This is doing my head in now, not sure what's wrong. Had my car on diagnostic and these codes came up saying lambda sensor bank 1 and 2, had them replaced twice and still the EML is still on? I've had to change my alternator because the battery wasn't charging and my car died and had it recovered. So I'm stumped? I've taken it to an auto electrician and they can't find any obvious faults? If anyone can help id be over the moon!!
Also noticed that the AC pump comes on after start up but no light on the switch in the car? And the fans come on when the car is started up? Is it all related? I need some help!!!
