Steam started to comeout the vents - and teh temp went up on the car. refilled with water etc adn same thing happened.
bypassed the matrix by joining the pipes in the engine bay got the car home.
now my question is after having taken out the old matrix and running water through it it does nto seem to be leaking form anywhere - so does this mean that it is ok and does not need changing and that i have a problem elsewhere....

help much appreciated as my golf is sitting in my garage with no dash etc adn i do not want to swap over another matrix if that is not the problem.
