Cold Start

Narek_M4 · 03-12-2021, 11:10 AM

Has anyone else's cold start become quieter ? For some reason the startup on my 2020 M340 is hella quiet compared to before. Wondering if this is the same for anyone else ?

The weather warm up where you're at? That can cause it to be quieter.

Not really much of a cold start if it's warm out.

Yes. I got an update at the dealer. No more loud cold start. Starts like normal. But I am able to start with valves open on s+
