Hi all, I have a 2003 ML 270cdi with auto box, yesterday I went to start the car and as soon as I touched the foot brake to select drive the ESP/BAS light came on and the transmission is firmly stuck in park. I have managed to 'Beat' the light by 'snatching' drive as the engine fires up, I can then drive the car as normal but the minute I put it into 'P' thats it transmission locked. Having read all the related threads it seems to point to a faulty brake light switch but no one else has mentioned the transmission lock out. Battery is fully charged and brake lights are working fine. Any help or answer would be appreciated.

Locking to P can happen with faulty b-light switch. Just change it DIY: Mercedes ML Brake Light Switch - YouTube
