My (1997 ES) 300Tdi Disco has always been a good starter but has been a bit slow in the recent cold weather. The engine turns on the starter but it can take up to a dozen turns before it starts. The battery is fine - I've checked it with a meter and don't hear any slowing down of the starter before the engine comes to life.
I have heard that the 300Tdi doesn't tend to need its glow plugs unless the weather is cold, so is it likely that one, some or all of my plugs need replacing?
Although I've had this LR for over three years, I grew up with petrol Series IIIs and still have a bit of trouble understanding diesels. For a start, I thought I'd just be able to unscrew the glow plugs and have a look at them (like I could with my spark plugs) but it seems to be a right to-do even to have a look.
I have not been charged for glow plugs at any of my services, so I can only assume I've had the same ones for the last 60,000 miles. Perhaps I should just get them changed anyway; it's probably cheaper than getting them checked.
