Odd Noise... - Kezzieboy - 25-03-2015
Got a weird noise, I'll try to describe it.
It's a fairly high pitched whine. It only happens when cold. It starts at around 1500rpm and builds in volume until stopping abruptly just over 2000rpm. It happens in 1st through 4th, but seems loudest in lower gears. I think it happens in neutral, but can't remember for sure. It definitely doesn't cut out immediately upon depressing the clutch.
Any ideas?

That ties in with turbo spool, anything done to it recently?
RE: Odd Noise... - Kezzieboy - 25-03-2015
Nope, no changes in years. I haven't tried booting it, as the issue is when it's cold, so I don't know if that would make it worse.

Odd. Can't think of anything else it could be off the top of my head.

Definitely try taking the aux belt off and run it
i found my eccentric/manual tensioner was fubar. The bearings were shot and i thought it was crankshaft pulley. Its worth a look ECP sell them for £41 for the tensioner and £45 for the crankshaft pulley...hope that helps
good luck
RE: Odd Noise... - Kezzieboy - 26-03-2015
I hope it's not the bloody pulley, it had a genuine one about a year after I bought it, it's only been ~4 years and ~40k since then!
RE: Odd Noise... - highwayman306 - 26-03-2015
definitely take the belt off and spin the manual tensioner, if it doesn't spin smooth...its that

'Only' 40k on a crank pulley? I'd say you're pushing your luck there.

I second that, so definitely give it a check mate, its easy and takes 20mins to undo and redo and it wouldn't hurt... maybe a couple of knuckles

EDIT - Forgot to mention auto-tensioner could be needing a replacement too (£31 ECP), mines making a ticking noise and have already changed the belt, crankshaft pulley and manual tensioner, so I've been a bit foolish really, you gotta be mad not to replace that...but could only afford the more 'important' parts for now lol
RE: Odd Noise... - Kezzieboy - 02-04-2015
Well the original one lasted 10 years and 76k, so I figured this one would do alright, given it's an identical OEM part. I'll look into it this weekend if I have time.
RE: Odd Noise... - Toms306 - 02-04-2015
Sure it was the original? All the HDi's I've had history with have had new pulleys long before that!!
