Need some help here, if anybody encountered this !
1 week ago: "DBC failure" appears on iDrive, "please drive slowly", and brakes are suddenly HARD as if blocked: Car is brought to dealer (not my dealer.... :( ): they find nothing, and although I complain, they sign off the car, assuring me that I can drive safely with my wife and kids back to Paris (400kms drive).

Now, today, as I park in Paris: a big bang comes from the brake pedal, and here is what falls on the carpet : see picture.

Attachment 68318

I stop the car. Car is now taken on a truck to my local dealer... :|

Now I am totally angry for two reasons:
? 1st: how come such a problem happen on a recent (2006) car such as a BMW with no more than 20000 miles
? 2nd: how come a BMW authorized dealer miss a problem which was probably apparent 1 week ago and which could have led to dramatic consequences (loss of braking power on highway.....)

If any of you encountered this issue, please advise me..... :blink:

There are two springs in the pedal assembly. Looks like one of them broke under tension - probably causing the noise you heard. But I don't see any connection between the spring breaking and the DBC alert message. Certainly a 2-3 year old car with fewer than 20K miles should not have a brake system failure and these springs usually last the life of the car.

The one on the floor looks like the brake return spring.

That said, I'm looking at your clutch pedal - and it looks pretty worn for such a low mileage car? Is it driven heavily in city traffic ? ?

Thanks for the input !
So two problems to deal with ! The Spring and the DBC issue. Now, 20000 miles and a broken spring appears a bit low mileage doesn't it ?

And indeed traffic is heavy over here in Paris ! Maybe I should have one for the auto box !

Bonjour Copello,
Go and discuss with your dealer.
I would argue that it's indeed a bit "early" for such mechanical (spring) failure.

Good luck

I did not know BMW was so much involved with driving safety: locking the brakes is indeed a solution! :lol:

Just for the update:
? The spring apparently was from the clutch pedal... Never heard of such a problem before that as my dealer mentioned (now I must be the lucky guy !!!! o:) )
? The DBC problem is still unsolved...
