I've found this circuit useful to warn of low hot oil pressure over 2000 rpm on an engine with borderline pressures. If you are *certain* this is not the case with your engine, you could disalbe it as others have suggested. But if it were me, I'd replace the "L" board - it is the same one used in A2 golfs/jettas (gas model). In fact, I have a spare one taken from my '88 Westy (gas) which is removed to install the diesel version with my TD setup. I found the warning useful enough to ensure it was functioning with the new engine. You're welcome to have my old one for $5 + postage...
