Having problems with your Audi A4 ?
Oil min. warning comes on, checked oil level, on max, shut bonnet, drive for a mile comes back on. changed the oil sensor in sump. now oil sensor fault comes on
This is just a thought , but i would first replace oil pressure switch as this is cheap start to solving your problem , i wonder if you have caused air leak when chnageing oil sensor in sump by not sealing sump correctly ,? the other thing may be you oil pump is worn causing incorrect oil pressure , which may be reason for your oil problems in the beginning , hope this helps , i know what its like when you run out of idea's good luck .
