Mercedes E Klasse Rain Light Sensor Problem

Sounds familiar I've had similar issues with my E Klasse Check for bubbles forming under the gel pad of the windshield where the sensor sits That's often the culprit Is the windshield original or has it been replaced

Interesting Bubbles huh I'll definitely take a look The windshield is original as far as I know but I bought the car used so no guarantees If it is the bubbles what's the fix Is it a DIY job or am I looking at a workshop visit

If it's bubbles under the gel pad the sensor is malfunctioning I recommend a workshop visit It's an electrical fault and messing with the sensor yourself could cause more issues They'll likely need to replace the sensor unit

I appreciate the insight I took it to the workshop and you were spot on Bubbles under the gel pad New sensor error cleared and everything's working again It cost me 62€ Thanks for pointing me in the right direction
