Angry My M3 Journal - Discover Problem

Hey guys, today when I park my car in 1st gear and turn the engine off. Then I step on the brake, and then all of a suddently I feel my break is so hard and I can't press it down. I turn my engine to ignition 2 and I cant turn the gear to 'N' or netural. I CANT START THE ENGINE. I repeat that like for 5-6 time and still cannot change the gear to 'N' (I DID STEP ON THE BREAK BEFORE TRYING TO START THE ENGINE) I ALMOST FREAK OUT! Then I step on the break really hard and this time I can depress it and the gear let me change to 'N' and I can start the engine. However, I notice some noise like 'ti' 'ti' 'ti' from the engine that I didnt hear before. ANY IDEAS WHAT IS WRONG WITH MY CAR? THANKS

Is it a knocking sound coming from the engine?

It's not just about driving fast. It's about driving at exactly the right speed.
Twisting through the bends braking - steering - changing gear - accelerating - all at the right moment.
Getting this to flow smoothly calls for timing, experience - and the right equipment.

Sometimes you'll decompress the braking system in which will make the brake pedal feel hard and unmovable. Once you start the car, it will behave fine and the brake pedal will have normal travel.

I'm not 100% sure but M3s may require you to exhibit braking force during engine start. Because the brake travel has been decompressed, you can not exhibit the correct amount of pressure to trigger the "brake is being applied" signal the car needs to start up correctly. Eventually you were able to get the signal to work.

I would suggest taking it in as any issues related to braking is serious. However, my hunch is that this is a minor incident.

BTW: Decompression of the brake pedal system is caused by repetitive brake pushes when the car is off..

Okay, thank for the info guys. I just drove my car around town and it seem like normal now. However, I do still hear some 'ti' 'ti' 'ti' sound come out from the engine though. My car now only have 350 miles on it....

Is the "ti ti ti" sound at low RPMs? Take it to the dealer to get it checked out.
