Hello all,
My car has started to start rather slow (M59, 1.6HDi, 90bhp, 2007, 9HXC engine, 80k miles). It started to take a lot more number of cranks than before, i.e. ~5-7 to start, when the engine is cold, not necessarily when temperature outside is cold. It starts perfectly when the engine is warm, probably half a crank.
There are no errors with Lexia/Diagbox. I have a tyre pressure monitoring system (external on the valves) and it also gives me the battery voltage real-time. I also double checked the values with a multimeter. Once the car is running the voltage of the battery is ~14.20-14.35 if nothing is switched on and ~13.9-14.1 with lights and heater on. It seems, that the alternator is working as it should. The battery is ~1-year old, BOSCH S5 (63Ah or 610A). I started measuring the battery voltage before starting and it seems that is pretty consistent ~12.3-12.5. A bit lower than the required 12.65.
Does this point to a potential lazy/end-of-life starter motor or should I get a new battery for the reason that it is always below 12.65 and maybe there is a dead cell (battery is sealed). If the starter motor was easy to access I would have replaced it myself already, but will probably have to go somewhere to get it replaced.
Any help is more than appreciated.
Cheers,
