Na dont think it does mate, as i had a remap and had a preiod where the battery was constantly running dry. But then i did start to get the hesitation after this so there may be soething like it, might be worth ringing the person who did it.

But then thinking about it the vw map doesnt get wiped so why would the remap?

I think the worst that happens is it thinks all the sensors etc have gone and the ECU has a bit of a fit which throws up loads of codes in VAG COM.
