Malfunction when starting the Benz GLE Class 2016: symptoms, causes and suggested solutions

Hi, had a similar problem with my C-Class (built 2017, diesel engine, just under 117,000 km) a few months ago. It definitely sounds like the control unit has a fault and is sending incorrect signals to the BUS system. In my case, it was actually the control unit. It was constantly sending false signals to the BUS system, causing all sorts of warning lights to come on. The battery and lights were going crazy. The mechanic had to replace the control unit. It was a relatively serious problem because the control unit is a kind of "brain" of the car. Without it, nothing works properly. So yes, get a mechanic to confirm that the ECU is faulty and may need to be replaced. I hope this helps and your problem is solved soon. All the best!

Hey, thanks for the detailed answer. It looks like I wasn't wrong in my thinking. It's quite annoying that things like this happen, but I'm glad we have forums like this where we can exchange ideas. Can you remember the cost of the repair? And has anything else come up since the ECU was changed? Thanks again!

Hi, I'm glad I could help you. Yes, I do remember the costs. I actually had to dig deep into my pockets to repair the control unit, which was defective and had sent the wrong signals. The fun cost me €1000. Since I went to my mechanic and he replaced the control unit, everything has been running smoothly again. The problem with the message error has since been resolved. The car has been running like clockwork ever since, no more warning lights, nothing. It was the control unit that had caused all the problems after all. So, despite the high costs, it was definitely worth it. Hope it goes the same for you! Good luck, buddy!

Hey, thanks for your feedback. Now I at least have an idea of what I can expect from the mechanic. 1000 € is a lot of money, but if the car runs again afterwards, it seems to be worth the money. I also hope that my problem is also limited to the control unit, so that it is solved after the replacement. Of course I will hope for the service of my mechanic. Thanks again for the help! Wish you a safe journey at all times!

Hello everyone, Can someone help me, my parking light is permanently on and windshield wiper and light switch is without function Event B1113 Error in CAN communication with the SAM-F. control unit - current and saved

Hello, This sounds like either a cable connection is faulty, more precisely a so-called "Can-Bus" connection, or there is a problem with the SAM control unit. What kind of vehicle do you have? Has the vehicle's battery been changed recently?

I have a 2005 Mercedes CLK W209 220 CDI and the following situation has arisen: When replacing the handbrake, brakes and coupling rod, I forgot to switch off the ignition. We then tried to bypass the car with an Audi A5 3.0 TDI. The positive cable started to smoke, apparently it was defective. Since then, the parking lights and interior lighting have remained permanently switched on. In addition, the light switch and the windshield wipers no longer work, and the high beam and handbrake symbols light up in the instrument cluster. I have to disconnect the car battery every time to prevent it from draining. I bought a new battery, but the car still won't start. It only starts up to the ignition, after that nothing happens.

So it works with the old battery but not the new one

It sounds like there might have been a short circuit when you tried to jump-start the car, which could have damaged the SAM control unit or the CAN-Bus system. I would recommend having a mechanic check the SAM control unit and the CAN-Bus system for any damage. This is a complex issue that requires professional diagnosis and repair.
