Xc70 D5 2005 slow start only when cold

[OWF]

Hi there,

I have had my 2005 D5 Xc70 for just over a year now and have noticed on the first start up when it is colder outside it is slow to start and sometimes takes 2/3 attempts waiting for the glow plugs to go out each time.

Once it has been started I have no trouble starting for the second time even if it has been run for only a few minutes and not even up to temperature. In the summer or when warmer the first start is much better and is no problem at all.

I have looked to see if any injectors are faulty as I have seen a lot of starting problems being related to this however after completing a leak back test yesterday I don't think the injectors are the problem, as they all returned the same amount and were under the 40ml Volvo recommends.

I am now thinking it could be glow plug related as the glow plug light on the dash can take around 6-10 seconds to go out, and even when trying to start on the second attempt the light takes just as long as the first time which seems unusual?

I pulled 3 out of the 5 most accessible glow plug leads out (Cylinder 1 / 2 / 5) to see if on a cold start it would make a difference, but it started within the same amount of time as I have been experiencing. I may have been unlucky though with this test and left the only working glow plugs in..

I would like to get some other opinions on this if possible as although the warmer weather is hopefully coming it would great to get this resolved.

Thanks,

Ollie
