probably a really simple question but maybe someone could give me some advice.I have a diesel vw polo .I find it hard to start in the morning,the stater motor cranks slowly and weakly.After it has been running through the day it starts fine but after a overnight stop the same problem occurs.I checked the water levels in the battery and they were about half full so i topped them up.Will have to wait overnight to see if thats made a difference.Im guessing otherwise it could be the alternator or plugs.
Any advice would be welcome.Thanks
