Hello! My parking sensors have started to stop working intermittently. I am getting the following error when scanning using iCarSoft MB II:

- 9009 B8/3 (Inner left front PTS ultrasonic sensor): Sensor is faulty. Current and stored.

According to some youtube video comments, a lot of people have had success removing moisture and getting them working again by spraying with WD40. Unfortunately this didn't work for me so I intend on replacing.

I tried doing a search but couldn't come across any DIY guide and just wanted to know if anyone has changed front parking sensors on the W221 S class before? Specifically, does the front bumper need to come off or is there any way to get the lower grill unlatched so I can reach the sensor without removing the front bumper?

Many thanks in advance.
