have just had a diagnostic check done on the car (as it failed mot on emmisions!!) that only put out about the secondary air injection pump and my lamber sensor was faulty..... both now fixed we have also done abs sensors hand brake fluid and new brakes all round and it still there??? its really confusing at first it was on and off but now it wont go off and when both lights are on i cannot use window wipers or heaters but thank you for advice i will get my partner to have another look at all the rings and sensors again
