Hey Clan,

I don't think mileage is to be considered, as it has 153.000 km, so still less than 100.000 miles... Glow Plugs are probably the way Togo.

What is your experience when it comes to removing glow plugs on the D5? Are they easy to extract or is it like on VWs and Fiats where they will end up broken i.e. snap off?

Cheers

No problem yet with a D5 glowplug... i mean getting them out, also very reliable very rare any need changing what ever the mileage.

Damien in case it helps, I had a MK4 Golf and yes the glow plugs were a nightmare! The Volvo is fine, I replaced mine a few weeks ago on a 2011 V70 D3 (5-cylinder 2L) and it was very easy. I didn't use penetrating fluid, instead I made sure the engine was hot. Ensure you have the correct tool and that it fits, and for easier access remove the air pipe (red) that sits between the airbox and the resonator. Also don't use your hands to remove the electrical connectors, instead carefully use pliers holding onto the cylindrical section of the connector.

Cheers. That is why I am little surprised, that my D5 had a new set fitted in 2022 and is now already failing - at least as far as I can tell. The parts were installed by Volvo and are AFAIK Volvo parts...

Removing the intake pioe is no hassle. Have done it a few times - last to do the alternator freewheel. But thanks!

I'll measure them first and then see what the results are. Maybe they are all fine, which would then probably either a faulty injector or something else...

That's the way to go. If the glow plugs are fine, then its pointless buying another set wasting money.

Exactly. I mean, abput 100 quid for 5 new glow plugs isn't much but of course a lot of hassle for something not broken/dead.

test them before buying new loads of youtube vid on how to do it with a multi meter.

Definitely test them first! I wasn't advocating to have them replaced, just that if you were you'll find it's easy with a hot engine and the correct tool.

So the reason I changed mine was due to having glow-plug-related error-codes for cylinder 2 & 4 and sometimes 1. In the end my plugs were all ~2ohms except for cylinder 2 which I think was ~19ohms. But it seems the main issue was that at some point in the past a cowboy mechanic installed 7V plugs when they should have been 4.4V

If you haven't done so, see if you have any error-codes...

Did your car show the check engine light or were they hidden codes?

That's the next step. I hope to be able to do it on Saturday, if the weather is okay...
