GL500, 2013 GL Class (X166) engine 278. 130000 km.
The computer shows a problem with coil 4. I changed the coil, spark plug, injector.
Programmed the control unit.
The computer shows increased voltage on the coil, ignition error, short circuit in the coil.
Checked all the wires - no short circuit in the wiring, everything is fine.
Replaced the coil with a new one, swapped coil number 1 with coil number 4.
After 100 km of driving, the check lights up.
Again shows error cylinder 4.
Please help
Thank you in advance
