@skirk i did find this though!!! http://www.ebay.co.uk/itm/VW-Passat...380?pt=LH_DefaultDomain_3&hash=item2a4fc8f0f4
@pkrboo Could be interesting if it is my ECU. Where I've found charge £50 to test and £250 to rebuild !!!
Sounds about right - if you're considering more power do not use plug and play chips or generic maps - always find someone that can build a map for you, every vehicle is different after all.
@pkrboo A great big public thank you. Just a few things to sort now but the big problem was solved by Matt. 55mph up hill. That was taking it easy.
