1yo with 20k km. Suddenly, stopped working. It only ignites the dashboard that mentions tons of errors like drivetrain malfunction, etc. it even says that wiper blades stopped to work. Cannot even move the seat.


The car is in the neutral and I can remove it from the parking brake.

According to all the messages pulled from the obd, it looks like the CCU unit issue.

Is there a way to reset the car and make it movable to drive to a dealer? Or is towing the only option?

[AiredaleDad]

You can try rebooting IDrive by holding down the volume roller for 70 seconds. Or get a Bimmer Ulility dongle. If you plug it in to the OBD port you can read the codes, and delete them inf you need to.

Tons of errors accross disparate systems on most cars is sign of 12V system problem, either discharged or bad battery, loose or damaged battery cables. If you have a voltmeter, you can check the voltage across the terminals. Normal/healthy is actually above 12V, more like 12.7 Volts.

[finn123]

It was 12.4V when I checked. Nevertheless, towed the car to the dealer. Let’s see… I also had errors about impossibility of charging, etc. it feels that it’s the CCU.

[Blue Sky]

12.4 is low, maybe in the brown out region. Let us know what it turns out to be.

I got my car back last week. They’ve changed 12v battery and it started to work. They said there were no obvious errors, but it happened again today after one week of usage of the car. Coincidentally, the weather today is cold and it’s below 0 C as the last time it died. Called bmw roadside assistance, they sent a road assistance, they tried to jump start, but the voltage was obviously ok. Then decided to disconnect the 12v battery for a couple of minutes and connect it back. The car got alive again. Strange. Any thoughts? Going to drive the car to the dealer tomorrow and see what they suggest.

Btw, there are 200+ errors.

There are a couple of them of concern to me

21F325: High-voltage battery unit, KL30C voltage sensor: KL30C triggered
801211: eKMV: Shutdown due to fault in the high-voltage storage tank refrigerant shut-
off valve

[finn123]

And after a couple of hours of parking it’s dead again.

Check for this. Could be partially damaged wiring... Had this happen to one of my ICE cars last month. Every warning light went on, bizarre driving behaviour.

Turns out a critical wiring harness had been chewed through by squirrels.

Had that happen before in a Land Rover LR3 I Owned.

Since the first time the car died (19th of Nov), the car spent most of the time in service. I got it back 2 times - 1st time they changed the 12v battery, the second time, they updated software and did various tests. Yesterday, got my car back and today it’s dead again (3rd time). Still the same error, still the same symptoms - it just randomly dies and has to be towed.

My bet is that CCU is to blame… let’s see. It’s so annoying. I’ve driven rental cars more than mine since I got this cpo car…

Leave the car with them and have a foreman drive it home for actual quality control. Seems obvious it’s not lasting long after the initial repair. It would be easy to just verify after a day or two of being parked if it’s going to kill the 12v battery again.

The car is still at the dealer and they don’t have any updates except that they were told to remove the battery and do measurements of cells and other components. The dealer is freaking slow and hasn’t done their job yet. Awesome job, BMW. That’s how you treat your customers. Buy a car and keep it in service.

That’s how they treat “those customers”, just don’t be one of those and start playing the game they don’t want you to play….

Call NA, Customer Relations, start polite and end with compensation. That game goes deep.

[finn123]

We don’t have this in Finland. All this service is sh*t. Here BMW is just an importer. They don’t do anything. After sales is just a joke

[Igor_M5]

You’re saying there’s no way to bring up your case to a department that will provide compensation for the troubles caused by their defective product? Is there no such thing as consumer relations offered to EU owners?

What I was suggesting is simply a tactic approach before being left with no option but to escalate to levels were consumers have legal ground.

[finn123]

Well. I got my car on 17th of Jan (it was staying at a dealer from 13th of dec). The said they disassembled the high voltage battery and changed the sme there. Today after 2 weeks of usage, the car is dead again. That’s the fourth time. Sigh

Can you lemon this car? I would talk to BMW Corporate if you haven’t already to see if they’ll take this back and refund you or give you a similar car. That, or hire a lawyer. Sounds like it qualifies under the lemon law, but I’m not a lawyer, and not sure this is a thing in Finland anyways, so…

Good luck in any case, that really sucks!

I’m trying to negotiate that with the dealer who sold the car to me.

Frankly, I got the document from the past service actions.

BMW factory suggested the service to remove the high-voltage battery, check the wires, if wires are not ok, change them, if they are OK, change the SME.

There is a zero word of actual troubleshooting of the SME module. What a shame. 3 attempts were just guesses without real understanding of where the problem is. Now it’s 4th…

Yeah, it's unfortunate. No matter how good a car model is, once in awhile you end up with some lemons. Especially int he first MY of production. And the G60 is a completely 100% different car from the G30.

I learned a while back to never buy the first MY of a new edition. The first year ends up Buggy, and the second year usually ends up with most, if not all of these bugs being corrected (IBS, Steering spindle, etc.) and being one of, if not, the best MY, with the most features for the lowest price. After that they either take away what were standard features, and make them paid options, or they go away altogether if they did not sell much. There are a few things that change just to differentiate the model year. I heard that Oxide grey is going away soon as a color option. (Glad I got mine).

I have different experience. Back in the end of 2020, I ordered an X5, which was delivered in December. So it was a MY2021. The model has been on the market since 2019. Still, I covered 30k on that car and sold it in the end of 2022. I had numerous problems - 25 visits in total. The car has numerous problems starting with metal dust in the gearbox that was replaced ending with jerks, which they couldn’t fix, loosen seat frame, and etc etc etc


On contrary, after x5 I got a used Taycan MY21. It was a 2 year old car with 30k km on the odometer. What a lovely car. No issues at all. Decided to make a change as it was approaching 100k mileage and traded that in for this i5, which turned out to be a nightmare

Ah, I see. I had a previous 2005 and Rover LR3 (Discovery 3 in Europe) It was a first model year and had all kinds of issues. I traded it in in 2013 for a Range Rover Sport. No issues. I also had a 2009 Volkswagen CC (Passaat CC in Europe) 2nd model year Luxe edition. I had no problems at all and would likely have kept it, but when I transferred to Spain, the Government would only ship one car. So we shipped the Range Rover and sold the VW. I had purchased a Mercedes CLC 200 and drove it for 5 years with no problems, and bought my current 2025 540iX which has so far not had any problems.

I still am at only just a bit over 600km. But from what you have said your problems started almost from the beginning. It may be more of the difference between ICE and EV, because In my opinion, BMW is early in going all out in the EV market (No offense intended to those who love their BMW EV's). They have been building ICE vehicles forever and the B58 I6 is a well established and proven engine platform.

[Blue Sky]

Sadly the Taycan can often turn out to be problematic like this too. Glad you had a good one. Hoping i5 will be more reliable. We’ll see.
