Video tutorial

This video shows a problem that seems to affect many Mercedes Sprinter owners: ESP errors (including cruise control function), SRS error, side mirrors that do not work or function erratically, indicators that do not work, radio issues, and consequently problems using the phone.

Not all these issues will necessarily occur together, but these are the faults that can arise, and the problem is linked to a relay located in the box in the cabin, specifically number 15, which the YouTuber shows in the video.

It is advisable to purchase an original Mercedes part.

Once the tyres are inflated, turn on the instrument cluster to check that the warning light has completely disappeared from the display. If it is still present, you may need to drive for a few miles to ensure it disappears completely from the screen.
