Please help. I have RR 2.5 dhse w reg (BMW engine). When used daily no problems starting, however when left for approx 1 week, will not start straight away, needs 4 to 6 attempts to start it. Thinking it may be glow plugs. Any ideas.
As your engine is an indirect injection one,from cold it will need glow plugs to start it.Every morning - so its probably not them,fuel running back because of perished leak off pipes or a slow cranking speed because of low battery voltage are much more likely.
to eightinavee,
thank you for reply,you've probably answered my question,I swapped the battery a few weeks ago & noticed the new one had a lesser cranking ratio.
