I took it back to make them aware of this and they have said they will collect it from my work place tomorrow.

Anyway, i got almost home and the noise (suspected turbo) gets worse and worse. When i get home i pull into the drive and suddenly the car revs and revs at about 5000 rpm (to be honest i didnt look).

So what would you do??

Switch off and take the key out? Nope did that and car kept reving at 5000 rpm.

Disconnect the battery? Nope did that and the car kept running?

I tried to contact the dealer to find out what to do and they had gone home!!! by the time i put the phone down, the car is still reving at 5000 rpm however there is now a small fire on the underside of the car!!

What do you do now?

What car do you have Mate?

Diesels work on compression rather than a spark igniting the fuel .

i think the squeal noise was the turbo, and i think the turbo my have exploded in the end, but the cause of it reving itself to death i have no idea.

I know one thing, its good for constipation

The car carried on running regardless of ignition turned off, Battery disconnected etc because it has a Mechanical fuel pump rather than an electrical one such as most petrol version engined cars have.
As to why your problem occured, i`d like to see the car and have a look before making a comment.!
You would be better off taking it to a decent garage and telling them the problems so they can diagnose it properly for you, once you get a report, go back to the garage who did the work for you and take it from there.
By the way, what caught alight underneath the car?
Oily rags?, Did the correct fuel get put in the car ie diesel and not petrol? Maybe your catalytic converter was blocked and the back pressure kept the engine running!

it had just come back from the Peugeot dealer! you would assume they would be the best placed to determine the fault.

The thing i dont understand is that it should have a fuel cut out somewhere. With a turbo its a vicious circle, rev the car, turbo goes faster which makes the car go faster, hence the need for a rev limiter. But thats supposed to be linked to the throttle!!

Cars only have a fuel cut off switch that cuts the fuel in the event of an accident and you have to push the button down to start the fuel flow again.
What year is your car?
I drive a 406 diesel and before that i had a 405 diesel and i would never let our local Peugeot dealer touch my car after my last experience with them!

What i can`t understand is why the car revved so high.
It sounds like a sticking fuel pump cable to me, get the throttle cable changed.

From the sounds of things you've had several issues at the same time.
Firstly the throttle got stuck open causing the high revs.
Then the fuel solenoid (which is what stops the engine running when you turn it off) got stuck open.
Your turbo would have raced, your oil temperature would have gone up too.
You've said you've had problems with the turbo, probably the bearings which would have created an excess heat and the fire.

A colleague's Audi did a similar thing on the M25 in the middle of the road works, the lining of the engine compartment didn't so much catch fire, as smoulder and drip off, although I think the bonnet lining did catch light.

Nice engine to work on, the old 1.9TD
Had one in my Xantia, filled it with water during a flood, and once I drained it all, it still ran.

looking under the bonnet in mine i looks like they used a shoe horn to get it in.

Funnily the main reason for buying that car was the engine and ive had several things go wrong with it and now this major problem

Yeah, it used to be like that with the 1.8D in my old 205's (shoehorn that is, not problems, never had any problems)

Sounds like you have something of a lemon.
Get the RAC or AA to do a full report on the car to take to the garage and demand they put right.

A friend bought a Corsa from a dodgy Vauxhall dealership in Basingstoke.
Was originally sold by them as new to an old lady and always serviced by that dealer.
My friend bought it at 2 years old.
We had a particularly cold winter, and it died on her as she pulled out of her road one morning.
It turns out the water pump wheel had sheered off, causing the cam belt to snap and damaging the engine.
The dealer said it was her fault and would be £1500 to repair, but as a good will gesture, they'd knock £200 off the price.
We took it to a cheaper garage to get the work done and straight away he pointed out there was no antifreeze in the coolant water, and rust in the water pump.
Suspecting that it had been running on just water since it's first service (while owned by the old lady) my friend got an RAC report done, which confirmed that due to long term running without anti-freeze there had been corrosion, and the water had frozen around the insides of the pump, causing the wheel to sheer off.
The dealership did the work for free, although they weren't very happy when they said it was done, and my friend had another RAC report done which showed they'd done a poor job, so had to do it again properly!
She got the dealership to pay for one of the RAC reports, and the other one was money well spent.

good idea getting the AA or someone to do a report first.

I think the only lemon was the numpty who did the work today!!
