VZ LS1 Service Vehicle Soon Warning

[A9L]

Heya. My Calais popped up with Service Vehicle Soon warning (not the normal service reminder) along with the sound alarm the other night. did it again today. Using the up/down arrows to reset says "No items".

Did a forum search and I see the oil pressure sensor can cause this and is a very common fault with the Alloytecs, but is this the same with the LS1?

2005. Done 65,000kms.

could be a number of things, best to find a tech 2 or a tuner to diagnose the issue and go from there

Tech 2 said "Fuel rich - bank 1" so two questions:

1) O2 sensor schitzing out? and 2) Is bank 1 the drivers side?

i was getting same svs message then engine would run rough as hell scanned and came back with "fuel lean bank 1" it then went away so swapped 02 sensors around and when it came back scanned "lean bank 2" so assumed 02 sensors replaced them and hasnt come back....touch wood.mine is also ls1
