low compression 2nd cylinder - 2015 F25 - 49k Km
Hi all
i have a X3 F25 - 2015 Model , Diesel , 49,000 Km , 2L Engine i recently find some shakes only on cold start and left the vehicle in service center , they took for a week and said that 2nd cylinder compression is low so every cylinder goes up to 390psi and the second cylinder goes only to 300psi i also have a high oil consumption so i have 2 questions in my mind 1. since its a costly repair , i want to do it after 2 months , so can i drive some 3,000 km with this condition ? 2.can i trust a non BMW mechanic in this matter to do the job ? |

In addition to the one cylinder running low compression, has the service center provided any additional details about the cause? (Burnt valve, failing piston compression rings, etc.)
What has the service center advised-if anything- regarding continued operation of the car or need for immediate repairs? Not really enough info to give you advice, it may be you can easily drive a lot longer and simply keep eye on oil consumption, just no way we can determine. A reputable independent shop that knows BMWs /Euro luxury cars can certainly perform repairs. |

the service adviser said i can personally say that you can drive for a while , but as a BMW we will have to tell you to get it repaired immediately do you think opening the engine is the only solution or some engine oil additives or some engine sealant liquids (found some people using in youtube) will work ? thanks in advance for you time to reply |

Fair amount of labor involved to perform the above. It seems there is physical problem/damage to valves and/or piston ring- that can only be remedied by part replacement. |
