CLS 550 W/ Renntech Lowering Module Questions.
I've had my Renntech module for about 1 year now. A long time ago, while iw as driving, i got malfunction reminded on the dash with that car icon. I just basically restarted the car and it was fine.
Just this month, i realize i've been getting that malfunction msg more often. There is no difference in drivability as far as i can tell.
Could any body shed me some lights as why i'm getting this? and how to solve it?
Anybody experienced this before?
Thanks guys
