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. Thanks again Pem24

Bigstoo,Makes no difference wether full tank or half tank,still the same problem. Thanks Pem24

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.:confused:
