I have an 05 Audi Tdi and recently the oil pressure warning light came on. My engine has also been making a deep rattling sound which is getting worse. I took it to my local garage who advised that the oil pressure is fine and they cannot see why the light would come on, they also couldn't find any obvious reason for the loud noise coming from the engine and are investigating further.
Can anyone help with this? Is it a known audi fault or has anyone had anything similar?
