Bonjour les gens,
J'ai assisté à une journée de piste le week-end dernier, rien de mal pendant la journée et puis j'ai quitté la voiture garée dans le garage pendant 4 jours. Jeudi dernier, j'ai conduit la voiture et le dysfonctionnement du moteur est survenu après l'avoir conduite pendant environ 1 minutes. J'ai garé la voiture et je l'ai redémarrée, le dysfonctionnement du moteur a disparu et les voyants "vérifier le moteur" et "augmentation des émissions" se sont allumés. Cette lumière est restée allumée jusqu'à ce que la voiture soit complètement chauffée, et je l'ai garée pendant environ une demi-heure. Puis je redémarre la voiture quand il fait chaud, toutes les lumières ont disparu et la voiture semble tout à fait normale. Ce processus se répète à chaque démarrage à froid.
J'ai emmené la voiture chez un concessionnaire BMW local, ils ont dit que cela était causé par une fuite de liquide de frein bouilli dans le capteur d'assistance au freinage et l'a endommagé. Ils ont également affirmé que mon frein était surchauffé et dangereux à conduire. Fait intéressant, je viens d'échanger mes patins avec des patins de course de rue Hawks avant et à l'arrière et rincer mes fluides avec un produit de couple juste avant le jour de la piste. Je suis revenu du concessionnaire, j'ai vérifié mon réservoir de liquide de frein et je n'ai trouvé aucun liquide qui fuit et le niveau des liquides de frein est au maximum.
Quelqu'un a-t-il connu des problèmes similaires et est-ce que le "capteur de freinage" en est vraiment la cause?
Ma voiture est 2011 DCT compétition pack e92 m3.

Quelqu'un a eu un problème similaire ?
The fluid dripping onto the sensor is a known problem, you just have to be very careful when changing or topping off the fluid. There could also be a very small leak.
The generic warning message you got is probably not related to that. It is just that: very generic. Any auto parts store can pull the warning code for you to see exactly what the issue is. It's a free service.

I just had my local auto parts store read my codes to be P1209.(Brake Booster Pump Shutoff Valve Plausibility)
Hi folks,
I attended a track day last weekend, nothing wrong during the day and then I left the car parked in garage for 4 days. Last Thursday I drove the car and engine malfunction came up after driving it for about 1mins. I parked the car and restarted it, engine malfunction disappeared and the "check engine light" and "increased emission" light went on. This light remained on until the car is completely warmed, and I parked it for about half an hour. Then i restart the car when it's warm, all lights disappeared and the car feels just normal. This process repeat for every cold start.
I took the car to a local BMW dealer, they said this was caused by boiled brake fluid leaking into brake booster vacuum sensor and damaged it. They also claimed my brake was over heated and unsafe to drive.
Interestingly I just swap my pads with hawks street racing pads front and rear and flush my fluids with torque rt700 right before the track day. Came back from the dealer, I double checked my brake fluid reservoir and found no liquids ever leaked out and brake fluids level is at max.
Had my local auto parts store read codes to be P1029.
I flushed my brake system when the car was off(no brake assist when pressing the brake petal to flush brake fluids), could this cause possible damage to brake booster or sensors related to it?

I intermittently got an increased emissions warning that would clear if I shut the vehicle off. About a month later the car went into limp mode. I ended up with two new throttle actuators.
Like the above poster said though, it could just mean the car is setting a pending code for the ECM and is generic.
