Does anyone know the difference between A and B in the VIN# on MK1 VW's? I believe this is in reference to the engine.

Incorrect.

The 5th VIN digit indicates engine type via a letter code. That letter code depends on model type and year. For example, the German-built 1984 Rabbit Convertible will be A (lowest output gas engine, 1.8L JH), while a USA-built 1984 Rabbit GTI will have a B (highest output gas engine, 1.8L JH). The Rabbit Convertible only ever had one engine for a given model year, hence the 1984 JH being "lowest ouput". The Rabbit hatchback had multiple engine options, hence that same JH engine being "highest ouput" for the GTI.

For the Rabbit hatchbacks/trucks (the ones I know of):
A = lowest output, gas
B = highest output, gas
G = highest ouput, diesel

Thanks. This VIN is from a 1983 convertible engine I'm thinking of buying. It claims to be a 1.7 and when I do a VIN search it is listed as a 1.7, but, a Chilton manual says the 1983 convertible is listed as having a 1.8 JH engine. The Vin search also indicates the vehicle was made in Germany. As far as I know. The VIN # of the truck I'm driving has a B in that position. It came with a 1.6 gas originally. Are all JH engines air shrouded?
