Our S40SE 1.8 takes a lot of churning before it fires up - applies hot or cold. We've recently found that rather than starting it in one turn of the key as normal, if you turn it to position 2, then pause, and then complete the start it fires immediately ie as you would expect of a fully serviced 38000mile vehicle. The ignition system, battery etc, fault codes have been checked out by our local dealership and don't show anthing.... Any ideas?
