Yes Sean. That is a common problem. ( sorry, i thought there had been posts about that earlier ) although i haven't seen a corsa with that problem for a year or so.

The first one we did, We drained the tank and cured the fault and it came back with the same problem a few weeks later when we found the waterlogged carbon cannister.

£850.00 wowwwww. Is that what youve spent on it or charging the customer. ??

I also assumed that the water is being soacked up by the carbon filter and then runs back to the tank. ( Ive not seen any official info about the problem )

Tony.
