    Hi Bimmertech,
    So I have the most wonderful engine in the world. So I let you know before that my BMW 550ix N63 engine has had the customer service package. Well 500 feet away from delaler after package completed check engine light, on a d DT Malfunction. They had given me my car when the shop was closing. Called advisor and said oh it’s the computer trying to reset its self. Drove home and pool of oil in garage floor, oil from front of motor , to rear of motor and alllll the way back to the rear bumber. Hard to start, stall, and an timeing chain jump later it’s back at dealer. Would you let them fix the motor or request a new one?


    • Sound like a major f*$k up on the dealer end,,,the service advisor should have told you to come right back in,,,also sound like the technician didn’t test drive after repairs like it should have a minimum of 2 to 3 miles,,,,ok that being said I would try and get a new engine,,,BMW have lowered the price on those engine to about $6000 because they are the best engines in the world,,,,lol,,,besides if the oil ran out and the timing chain jumped it could have caused a lot more unseen damage inside the engine.

        I really appreciate your advice and coments back, once I win the lottery, I promise to look you up and its vacation time! I will push back, so far they are saying they have approval to open the valve covers to see what’s going on. LoL, they are just trying to find a way out of the mess up!


      • Yes they are trying to cover their ass,,,,I have seen the timing chain jump and it usually causes damage to the intake and exhaust valves

        i need to add my chain have no play at all with cold and warm engine, i call my bmw dealer and he said he never have anyproblem with this engine. In france no problem on the timing chain on dealer !


      • I know some countries have more problems with the timing chain and some countries don’t have any,,,BMW will not tell us why each country is different.,,,maybe that whine noise is the turbo charger whistle it’s hard to tell from the video,,,it doesn’t hurt to have it checked out from the dealer
