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

Hey guys, need your help. I have a problem with my Benz GLE Class, built in 2016, petrol engine, around 139,194 km on the clock. The car won't start, battery weakens when starting, lights flicker or are dimmer and a warning light always appears in the speedometer. I have the feeling that it might have something to do with the message error. Went to my mechanic last time but was rather negative. Have any of you had similar problems? How did it go with your mechanic? Would love to hear your experiences. Thanks a lot!

So it seems to me that you need more information I drive a vito 2.2cdi year 2018 639/2 W447 and the ominous error code is U15531 oh yes I have exchanged the roof control unit for one with glasses compartment and Led Bel. exchanged a multi-pole socket of the roof control unit remained free.

Servus, As a rule, this error code indicates a communication error between control units. Of course, now that you have a free connector, it could well be that this also causes the error code. However, if you do not have any restrictions with the vehicle and it does not affect any safety-relevant systems, I would ignore the whole thing.

Hello, was the control unit also taught or programmed to the vehicle or did you just replace it?

I have only exchanged

It's likely that the new control unit needs to be programmed to your vehicle. Control units often need to be coded to match the specific features and settings of your car. I would recommend taking your car to a professional who can perform this coding for you.

The problem is, I've been to Mercedes, they said I won't get the appointment for three weeks. Other garages have said they can't code, do you have any suggestions for me. I'm from Koblenz

Hello community, I drive a V-Class 250d from 2014. Carly shows exhaust pressure sensor. I replaced it and the error reappeared a few days later. I have now had no power 3 times without an error. Stopped, engine off, on again and everything was fine again. No idea what this could be. Maybe someone here has an idea.

The error code C221500 is related to the pressure sensor of the air suspension. It's possible that the sensor is faulty or there might be a problem with the wiring. I would recommend starting with a visual inspection of the sensor and its wiring. If you don't find any visible issues, you might need to replace the sensor. Please update us on your progress.
