Hi , I have a 2012 C63 wagon with 60k miles. Owned it for 5 yr and love it. Had hassle with ABS/EBD etc etc etc . Managed to get a s/ hand abs module for £180 and got it coded for £70.

Latest problem is with the ultra sonic system setting the alarm off.
I've searched for spiders and flies, but am thinking it could be electrical. Anyone had experience with false alarm triggering. ?
(I isolate it with overhead switch, but it's a daily faff. )
Thx

Hey! This could be a far stretch but it’s what happened to me: the top seal of the windshield began to give up and made holes. So whenever it rain the drops would get in and trigger the alarm.

 

Much appreciated. I'll check that out.
