Latest suggestion is that it's the EGR valve going through a self cleaning cycle

Is this the petrol engine that injects petrol straight into the cylinders ? They seem to have dropped that engine but other makes still do them -VW/Audi Are they all rubbish ?

I was wondering about the crank pulley Amazingly it made the noise twice in one day today which is very rare. Never from a cold start .I'm not going to worry till it gets worse , it won't cost me as it's on lease I like the car , superb cruiser with the 6 speed maual box and full spec Full marks for guessing Lovekyns .I live 1 mile from the Ruxley Lane branch. Open one day, boarded up the next. Shame as quite liked them , well , compared to my local Renault (Rubbish)/Nissan/Peugeot franchise........ Any suggestions where to take the car now ?

I suppose for a real bargain price it could be a good buy ?

Don't know .It never clicks for long enough to get out , open the bonnet and investigate !

I run a 2006 C5 2litre HDi Exclusive Estate and once every week /10 days when I start the engine , there's ticking/clicking noise from the OSF engine area which lasts for 10 secs max. Everything seems to work Ok . There's little point in taking it to a garage as it won't misbehave to order . Any ideas ? Is it serious ? Fortunately it'a lease car. Only done 10K miles I was very pleased to find this site as my local dealer was 1 mile away but has gone bust and I now have no one to ask questions Dave
