Proud original owner of a VW 2.5 petrol 4T auto 1999 Caravelle. Only done 110K. Found the community whilst searching for a cure for a stalling engine when at operating temp; this is great CAR to drive as I like to throw it around. Ex hillclimb champ. They may yet bury me in this vehicle.

G'Day, people, hope you can help with this dilemma.
1999 VW 2.5 petrol Auto Caravelle
When the engine reaches operating temp it will cut out whilst idling, sometimes, yet runs perfectly well whilst driving. To stop this I have to keep the revs above 1300 rpm, whilst idling, instead of the normal idle of 850rpm
Thinking it may be petrol pump relay # 30.

Any help would be most appreciated, lockey.
