So fine starting when cold but when warm turns over and over then judders when eventually firing. lvedHave had x2 clutch and flywheel transplants - Not resolved. Gearbox and engine mounts - Not reolved. Could it be this.... http://cgi.ebay.co.uk/TDI-PD-Diesel...s_SM?hash=item2ea7818c94&_trksid=p3286.c0.m14 Think it did it before fitting this unit but since fitting its got worse. Could the sensor be knackered anyway and this unit has just made it worse? Q. Is this unit telling my ECU the fuel is cold when its hot and causing it to start sh1t? It only EVER judders when warm. ALWAYS starts fine when cold. My only other thinking is for a re-map. Could the ECU be on its way out? Please Please help. So fed up with it.
