A warning notification has come on in my Audi 2005 A4 TDI S-line, whi8le driving. When I slow down it makes a ping noise, and displays "1km per hour". I selected "Check" and the computer then told me "Oil Pressure". There does not seem to be any leakage, and I had a full service a few months ago. Any ideas?

The car has entered into fail safe mode. It wil not allow the engine to rev high but allows you only to get to a mechanic or to get some oil into the engine. What's the level like? Is there any trace of leakeage?

Is a pressure converting element on the block. Can be leak or shot. Or wire harnes problem worst case. If leak you see dripping oil mostly. Had that 2 times on a car.

Turn off the ignition press and hold the button on the leftside of the display while turning the ignition on it should say service oil on the display pull out the button on the rightside of the display until the service oil clears

i just replaced 1 yesterday your best option is to remove the headlights, bumper, you will see 3 torx bolts both sides holding complete front section, remove air conditioning rad pull round to right hand side without losing pipes, the front section should pull round to the left a little prope with axle stand. draw out a digram of witch way the belt goes round all pulleys. to the left of the water pump (big fan wheel) is the tensioner, to slacken place 15mm spanner on bolt and pull anticlockwise.
