407 Esp asr system faulty speed control faulty

I have a 2006 peugeot 407 executive.

My vehicle is overheating on the ramp. It comes to plentiful red. Master in special service

Replaced the recirculation pump. Changed in the timing when it was opened. The heat of the vehicle was not resolved.

Now esp asr gives system faulty and speed control faulty. Depolution system on the way today

Faulty gave the fault. When the master is changing the timing of a socket or something may have touched something like egr

Overheating can cause trouble. Radiator checked. There is some lowness in the towing of the vehicle.
