Rough idle when cold!!

[Olliec]

I appreciate these cold mornings aren't helping but recently every morning I start my car it sounds as rough as a bag of nails! It's like a slapping/ticking noise that gets quicker as the revs build up It goes away after 10-15 mins of driving but it doesn't sound pretty... Any ideas??

If your cars have them, alternator clutch pulley seizing.

It's v50 2.0d.. Probably helps lol

Is your engine oil up to specs?

Minimum: 5W30 A1/B1
Optimal: 0W30 A5/B5

And when was it last changed along with the filter?

[Olliec]

It's shell 5w30 and was changed with new filter about 3 weeks ago

I had the same fault no matter the weather. Turns out my alt shaft had bent? for some reason causing the tensioner to bounce a little. I replaced with a recon alt... Now its smooth.

Try taking your belt off and see if the noise is there still or not.

If your talking about that tapping / rattle / ticking horrible noise when you start the 2.0D from very cold then don't worry. The lump, whilst reliable and good for many miles, is often called a tractor engine.

Had a new alternator fitted about 5 months ago so I do hope it's not that.. It's in for a mot in the morning and it's sat on there forecourt over night have asked them to have listen out for it!! Will keep you posted
