hi i dont have much details at the moment however my mates van is giving problems its a 2000w reg sprinter (facelift 311cdi) model and it has an intermittent problem of only going up to 3000 rpm until you switch off the ignition then start again may be ok for a while . also what he has noticed giving more problems when carrying a full load (delivering parcels) .oh yeah its a LWB if this makes a difference? he went to his local garage they are saying could be turbo or may be exhaust ???? any ideas ????
please help as he is pulling his hair out
TIA
