I am getting the above fault code.

(Launch actually says 0521 (9,23,5,21) )

Autodata suggests that this is a warning for oil pressure switch/sensor

However!

Coms using the Launch are flaky. I have checked the oil pressure with a gauge (OK) and tried replacing the oil pressure switch (The one on the top right of the engine) on the grounds that it is cheap and easy!

However the fault will not clear. (This "May" be a Launch issue of course. I did say that comms seemed flaky!)

Autodata is poor on this! Nought-o-data strikes again!

Is there another oil pressure sensor on the engine somewhere that may be an issue here??

(Also, has anybody used MultiECUScan on these vehicles?? Is it any good??)
