peugeot 407 2.0 hdi engine noise , tapping /ticking

Post by simonfitzp1 »

i have a 2008 peugeot 407 2.0 hdi , rhr engine which has developed a ticking/tapping noise when it warms up. i've changed the oil regularly every 3000 miles , had new injectors and cleaned the egr valve . the car has 96,000 miles . is this a tappet or chain sound ? any help is much appreciated !!!!

Hi, and :welc: to the forum.

What could help to narrow down the problem is if you post the VIN here. It will allow a Moderator to look up your car to see exactly what she had when she rolled out of the factory. For security reasons it will be obscured so only Forum staff can read it.

Try and see mechanic let him check the timing belt or chain do fast

Damned if I can find them now but there have been two similar problems recently that were - in one case at least - the alternator clutch.

I've run it without the belt , same noise , I'm thinking 1 of 3 things bad lifter , slack chain in the head or crank pulley but it seems to be up higher , I've ordered 4 new injector seal washers incase it's those , I'm really worried the engine will just go bang on me , I rely on my car a lot for work and travel to see my daughter and I'm not flush with money so need a fix lol

Steve may have been referring to this post here relating to a Citroen 2.2HDi on a Citroen C8. Have a read watch the vids and see if it could apply in your case.

What may help is one of these

A diagnostic interface between ear and vehicle to precisely tie down the source of the ticking
