Engine RPM's start high, end low?
Hi
I'm new to owning a BMW and am not having the grandest time, have had many issues with the car in the 1 year I have had it. Hoping for some clarification and assurance. Anyways my car starts up fine at 7 am but the engine rpm's are unusually high at 1200, the car shakes a little bit and then within 40 seconds the rpm's fall to 600-700 and they stay there. Is this normal for the winter? I say winter because this did not happen in the summer and up here in northern Canada its usually pretty cold in the morning. Also side note when I come to a red light the car usually vibrates a lot and RPM's are around 600-700. It honestly feels abnormal, I have never been in a car that vibrates that much. Engine is running fine, no recent service issues. Although 2 months after getting this car earlier this year I heard a noise in the engine, timing chain, oil pan both turbos needed to be replaced 12k repair bill, Goodwill and I paid 2K. The car is a 2013 528xi. Thanks |

What gas are you using? The El Cheapo stuff or Top Tier? Octane? How many miles on the car? |

I've been having a very similar problem. Mine has been vibrating after a cold start in the morning and it will keep vibrating excessively for several minutes. It was getting worse over time.
I took it to the service center to get it checked and they said I had a collapsed engine mount, cracked differential mount and a turbo intake seal leak. Quoted me $3k. Luckily after some research I found that my extended coverage covered the mounts but not the intake seal. Still trying to figure out how the repair that one at lower cost. I haven't gotten my car back yet but hopefully this fixes the shakes. I also have a 2013 528i. I thought both the mounts failing at 75k was weird. I thought it might have been an injector or fuel pump issue. I had been running a JB4. |

My wife's 2013 528i M Sport was acting similar at around 65k miles. The vibration shook the steering wheel and brake pedal when the car was in gear and stopped. She had the extended warranty and took in in for service. I thought that the transmission mount may have needed replacing but the SA told her that afternoon that it was the timing chain. Since it has been replaced the vibration at the traffic light stopped. The SA told her when the chain was removed that it was only a weeks, if that long, from total failure.
Now at the next service the engine mounts were found to be damaged as well. They may have been already damaged and should have been changed when the engine was out to replace the timing chain. Since the service tech should have caught the damage when the engine was out the dealer is not charging for labor and we are getting the new engine mounts at cost. Eric |

If the brackets are covered by some extra warranty I would probably take it into bmw and let them deal with it. |
