e39 540i cutting out
intermitant problem, it cuts out whilst driving, sometimes while waiting at a junction, if in manual tiptronic it starts itself up again but backfires with the unburnt fuel, i think its a relay but as the haynes manual we have in ol blighty doesnt cover the v8 models i have no idea which relay is for the ignition and dme,
has anyone got a pic showing which one i need to check/replace
