What's wrong with your Pug?

[Blue406]

I recently had the chance to get a newer car.

But I stuck with my trusty 406. I know it will get me where I want to go, when I want to. I certainly got one of the good ones

Supa, .......is.......is.........is that you

Where's you been poppet? missed your mutterings and ramblings recently, your not too pleased with black beauty then?

I have saved my car from the 'long goodbye' as it is currently behaving itself and am considering the clutch job next.

Let me know about blanking off the EGR.

Supa, miniman's car is the same as yours and he had a leaking flexible pipe on the down pipe from the turbo, I reckon this could be the cause. When a diesel exhaust leaks you just get a deep rumbling sound not always easy to detect if it's always been like it.

The smell you get would be coming from hear when stationary, when driving it gets blown back under the car.

I inspected mine but had to take off the undertray and inspect it from underneath, lukily mine was ok, maybe they changed the design or make of the flexible in later years and they're not so good?

What's this valve on top the engine they're on about? never heard that one before.

If you have a fuel leak, everything is fairly easy to see once you get the engine cover off, check around the drain off on the filter aswell, I had a leak there once.

So, the smell could be neat fuel or an exhaust leak.

What does the exhaust smell like at the back? my exhaust smells like a light 'dusty' smell, not the heavy burnt dirty smell you used to get on mechanical diesels.

Have your problems become worse since the Petrol episode?

My engine 'runs on' a little when I turn it off, sometimes more than others and it sounds really clanky when shutting down, I would say it runs on for around 2 seconds after turning the key off finishing off with a massive thud as the cylinders stop going up and down.

Supa, to be honest my engine sounds well manky, not a ticking sound but a clattery diesel combustion knock if you like, but the HDi was reported to have sounded more 'aggricultural' than the previous mechanical engine by motoring journalists (remember the HDi was a big step at that time).

I would say if it runs well and pulls reasonably well, returns enough economy and doesn't belch out loads of black smoke then it should be ok IMO.

I don't know if you have it in your D9 handbook, but in my D8 one it says if the engine keeps running after ignition shutdown then I should put it in first gear, press the brake and let go of the clutch to stall it... found that extremely weird!!! But I assumed it referred to the older 1.9L TD model with mechanical injection as I assumed the 2.1L with its "semi electronic" one (anyone know what this actually means??) would stop as soon as the electrics got cut.... hmmmmm

They mean stall the engine in an emergency if it won't shut down.

A diesel engine stops when the fuel supply is shut off (the fuel cut solenoid).

How did they know the CAT was knackered?

I also want to know about this air 'doser'

[Welly]

Ear you are then......................





So Supa, it is your flexi pipe that is leaking? I can't make out if this has been replaced along with your CAT? I was wondering if your middle or back box have failed partially causing a restriction in the exhaust, the baffles can fail and the sound wadding (if used) can block the silencer.

If you ask GAZZA to remove the back section, see if it smells then?

[Welly]

But mine hasn't got one of them You can see on my picture its different there.

[mjb]

How come everyone's engines are so clean and mine's caked with 3/4in of crud?

[mjb]

Mine is filthy actually, but Welly polishes his with Mr. Sheen once every Sunday

I'd have thought it more a Mr Muscle job ;)

[jameslxdt]

that looks like a solenoid that moves a flap like a throttle body, its designed to give the engine smoother switching off, and create a deppresion in the inlet manifold when the egr is activated so the exhaust gasses are sucked into the engine, only the later ones had it as they were EURO lV compliant, when these get stuck they can cause all sorts of problems
im not sure if its called an air dozer, infact im not sure what the proper name is

[Welly]

More emissions controls to look after then

As for my engine, I do actually go round it every so often with AAuto Glym Bumper Care, the green jelly one

It's good for the hoses and black plastic bits.

I am sad..............

[Welly]

It's hard to tell with Diesel's whether your's is 'noisey' or not until I suppose you compare it to others, it must have sounded OK when you bought it Supa?

I wonder if:

• It's got a bit louder because of the Petrol episode
  Has it really done 70K, I'm not being rude as I am sure you checked it out, how about it's had an engine change at some point? did you get a HPI?

[jameslxdt]

i would say the petrol has caused the noise as it excessively wears the injectors, where diesel would normally lubricate them, so they are worn out, so the fuel is not being injected cleanly, and your getting even further ignition lag (what causes diesel knock to start with), hence the increased noise, so i would say stick a set of injectors in it, DO NOT use injector cleaner, as unlike petrol injectors, diesel injectors physically wear out and cleaning them will simply make things worse, also at the same time change the oil, as petrol can get into the crankcase of a diesel engine when its injected at high pressure. due to the nature of the high compression its forced passed the piston rings

if it is the injectors it would explain the reason for no fault codes logged
