CEL light on. Took to dealer. They tried to look at sensors etc. Upgraded firmware. Total boondoggle. Firmware update broke vehicle computer. Car in safe mode in dealer's mechanical bay for a week. MB Germany writing new code etc. Vehicle in shop for a week. Following all of that - one day after driving home the first time - CEL on again. Took to dealer. New scan - new issues. Now we're told that 2 fuel injectors are faulty and that this is linked to the transmission roughness. New injectors installed. Vehicle has now been running well since return. 8plus days in the shop and why on earth 2 fi would need to be replaced in a vehicle of this low distance traveled is beyond me. |

| 12000 mi | Replaced faulty exhaust particulate sensor. |
