S80: Engine - Noisy idling

inaminute23 · Feb 4th, 2019, 13:36

Hi, I have a 57 plate S80 D5 (103K on clock). When idling it is very "throaty/grumbly". If i give it revs to over a 1000 it sounds normal. The car seems to drive normal and fuel economy seems fine. The noise does dampen down after the car has warmed up. Does anyone have an idea what the issue is? Thanks.

I had a similar problem. Turned out to be the glowplugs.

Cheers mate, was it a quick diagnosis?

Yes I took the car to my local mot centre who connected their diagnostics machine on it. Mine came up with glowplugs circuit faults for cylinder 1 and 2 but I changed all 5.

Mine is almost certainly the drive belt tensioner pulley. Hopefully it is not an expensive fix. I can get the part for around £45

It can be if you don't get it done soonest.

This is the achillies heel of these cars, that tensioner fails, shreds the auxiliary belt, bits get into your cam belt via the open bottom of the cover and wrap around the cam belt. The best you can hope for in that event is £2000 worth of cylinder head rebuild, the worse, a new engine.

Something that needs doing not thinking about.

It was diagnosed as the alternator pulley (flywheel pulley). It's going in for repair on Friday
