w203 front parking sensors

[dannyfiveforty]

My front sensors are playing up. Sometimes they work and other times they just shut down (Two red squares display) I have plugged them in to live data and I have located Two that are not sensing anything at all so plan to replace soon.

How do I remove the sensors from the bumper? Is it straight forward or has anyone got papers to show the procedure?

Thanks
Dan

I believe they just clip in.
