M3 Gone Wrong

[Peter 224]

A few days later....

It happened again!
Car didn't show its correct position this morning. After a couple of hours the bav system and autopilot woke up, then the camera at the front and rear and by 11:30 the side pilar cameras started working, so it was back to normal.

I've filed a service call for Tuesday 19th: my suspicion is a buggy version of the last over the air update, but it is very irritating. I suspect that they will need to roll back and reinstall.

Which version are you on?

Same as me, I've seen no issues. Don't know if that makes thing better or worse!

 

[Peter 224]

More news on Tuesday, I hope!

 

[Peter 224]

Well, they will be replacing the main car computer.... when it arrives. Provisionally booked in for October 25th at Winchester, a 2 day job so a loan car.
I have to say that the service team have been excellent, good communication.

2 days to replace a computer seems like quite a long time...

2 days to replace a computer seems like quite a long time...

Downloading, installing and configuring the firmware, plus all updates ....

 

[ACarneiro]

Downloading, installing and configuring the firmware, plus all updates ....

Even by Windows monstrosity standards, 2 days still seems like a long time!

 

[MrBadger]

Erm. Once they got our replacement car computer (next day) it was all done same day - and by looks of in service messages, half day tops. And that included backup of old MCU and restore into new one.

Absolutely everything was the same including thankfully our lifetime trip and even the keys. If it wasn’t for the invoice we wouldn’t have known it had been replaced.

Would be curious to know your new part number - it should appear on the invoice.

I have *exactly* the same problem. Hasn't happened in a couple of weeks (although I haven't driven much, either). It was booked in at Dartford 2 days ago, but last minute they didn't have any loan cars, so it's now postponed for a couple of weeks.

How did they decide you needed a new computer? Was it once you'd taken it in?

I reported it through the app, for the second time.

Got an appointment and then a phone call from one of the technicians at Winchester. From what he said I think that they will allow the problem to happen once, the second time they replace the computer module. I think they have also looked inside the car, remotely.

Another call today: the modules are on back order.. they hope to have it by 25th, but will confirm: they won't drage me over until they have the part(s) needed.

I was assured that the car will continue to be perfectly driveable, even if it faults again.

What the guy from Dartford told me is he plans to inspect the GPS antenna "which is known to cause other issues" -- and it's not a "wait while we do it" thing, hence the need for the loan car. So it doesn't sound like they're very connected up (i.e. there doesn't appear to be a known cause for this issue, even though it's remarkably consistent).

 

[Peter 224]

If the GPS antenna is feeding duff data to the CPU then it begins to make sense.

I'm not overly concerned, it will be sorted.

Is your car US or China build? I have a pal with a late 2020 US build M3 AWD and he has no problems...

 

[rotor2k]

US

Agree they will definitely sort. I find Tesla Service to be spot on, they have phoned me several times and kept me up to date with what they’re up to behind the scenes.

 

[Peter 224]

I thought it was time for an update...

As of 22 November I'm still waiting for the part to arrive, it is still on order with no scheduled delivery date at Winchester. I talked to the service agent at Tesla Winchester who told me that supply of certain electronic spares is poor, fall out from the general semiconductor shortages in China.

I have a rolling appointment for Wednesdays, reviewed each Monday. Will the car computer arrive before Christmas?
Watch this space!

At the moment the car is mostly working as it should, with occasional states of confusion such as the car thinking the accelerator is being pressed when it isn't and so preventing gear selection and the side camera on the off side returning no image, so de-activating auto pilot.

 

[MrBadger]

Sounds like we were really lucky to get our new ‘car computer’ aka MCU2 supplied and fitted next day.

Is there not a case for declaring that you are not comfortable driving the car and getting a loaner whilst they source the parts? Is your car leased or owned? Any mileage on talking to the lease co?

Not sure I’d be this patient but I suppose with semiconductor supply issues worldwide perhaps we are all going to have to accept things we wouldn’t have previously.

Good luck hope it gets resolved quickly.

 

[GeorgeSymonds]

Parts shortage in China… that old excuse. Point out Tesla are building a million cars a year, they have parts, they just prefer to put them in new car builds.

 

[Peter 224]

I think it may be time to apply some pressure. They have offered to send a ranger out to do a 12V reset... but suggested it would only be a temporary solution and the board needed to be replaced. So I'm not sure there is any point.

They don't have all the parts they need, some US build M3s are being shipped without certain features, like the inductive phone charging pads. Tesla have said they will be fitted when available.
