CLA Cruise Control Issue

I'm writing to inquire about a problem I have encountered with my 2015 Mercedes CLA, gasoline engine, with 118037 km on the odometer. The cruise control has ceased functioning. An error message is displayed in the speedometer, and the cruise control does not engage. An error is also stored in the error memory. Could this be a faulty system Could the throttle body be the cause

The 2015 Mercedes CLA's cruise control stopped functioning, displaying an error message on the speedometer and storing an error in memory. The issue was suspected to be related to faulty system components or possibly the throttle body. Upon inspection, it was determined that the problem was due to a defective cable or plug connection, which was repaired at a workshop, resolving the cruise control issue.

Did this summary help you solve your problem?

Cruise control kaput, huh Hmmm Error in the speedometer and stored in memory Sounds like more than just a loose gas cap, doesn't it Any chance it's a car electronics gremlin Did you check the connections Plugs, cables you know, the usual suspects

Thank you for your swift response. Regarding the connections, are there any specific areas I should focus on Are there common failure points within the cruise control system's wiring or connectors that I should inspect more closely I am wondering if there's a way to fix the non-functional cruise control myself.

Specific areas Well, without a proper scan tool, it's tough to pinpoint. But yeah, connections near the wheel speed sensors and the engine control unit (ECU) are prime suspects. Honestly though, with a malfunction like that triggering error codes, chasing wires can be a rabbit hole. Is it really worth the hassle Probably best to get it to a workshop, they can properly diagnose it.

I appreciate your input. I took your advice and had the vehicle inspected at a workshop. As you suspected, it was a defective cable/plug connection. The repair cost me 95€. Now the cruise control works as expected. Thank you once again.
