Bosch Polocup ecu, car idles correctly, able to do adaption and drives well but when i check dtc's I often get 65535 Internal Control Module Memory Error so i bought another one and took it to the same guy who did original one and he loaded the same map. I installed the ecu i bought and when i started it, perfect, cold start revs slightly higher and drove it untill warm,idle slightly higher but ok. Next day drove car,all fine.
