Went back to NAPA and they found one that fits. It is the OP6066, made to fit many european cars (BMW, Audi, Alfa, etc). Fits fine, just about 1/2" longer overall.
Does it list the pressure in bars on the part? I ask because I took a used oil pressure switch from an R100 to the VW shop the other day and the only ones he had (several) were almost double the pressure rating in bars.
