Hi. I have a Zafira 54 plate which has had errors 1571 (brake sensor), 1482 and 1483 (fan relay) for last 2 years. It then suddenly developed codes 1122, 1120 and 1550 and went into limp mode with no more than 1200 revs. Had new accelerator and pedal switch fitted and all codes cleared. Drove ok for 2 days but sometimes felt slightly hesitant when accelerating. Then spanner light came back with codes 1571, 1482, 1483, 1122 and 1550 (1120 no longer present) and then intermittently went back to limp mode (usually just after starting car when slightly warm) however, a simple lock and unlock of car temporarily resolved this. I have a feeling it could be the ECU. Is anyone able to offer advice please?
