I have errors B0090 and B2736. I've already replaced the left front acceleration sensor, but the problem persists. Could you please tell me which part needs to be replaced to fix this?
The screen says "Active bonnet malfunction". I've never had an accident.
GLE W166 2016 2.5 diesel 4MATIC (Austria/Germany).

Before replacing sensors, check the wiring.

I had the same problem. A wire came loose on the right side of the front bumper. Remove the wheel arch and you'll find it in the lower corner.

Since two errors occurred at once, it’s best to check the wiring. Inspect the contacts inside the connectors - there may be corrosion there.
Carefully inspect the wiring near the hinges. I doubt this will be resolved simply by replacing a single part when connecting or disconnecting.
