Cheers Mick.
It was, indeed the ethanol at the epoxy......horrifying after only 6 weeks max......
Luckily Stuart at ExactUk sent out a replacement sharpish and I fitted it this morning......and she's alive once more.....I did notice that the replacement pot had a different colour (clear) epoxy rather than the black epoxy in the one it is replacing, so hopefully its better epoxy as far as ethanol resilience goes
