Very strange multiple electrical failure.

Recommended Posts

Hi,

 

It happened just today, after i was about to go home from work. I have pushed the start button, has the engine running, but the car has started to throw the faults straight away after.(dashboard like a christmas tree) 

 

Here is the full list, after the engine has been started.

- Brake sysytem. Drive moderately
- Driving stabilization. Drive moderately

- Restraint system

- Pedestrian protection system

- Flat Tyre Monitor (RPA) failure

- Collision warning failure

 

After i have put into D, and pulled off:

- Press brake to engage gear

- Drivetrain, Drive moderately

- Parking brake only partially available

 

Also noticed, the speedo does not work at all, it does not measure the fuel consumption, and the fuel gauge is jumping up and down depending of the position of the accelerator. There is no power steering at all, and the air conditioning system does not work, the driving mode switch is dead as well. And half of the comfort access dead, i can open the car by hand, but cannot lock it. 

 

Has anybody ever heard/met a problem, like this?  I am going to take it to the service on tomorrow, hopefuly they have available slot for the emergency cases.

Aux belt snapped?

 

Do you have breakdown cover? If it is the aux belt, you'll soon be out of battery power and be stranded.

Possibly battery giving notice to quit if it's original or getting on a bit? Failing batteries can give a scary number of spurious symptoms I gather.

The aux belt is running, i have checked, and there is no error message from the alternator. Do not know the condition of the battery, i have never had any error message regarding the battery. I tried to reset the car, took of the negative and left it for 30 mins, but it did not help.

I checked both fuse box, and the small electronic box in the engine compartment, and the big cable lead, which coming from the front box. There is no water, all dry, no sign of an animal.

Read the error messages using ISTA to get the low down.

Will do it tomorrow. Still do not know where should i take the car. I live in Warrington, the main dealer, Halliwell Jones is useless, but here are three other BMW/Mini specialist, as David Paul, Graham Martins, Prestige. Will phone up all of them...

My bet is a failing battery.  I had the same thing on my old E39, speedo also stopped and random ghost error messages such as self levelling suspension fault.  Changed the battery and all was well.

I wouldn't attempt to drive the car in case you make the issue worse. As @sanjx asked, do you have breakdown cover  for them to come out and diagnose the issue?

Thank you for all your tips and advice. I took the car to the Germany car specialist, which was not far from home. They found a 5A fuse, that has blown, which belongs to the ABS/DSC box. It has been replaced, then has blown again straight after the car has been locked/unlocked. The diag said, the ABS/DSC computer. After all they checked the description of the fuse box, and found the door handle heating(comfort access) is also connected to the same fuse. And after I remembered, the rear-right comfort access does not work at all(first i could not lock, after some days i could not unlock, after died, this was 2 weeks ago). So, what they did now, disconnected that handle, and this solved the problem. I purchased a replacement handle with 12k miles from the USA, was only £120 with the same color a week ago. Good bargain, as a brand new one cost £500, because you cannot replace only the sensor and the heating elements, you have to buy that full unit. :(((  It died due some water got inside, do not know how....

Are the handles really heated?  I thought comfort access just allows the car to lock/unlock itself when you have the key in your pocket?

Not exactly the handles, the inside of it, maybe this protect the sensor from the elements... 

 

nashdm2: Yes, same. But the shame is, you cannot replace only the sensor, which is probably cost only few quid.(like the bloody swirl flaps)

This is some really good information so thanks to @MPowerph for sharing with the forum. Who'd have thunk it possible that a simple 5amp fuse could cause such trauma? And to think BMW put the ABS/DSC circuit together with the door handle comfort access sensor heaters!

As @nashdm2 says, have you checked everything listed in this thread? Checked the fuse? Read the codes as this will point you in the right direction?
