940 taking longer to start when warm
Recently my 1996 940 (B230FK) has been taking longer to start (a few more turns of the starter motor before firing happily as usual). It's happening only when the engine is hot and I go to restart it. Starting from normal ambient temperature seems to be fine, I don't yet know if cold weather affects it as we haven't had any cold mornings yet. Any idea what could be causing this? As soon as it fires, it starts and runs happily.
Engine (lambda) light is not on
Last time I had symptoms like this it was the ECT sensor (which i replaced 1 year ago), but that triggered the engine light and it was replaced 1 year ago with a FEBI/bilstein item so I'm doubting it would fail that quickly?
What do you reckon it would be?
