Hi guys, bought a w reg mk1 2.0 ghia a week back, history into it was that it was stolen recovered (not registered) the guy who last owned it replaced the locks, ignition etc.... The past couple of days I have had a look at the car and have found a minor problem of the blower fan being stuck on and it doesn't turn off by turning the knob and the recirc button doesn't work. That isn't the worst of it.

Between 1200 and 2500 revs and only occasionally depending on temperature it is like the car has a lagging turbo or is running on fumes, the car bogs down for about 1/2 a second to 2 seconds and then comes back.

Could it be my ECU about to blow or something simpler and if it is my ECU how easy is it to replace and is it just a case of plug and play?
