my 2000 a4 the oil pressure seemed like it never got above 50 ,on my 2002 6sp i notice the pressure went up to almost 80 tonight .is this normal ?

 

With the ignition on and the engine off, does it read any oil pressure? If it does, your oil pressure sensor needs replacing.

 

Check your DIC . It is probably reading 130.

You need to replace the oil sensor.

I believe it is a 1 1/16 six point deep socket that is needed....

The fix should take between 2 - 4 hours depending how handy you are or aren't .
With the DIY anyone with two hands that can read English can do it in 4 hours.

NOTE torque the new sensor to 15 foot pounds... more than that will result in premature failure

NOTE many claim the replacement aluminum housed unit fails in a few months... There does not appears to be any brass based repalcements available form any source. One of the suspected causes of failure is not cleaning the electircal connector of residual oil that leaked thru the old faulty sensor.

NOTE when reinstalling the intake torque the bolts in two passes..first pass 44 INCH pounds, second pass 89 INCH pounds
Start on pasengers side middle bolt, then drivers side middle working your way alternately to the front and back while also alternating tightening the driver and passenger sides...
