Made it ok into the shop with my loose oil plug!
Since they don't get daily parts deliveries from VW
dealership 2 hrs away, I had to go with NAPA.

My old leaking plug had a single copper washer & Bob,
the mechanic, said he didn't think threads were stripped.
He put in an "oversize" plug with 14 x 1.5 mm threads &
washer.  Bob tells me my old plug was a replacement &
he suspects the threads were "worn" in the case.

So now I've got this "oversize" plug & washer & no oil has
leaked in 20 minutes of driving.  Am I home free?
Unless advised otherwise, I intend buying another "oversize"
plug as a spare, along with the washers.
Does all this sound cricket?

Thanks all,
