This may have been covered before, but twice my F30 330D (2014) engine has started itself after being locked up and left. The first time I was 120 miles away in London when I got an e-mail from the fleet guy to say it was sitting in the train station carpark with lights on and engine running. The second time was yesterday in the car park at work, so far less of a problem. But maybe it's happened before without me knowing.

This is what happens, I think. I park the car and press the stop/start button to turn the engine off. Radio is still playing, but I get out of the car and lock it with the remote - this turns the radio off and locks the car. I go away, with the keys, and assume that's the end of it. But the engine later starts itself - WHY?

Maybe I need to press the stop/start button a second time, turning the radio off , and somehow properly shutting everything down? I don't recall this being explained to me or the manual saying I have to do this.

Anyone else have this happen? Is it a fault with the car, or just user-error?

Never had it(that I know of?!?) but I'm certain mine will only start with the brake pedal depressed. Sounds like a problem.

[Andy30D]

That's a huge problem, must be a coding error, you need to break pressed before it will actually start, it may be something to do with the preset climate control thing where you can have it heat up or air con on 10 mins before you get in and drive to work etc...

Personally, that's a huge security issue, so call your dealer asap x

Could be ASS restarting without you realising. You lock the car with engine already running.

Are 100% sure you pressed the Start/Stop button? I ask as I did this with a 328i I borrowed, filled it with fuel and came back to a running car.

That function doesn't start the engine. You can't have it heat up or cool down; it simply ventilates. Still really useful on a hot day though.

[Slipperyshoe]

+1 on the not pressing start/stop. I've done it three or four times now. Once I stopped, happily walked to meeting, then came back 3 hrs later to a nice and warm running car!

Also as the 6 pot diesel is such a smooth and quiet machine, I may have even walked away with it ticking over! Sounds idiotic but I have a hectic job and a 10 month old so pilot error has to be the reason for me.

^^^ This.
Car was stopped by way of ASS, I got out, when I returned 5 mins later, car was running.
Lesson learnt, always press the car off when you get out

[Kal101]

you either have a fault or not turning it off properly.

Personally I always press the button until all power is cut off. Did read in auto express some time ago about a lady who did the same but in a petrol 4 series

[alpine330D]

As above,for the car to start without the brake held and start/stop pressed would be a serious coding/wiring loom fault.Id either turn the engine off before you leave the car or call your dealer/ghost busters asap :P

[workshybum]

This thread is crazy! Is there not even a warning sound to alert you that you haven't turned he car off properly? Seems like a major safety/security issue if cars can restart themselves once the driver has left the scene.

[Hoppy_70]

Think this may be more common than people think. It does seem to be quite easy to think the car is switched off when it's actually in ready mode. I saw one at the Trafford centre last week, parked and running with the doors locked....

Not done it myself yet and probably won't now I know it's a risk!

[....,,,,..,,..]

I have gotten out of car and forgot to turn off engine, only once and noticed as left lights on lol.

Modern technology is great

Yeah the radio makes sense now why you have to double tap, but then if you single tapped it all turned off wouldn't it make more sense

[WullieD20]

I have to agree with most of the posts above, despite not experiencing an engine restart in my absence. However, I do fail to understand how, with key-less ignition, how I can get out of the car with my keys in my pocket, lock it up and walk away leaving the engine running (for ever more and regardless of key location; ie I could be miles away!!!). How can this be correct, with no indication or warning that the engine is still running.
I haven't managed to do this inadvertently yet, but tried it out deliberately the other day with my son in attendance. We proved that if the car wasn't actually locked, but the engine was still running, someone could get in and drive the car away, just as if the keys were actually IN the ignition, with no trouble (or intervening action by the vehicle). Wouldn't you think that if the keys were 'out of range' the car may even come to a grinding halt???? NOPE!!!
Just another aspect of electronically controlled vehicles that the manufacturers don't seem to have considered adequately enough.

This might not be related to ASS.

On my car (nov 13) if the ASS has stopped the engine and the drivers door is opened the car properly shuts down. Goes into P, rev counter drops from ready to off position and engine switches off.
To move the car again you need to foot on brake and press the button.

Maybe it's something on cars after a particular build date and earlier ones don't shut down. I dunno but I'd be interested to find out.

OP as a temporary measure I suggest you use a disklok.
Any opportunistic toe rag could walk past, smash a window and drive off.

You are correct mate! So it's not ASS restarting the car.

I should think it's most likely that the OP didn't turn the engine off before exiting the car.

Also doesn't help that the stereo stays on when you open the door thus making it harder to hear the engine. Yes I know you can code this out but I really don't dare do it (seriously I am 'El Diablo' to anything electronic).

Swmbo did exactly the same thing.

Engine running lights on after she swears it was locked. Never happened before or since.

I put it down to user error. Told her press to stop then foot off brake then press stop to turn radio off. I thought ASS had kicked in and soon as she got out, it restarted, she didn't hear it and locked the car.

Today I parked the car, the ASS kicked in and I managed to get out of the car without the car restarting ( I'd accidentally put the auto into park) ... But the car realised it, switched ASS and engine off with a warning.

[JB14]

It is ASS and there is a warning on the dash with an audible bong.

If ASS stops engine and you then open the door the message reads something like 'ignition still on' in amber.

If you don't hear it or see it then you can lock car and walk away quite easily.

I have an F10 and this does not happen at all. My wife had started the car whilst I was in the passenger seat, I then got out for some reason and she went to reverse but the car wouldn't engage any gear. It took some working out but I realised it was because the keys were in my pocket and once I'd placed them inside the car it was fine.

This is all wrong. Sorry to be blunt.

If the car is in ASS 'Ready' mode, when you open the door it turns itself to OFF mode (and bongs at you IIRC) and further when you lock the car it kills everything also. The OP said this has happened as they have seen the electrics go off and radio silence.


Sounds more like a specific fault with this one

EDIT - I see others have already made the points above, I probably should've read the entire thread before posting

The point remains though - OP you need to get your car booked in!

[russelldav]

I bet the needle was sat on READY not OFF and as suggested you had not turned the engine off.
