Noise on startup :/

[phillster]

Hi everyone,
I've noticed that when I start my car from cold I get a rattly noise for a few seconds that then turns into a rythmic rubbing and squeaking noise. It goes when upto temperature. I've had it fully serviced recently along with the aux belt.
Any ideas?
Cheers

Something wrong with the new belt? When you say "had it serviced", would this be the sort of place you could go to and ask about the noise?

I was local mobile mechanic. Havnt been able to get hold of him since, managed to get a different mechanic out earlier he said it was fine, but I know it didn't do it before is very annoying!! He said it's got 115000 miles gotta expect these things, but I like things to be right! Could it be the crank pullyproblem?
He managed to diagnose my sqeeling pulling away problem tho it's a worn clutch release bearing but said don't worry bout it yet?

These mechanics dnt seem to want my money lol

anyone???

Could well be dual-mass crank pulley-itis

If so, you'll either find rust or swarf nearby, take off the cover under the wheel arch for a better view.

Temporarily removing the aux drive belt should change, if not stop the noise.

(If you put your car details in your signature, it's easier for people to help you).

hey, its a 406 hdi 110.
Also noticed a plug that i think he has left unplugged. its nr the glow plugs? do u think i should try plugging it in lol?

[Doggy]

Fuel rail pressure sensor maybe?

Think I'd be plugging it in asap

(Could be useful to post a pic, if you're not sure what it is).

[phillster]

lol perhaps il just plug it in and see what happens! i think its to do with the glow plugs as its attached to them sumwhere. Il take a pic in a min!

I sprayed the pulleys with wd40 and the noise seemed to go i think
