Peugeot 307 Problems

A fouled plug could cause a misfire, but it should be resolved by changing the plugs. If one particular plug regularly fouls there could be a problem with that cylinder. It could be a number of things causing it, but you’d need to inspect the cylinder to know for sure.

Prices for replacing key fobs vary. You can talk to your dealer about your options, but there are also a number of other places you can get your key fob replaced. You can read more about how to replace your car keys here.

It could be anything really, but I doubt it's the flywheel. If it's a clutch throw-out bearing it should get worse when you depress the clutch pedal.

It certainly wouldn't hurt to change the belt earlier than recommended, but I would be happy to go by Peugeot's recommendation, particularly if you have serviced it as they recommend.

Check the owner's manual, Peugeot's recommended oil is shown there. A 5w-30 premium oil from any of the major brands should be fine.

If the car is under warranty go to your Peugeot dealer and have them trace the earth leak; otherwise have an auto electrician do it.

Buffing pads shouldn't be re-used, if that's what has happened the people responsible should be accountable. There are independent   tradesman who can assess your car and give you a report, one of them is Graeme Cuthbert, who can be contacted on 0422 444 335.

I doubt you have any claim against Peugeot, but you might have a claim against the people you bought it from if they sold it to you with some form of warranty, which I doubt. You got it cheap in the first place because it was in the flood. Cop it sweet.
