Hi guys i need help , the rear lights on my C180 went out except the right rear tail light - all bulbs and fuses are fine - on board displays shows no malfunctions and a scanner cant comunicate with instrument ( get in there but fails when i try to pull fault codes ) cant gt into the SAM systems either. i need help

 

hey,
To be blunt, you need a Rear SAM. Just make sure its not full of water etc!
