Hey guys just recently bought my first discovery DII 03. Frigggggen love the car. I have been trouble shooting the little things using this forum etc.. but i've finally had a need to post. I have this weird croaking rattly noise at idle. I'm no mechanic, but I'd like to know if its something easy I can handle or do I need to take to the mechanic?

Its not that loud, but listen for a croak/rattle. The car runs and drives fine other wise. So idk...

Edit: fixed the video link. Should work now

Sai pump?

 

Thanks for the quick follow up . My SAI pump is loud at cold startups do a minute or so. You think it's related? I did have a fault code P0455. I changed the gas cap and cleared it. I haven't had the service light come on In a week or so. I appreciate the help

 

Get under the car belly up when idling and check if it comes from heat shields missing nuts on top of catalytic converters/mufflers. Watch your nose, could get toasty.

 

A frog ...................... or maybe the person you have recently run down not quite 'croaked' yet sorry, couldn't resist.

 

Ok will see if i can find anything. Good thing I have a 2" lift. I was on rave, and I just want to make sure where catalytic converter is. The noise is definitely from the front, and I think its passenger side more. Does that help ID the croaking?

 

Just an update. It turns out the shaft holding the water pump was causing the rattle. It had broken off and was barely hanging on. I had to replace the entire water pump. In addition, the grinding I heard at ignition was not the solenoid and/or flywheel. It was the water pump as well. 2 birds with one stone!
