No power out of the blue!

Driving my family this afternoon I got warning message to the effect of Emergency Brake Failure. About two hundred yards on I got some kind of engine warning (I was panicking) and the car stalled. When I tried to start the car, I got a gearbox error followed by a DSC error - the car wouldn't start.

There I was in the middle of a busy road with no power and whenever I pushed the starter, the car made a weird electronic beeping noise and wouldn't turn over. I also noticed the usual warning lights didn't come on, only the handbrake and airbag lights. I tried to get the card into N resulting in the gear indicator flashing between N and P. So I switched on the hazard lights and got out. Waiting for the recovery truck I noticed the hazard lights were a little dim. When I tried to get back into the car the central locking didn't work.

So I couldn't release the parking brake (I wasn't keen on using the boot release) or get the car into Neutral. When the recovery guy came 40 minutes later the hazard lights had completely faded and the hazard switch was flickering. When we got the car home I noticed one reverse light and one rear fog light were on but turned off after a further one hour - presumably when the battery totally died.

I plan to try jump start the car tomorrow morning before taking it to BMW on Monday. It sounds like there was a sudden loss of power and who knows what else. Any ideas?

From what I've read, initially this sounds like a battery and alternator failure. Although, it could be anything. The dealer is going to rape you, don't know of any independent shops that specializes in European cars?

I hear you about the dealer. There are a lot if so-called specialists but in reality those I've met when I had a Mercedes had very little speacialist knowledge and I ended up using forums to tell the mexh what to do I did eventually find someone who knew what he was doing which helped me to sell the Merc. With me being new to the BMW world the search begins, again...

Thanks. When I jump started the car this morning it started and ran as if nothing had happened. The symptoms seem to indicate a major short (it was raining lightly yesterday) and the battery went flat. It seems odd that the car would die, whilst driving, of a flat battery. So you're probably right about the alternator too.

I'm seeing a mech tomorrow about the gearbox. I had the pan and tube replaced and the gear changes aren't great. I raised this in an earlier post and it was suggested that I have the gearbox reset using DIS, to account for the changes in oil level and wear. Either way, I want the mech to check the oil level and hopefully he has DIS to do the reset. Whilst I'm there I'll have him check the electrics - embarrasingly I can't find the battery!

I've also found another garage on the web who say they are true BMW specialists so I'll give them a call too to see if they can hook me up to some proper diagnostics.

Will update later.

if your battery is dead after driving it means alternator is bad and your car was running on battery.

I've had a DIS reset for the gearbox, which highlighted a couple of gearbox ECU problems (noo details though /?#@#!!). I'm ordering my own diagnostics software and cable today so that I can run my own.

On the power front, the alternator seems fine and is generating the appropriate charge. The battery is a little weak in terms of charge retention and was probably not helped by my kids' twin 9 inch DVD players that we had running for about 20 minutes in a parking lot. I'm ordering a Bosch battery which I'll register using DIS and fingers-crossed that will be the end of that.

As always, thanks all for your help and input.

Same thing happened to me yesterday, luckily I was in my driveway. Tried to jump car off, all warning lights and headlamps came on but still wouldn't start. Checked battery. Terminals were loose. Tighten terminals, starts right up now without any problems.

No power out of the blue!

If it's your alternator the you will get a generator error in inpa. When you replace your alternator have th replace the gasket under the alternator bracket and order both, there are 2 different types. Ask me how I know. You got it.

Hi,

My issue turned out to be the battery. Guess after 10 it reached the end of its life. Once replaced, I had no repeats of that wonderful day

For reference, make sure you replace the battery with the right battery - these are ultra heavy duty like those used for cars equipped with stop-start technology. Also, as I read elsewhere on this forum, make sure you use DIS or equivalent to reset the car so it discover the new battery. Skipping this step will shorten the life of your new battery.

Good luck and hope that's all it is.

My situation was very similar to the OP. With a few differences:
- I was 3.5 hours from home
- first indication was not any sort of dashboard indicator that the voltage was below normal (never received this!!!)

- First indication on the highway was at 70 MPH down shift and what felt like a shut down of the injectors, and a DSC on the trans indicated.
- Ran fine after restarting as long as I did not get into it.
- Around town, fine
- Ran the system check multiple times - no problems
- After a football game:

- Stuck in the middle of the road with symptoms exactly like the OP

- with a jump could only get it into a parking lot...

Ran out and got a new AGM battery (Voltage was down to 4 V on old one) to limp it to where I could figure out what to do and check the alternator output
- Not charging (luckily I had some tools with me and my voltmeter)

- Looks like it is the alternator...

AGAIN - NO indication that the alternator was not charging, ever!!! WTF:
-- Even when I ran the System Check.
BMW - Could we have a freaking:

- Voltmeter
- Water Temp Guage

Please???

I'm thinking of putting in an under dash like on my 60's cars...

Water Temp - any Voltage?

So I remembered that there was a way to get water temp, but never did it over the years. Guess I'll try to remember to do that...

http://www.bimmerfest.com/forums/sho...rature+display

Looks like voltage and temp is available in the scroll down menu

Hopefully I can then get it to display easily when running down the road or parked... without going through the menu all the time.

AND a warning light...

If you check INPA you usually get a code for bad generator but on my wife's car the pulley jammed and was smoking which caused the alternator to fail at 140,000 miles. If you have a car 2004 thru 2006 I would replace it and change the alternator bracket seal too. 125,000 you lucky because my 2006 alternator went a little before that.
