Hello all,

I've just bought a 2008 Peugeot 1.4 Vti Sport with 76K on the clock and what seems to be a fairly comprehensive service history.

It starts and drives fine, and will happily cruise at 70 on the motorway but I've noticed that once the engine has warmed there is a pronounced rattle noise between 1200 and 1800 revs when driving around town. The engine sounds like a tractor, really rough.
Over 1800 revs the engine note is much smoother and if sitting on idle you can hardly hear the engine its that quiet.

All fluids have been checked and are fine.

I think this model has the timing chain - is it likely to be the cause of the noise?

Any suggestions will be gratefully received!

Thanks in advance,
Mark

You're spot on there, timing chain problems on this engine are a common problem and are well documented on this forum. Do a search.

Just been chatting with someone who says they had the same issue (although I guess one persons definition of rattling may not be anothers!) and he suggested I check the coil packs as they corrode quite quickly and can cause missfiring.
Not being particularly mechanically minded that doesn't mean much to me but is that a possibility?
I always associate misfiring with a big bang and a puff of smoke out of the exhaust and it isn't doing that!

Thanks for your comments!:)

sometimes a slight misfire can be hard to detect, if a coil has gone altogether you will feel it and the dash warning light will come on.
a test i do is just rev the car very slowly, if a pots not fireing well the car will start to shudder at a certain rev.

as said though, would get the chain and tensioner checked.

Hello sir, I had the same problem last month the problem is in the candles you have to change them, if you still hear the noise try to change the coil packs ( not the four of them maybe 1 or 2) use car scanner to detect which one of them is causing the problem.

My thanks to all for your advice!
Just to let know the outcome - car was looked at by a Peugeot specialist and apparently it was the timing chain, or to be more precise the tensioner and guides were knackered causing the chain to stretch. Just had a full chain/tensioner/guides replacement. Luckily the cost was covered by the dealer I bought the car from!
Just got to replace the aircon pump now and the car should be spot on.... :)
