Nocking noise on start up

Post by Leon.cassie »

Hi all I have got a problem with my 2005 xsara picasso 2.0 hdi
On start up and shut down I got a nocking noise I have looked over the car and I think the noise is comeing from the rear engine mount but the rubber looks new could this b the drive shaft

You need to be able to look underneath as someone else starts/stops it. It could be the exhaust touching the body somewhere.

Does the knocking noise disappear when you depress the clutch, if so DMF?

The driveshaft does have a centre bearing that can cause knocking when worn. From what you have said I'm not sure thats your cars issue though. Mine have resulted in a knocking under acceleration and a wobbly gearstick when they've let go.

Edit, sorry I read Xantia not Xsara, so what I said is probably not relavent.

Does it sound a bit like a pumping type sound? If it does, then its probably the (camshaft i think) pulley, the one which has the internal bearings which wear out & then it starts to oscillate which causes that sound.

I think your drive shaft centre bearing is worn out.
