Hello and say hello to God in the forum! After 6 years of Renault Abstinenz I bought myself an Espace with the 3.0 diesel engine (Bj. 2003, 180000 km). It’s really great but: Sometimes, I observe, mostly when the engine is “handwarm”, it doesn’t start at all or only after a lot of organs. Then the first km (so 10 to 15) are only very emotional to travel, if you give too much gas he pushes, as if he would get too little fuel. This settles after some time and everything is all the more A “emergency program” is not displayed in the display. Warm-speed it starts well and cold as well. Does anyone know where I could start looking? As a layman I would suspect a “hanging” cold starter, or a non-opening fuel shut-off valve. The “rubberball” at the front right in the motror room can be pumped to a resistance when the engine is standing, after the start attempt or while no resistance is felt. So far I have tried the following: Before 3 T once added an “injector cleaner” and added 2 clock motor oil. (It runs really quieter afterwards and the jerking was completely gone, the above mentioned start problems but only for a week). Would such a cleaner help again? Thank you for all the answers! Ernstl
