BMW 1 Series from 2015: MKL and power loss

Valve adjustment noise

|

Loss of engine power

|

Unsteady engine

|

Poor fuel economy

Check engine light on

Hey guys, I'm a bit worried about my 2015 BMW 1 Series with a gasoline engine and just under 60000 kilometers on the clock. The car is showing a number of symptoms: MKL lights up, loss of power, uneven engine running, poor fuel economy and noticeable rattling in the valve area. Nothing serious, but somehow it worries me. Has anyone had similar experiences? How did you deal with it and what was your experience with your mechanic? Thanks in advance and looking forward to your answers!

Hi buddy, experienced exactly the same thing with my 2012 BMW 3 Series. MQL on, power drop, everything exactly as you described. In the end it was the VANOS unit on the exhaust side. At the last visit to the workshop, they said there were problems with the valve timing control, which would explain why the engine was running so unevenly. Ultimately, it can be said that it could be a pretty serious problem, but for someone who knows cars and has access to the right parts, it's quite doable. The repair involved replacing the exhaust VANOS unit. Definitely try not to ignore it, it could be quite expensive. Greetings!

Hey, sounds familiar. Cool that your BMW is back in top shape. Do you happen to remember the cost of repairing the VANOS? And have you noticed any other problems since then? Greetings and thanks!

Hey, yes, I still remember the cost of repairing the exhaust VANOS unit. It cost me €1300 to fix the misaligned timing. Since my mechanic fixed the fault, the car has actually been running like new again, with no further problems. Hope this helps you and good luck with the solution! Best regards!

Hi, thanks for the detailed information. 1300 € sounds a lot at first, but if it saves the car in the end, it's worth it! I'll probably make an appointment with my mechanic next time and have it checked out. I'd better put up with it before something bigger breaks. Thanks again for the exchange and your help! Greetings and always have a safe journey!
