DS5 Control Unit Communication Error

Experiencing a control unit communication error with my 2012 Citroen DS5 gasoline (186464 km). Engine overheating, check engine light, coolant spillage suggesting cooling system overpressure. OBD scanner points to a communication fault, possibly a defective cable or plug. Anyone seen this before?

Sounds familiar. I've had similar problems with my DS5. Is your car throwing any specific diagnostic trouble codes, or is it a general communication error?

The diagnostic trouble code indicates a general communication error related to one of the control modules. I haven't been able to isolate the specific module causing the problem. Did you manage to pinpoint which control unit was failing to communicate in your case?

Honestly, I didn't manage it myself. After chasing my tail for a while, I took it to a workshop, and they sorted it pretty quickly. Might be worth swallowing your pride and doing the same.

Understood. Thank you for confirming my suspicion. I will schedule an appointment with a trusted repair shop to diagnose the problem further. The projected repair costs are estimated to be around 95€, which seems reasonable. I appreciate your input.
