1998 2.8 with PES G2 installed about eight months ago.

Essentually trying to get my EVAP Readiness code to clear, as it is the only one not clearing. Never has given a clear since the G2 install (though may have been that way before).

I believe that the EVAP system is also the cause of an idling issue that I have when below a half-tank...essentually the idle "surges" up and down, and sometimes stalls on deceleration, between downshifts and stopping.

So far have tested the following with VAG-COM and visual inspections:

Block 070 = gives an "EVAP OK" note when tested.

Block 071 = after about a minute it aborts the test. No reason why. The reed indicates that it is closed, nothing else. Can't hear the leak detection pump, but perhaps that is normal.

Have checked the gas cap and that looks to be OK, no tears in the gasket.

Can hear the N80 purge valve click.

Thus before pulling out the drivers-rear wheel well to check the Leak Pump, does anyone have any thoughts of futher "non-invasive testing"?

Many thanks in advance!
