Engine control lights

Antara Bj, 07 Diesel / 2, 0 cdti / 150 ps circuit , approx. 61000 km the following problem ! My engine control search always goes on, so 4 to 5 times a year. Sometimes after 2 to 3 weeks, then again after a few months. This is already going on for some years. Drive then to my Opel workshop to make errors read out. It always comes out the same thing: intake temperature with exhaust temperature not compatible or not plausible. Error can then simply be deleted in the readout again w It was exchanged during this time: air mass meters, lambda probe, any other fuehler and probes. Temperature was also measured in the exhaust. Workshop doesn’t know any more. Car continues normally when the light goes on. Also, the lamp only goes on when you start a car, not while driving. If someone has a solution, would be very grateful.
