car juddering. any car experts?

Just thinking out loud (at the lesser expensive possible causes)

Dirty or faulty MAF? / Dirty throttle body?

Air pipe in good condition? (the one that goes to throttle body)

A fuel injector playing up?

Air Mass Meter?

Faulty coolant temp sensor?

Check or replace spark plugs?

You using the correct grade of fuel? (RON)

Or if the symptoms happened very suddenly,
is it a coil-pack gone bad? I don't know
if Peugeot 307s have them. Coil-pack fails and it
runs really rough, misfiring, and lack of power.
Replacement coil packs (one on each spark plug)
are around £30 for my car.

As dopester says, grab yourself a can of fuel injection air intake cleaner, 4.99 at halfords, take off the top of the air filter box, start the engine and spray in short bursts into the air intake, where the butterfly thing is. Apparently some ford's have a special coating on these compontents to help prevent build-up and using this spray will remove it, so look for any warning signs. Or the best way is to get it ultrasonically cleaned but I have no idea of the cost.

Edit: Just realised it's a peugot from a ford dealer not a ford, oops.

I think the real issue here isnt what is wrong with the car, but how the OP can make Peugeot or the dealer feel obliged to find out the problem.

I would consider rejecting the vehicle. The dealer has to prove that the vehicle was in a satisfactory condition prior to sale. Possible arguement - if they cannot show what is now wrong then they cannot prove that it was satisfactory in the first place. If there is an arguement for rejecting the vehicle and getting your money back, then they will be more likely to come to some sort of arrangement in sorting it out. Possibly worth speaking to Consumer Advice or Trading Standards etc to see if they have any advice.

Would also check T&Cs of warranty to see what parts are excluded if any, browse some peugeot forums to see if another pug owner has had the same problem, etc.

Thanks for the replies. The cars back in at the garage i bought it from tomorrow. They spoke to peugeot and they suggested something that could fix the problem that is a cheaper alternative. Theyve got to heat the engine up quite hot, and then they put synthetic oil in it as its thinner and should clear the valves. There doing this for free (no idea how much it should cost?) and theyve said if this doesnt fix it they will pay £200 towards repair.

However the person I spoke to about it said it was quite strange as if it was a ford they would usually pay the whole amount! (so fingers crossed with a bit of persuasion! - they obviously realise theyve got some obligation!)

just an update on this!

They did the engine flush with synthetic oil, and it was a lot better for about 2 weeks, so i phoned them back up and asked them to speak to the manager and see if theyd pay anymore towards the repair. They said the offer still stood of £200 and that was all they would pay (however the engine flush cost £100 so ive got £100 "left")

So i phoned an advice line we get with work (kind of like CAB) and spoke to a legal advisor and apparently as the car is under 6 months, under the sale of goods act, it is the garages obligation to prove the car didnt have this fault when they sold me this. If they are unable to do so (how could they prove it wasnt?!) they must pay the full cost of repair.

So I spoke to the manager of sales on Thursday and as soon as I mentioned legal advice he said I need to send a letter so that they have got everything in writing. He accused the part that they must prove the car was ok as "ridiculous as they couldnt prove otherwise" but said as far as they are concerned the cars are sold with a warranty to fix any mechanical problems - and he doesnt see why this wouldnt be.

So im sending a letter on Monday and they are going to get in touch with the warranty company and find out why this isnt covered and get back to me.

Probably going to take forever to get this fixed but at least it looks a bit more promising now!:j

47,000 miles? Engine problems? I doubt it.

More likely is that it was filled up at Tescos or Morrisons a year ago and never diagnosed as needing a new lamda sensor. Instead it got part-exchanged because it was giving problems, and has sat around at the Ford Dealer until you came along
