It can't make up it's mind as to where.

{In his best TV Voice:} But WAIT, there's MORE!

CD0487 ZGM: Synchronization process for FlexRay failed. REALLY?? Ray needs to stop Flexing in my car. (I have to rely on humor or I'll cry at this point.)

D514BE and D514SE Signal (vehicle speed, 55.3.4) invalid transmitter ICM

Then it gets absurd.
030101 Power Window, rear door on driver's side relay for closing, no output voltage.

Finally:
D916C3 No message (status emergency call 0x2C3) receiver FEM, transmitter TCB

I would believe a wheel speed sensor, perhaps shorting cable? But I don't get the rest of the codes. Is there something common to all those systems?

I did check the front fuse box (engine compartment) for water leaks, ditto rear luggage area box, which I'll pull and check the relays and connections for corrosion / water. I DID have some small leakage into the trunk from heavy rains and the drains clogging (cleared and dried, not a lot ...)

I cleared the codes but DSC and ABS popped right back up, as did Restraint.

Could this be a JBE problem??

ANY help or thoughts, PLEASE weigh in, thanks so much in advance!

What's common to most, if not all, of those issues is that they require input from all four wheel speed sensors. You need to use an OBD diagnosis tool like the Foxwell NT510 to test the function of all four sensors. It does so while driving the car to see if the sensors are sending the speed data. You can do it in a driveway, as the car only needs to be going 2 to 3 MPH over a short distance.

I have a 510 Elite. I'll try the live data. I knew it did that but don't know where it is in there, I'm a computer guy so I should find it, I'll ask if I don't, I'm not too proud to say IDK ... (you NEVER stop learning! LOL).

What about the other errors? I get that Cruise, ABS, DSC are all related to wheel sensor data, but why Restraint??

Thx so much for taking the time to read my novel!

EDIT: Found it. Both Wheel RPM and signal quality look fine for front wheels, BOTH rear sensors show Zero. Figures since it was throwing codes for both.

Bad ground? Shorted wire on one of them? Sadly I live in a "gated community" that has a bunch of grumpy old folks who will get all up in arms if I pull a wheel to look. {Sigh} We all make bad decisions in life, this community is one of mine. LOL

I can pull off working in the trunk or cabin and know my way around DVM's and the like, so if you know a connection point I could access in the cabin or trunk ... (looking innocent).

Thanks, that's a great idea, but the only ones relatively near me are in Pompano Florida, about 45 - 50 minutes south of me. I used to use the one on my Navy base in San Diego years ago, they charged about $6 per hour LOL.

MANY years ago ... Thx for the try!

BWbimmer · 10-20-2020, 06:43 PM

Not sure if a torch and a curb at a quiet place would be enough for you to get under the car to be able so see the sensor. It's clear you will not be able to access the connectors in the wheel arch

Wires · 10-20-2020, 08:16 PM

Stupid question, but have you driven it a bit since you swapped the battery (and the battery is fully charged)?

I had pulled the battery terminal, and during the first 5-10 minutes of my commute, it lit up tons of warnings twice.

Quickest check would be to disconnect the battery, leave it for 5 minutes, reconnect and do a 5 minute drive.

Yep. Both ran it and also, while I had the neg disconnected for troubleshooting, I did a full charge with my CTEK 5.0.

Checked it with my Battery Tester and both health and charge were 100%.

Thanks much for the thoughts, ya never know when a simple question causes an Ah-HA moment!

Wires · 10-21-2020, 12:54 PM

Sorry... no help then.

I didn't expect the Christmas tree of warnings when I pulled the battery terminal off, so figured you might have an easy fix.

usher221 · 02-28-2021, 10:01 PM

PuterPro Have you been able to fix your issue and if so what fixed it? I am in the EXACT same situation...

I have cleared them with Bimmerlink drove the car for ~ an hour but still 9 errors left.
I have not disconnected the battery yet....

I did register the new battery with BimmerLink. Is there something else you are referring to? I also have the BimmerCode app. The battery I bought is same specs as the original one.

Yes, this is what I was refering to.

The codes still sound like batterie problems

Did either of you get this resolved? I’m having the same issue after a battery replacement and successful registration using BimmerLink. HELP!!!

You have to clear all the codes after the battery change and then start from scratch

so this is not a wheel speed sensor issue?? I started getting the abs lights and previously my F20 was the same and I changed that 1 sensor and everything is fine.

now my F30 has multiple codes. similar to this thread but I just assumed it was the abs sensors? I haven't change it yet though.

Billfitz · 03-02-2024, 07:57 AM

A faulty ABS sensor will trigger codes for any and all processes that utilize wheel speed data. The first step is to verify if a sensor is the problem using a tool like the Foxwell NT-510, which gives a real time readout of sensor data.
