Default 2008 expert 2.0 hdi problem

Hi all

driving my 2008 2.0 hdi expert van on the motorway this morning at 70 mph when there was a sudden loss of power.

no bangs or smoke but just sudden power loss.

pulled onto hard shoulder and van ticks over ok but when trying to rev the engine it sounds like a bucket of spaners and on about 2 cylinders.

could only drive in first gear on hard shoulder but wouldn't pull up a slight incline.

got a mate to come and tow me home and have van in the workshop.

no warning lights on dash but a bit of white and fuel smelling smoke coming from exhaust.

does this soung like the turbo is on its way out or anyone any other ideas?

any help appreciated.

what code reader did you use

you could do with it on planet/diagbox to check codes and live data

Hi trustme

haven't used a code reader yet. no engine management lights showing on the dash.

I have a cheap basic code reader but probably not much good on diagnostics.

I will see if i can get anyone with planet to give me a reading.

thanks

2 likely causes turbo failed but this does not sound like turbo failure and second is broken rockers.

From your description it sounds like broken rockers as when they break the valves stop opening but as there are 16 in total it can run if some are still intact but wont breath very well so will smoke and the cams will hit the broken parts of some rockers making a racket.

A 3rd but less likely possibility is your EGR valve has fell to bits internally but this makes them undrivable with a lot of smoke but does not usually sound rattly

spot on R406 , sounding like a bucket of spanners would make me think broken rockers.

thanks for the replies R406 and salster

would a compression test with the injectors out comfirm broken rockers?

or any other method of determining wether to go for broken rockers or turbo?

is this a common problem on 2.0hdi engine?

Personaly having had plenty experience of these engines i would go straight for the rockers

Yes its common usually after 150k miles or so

You need the injectors out to get at them as the injectors go through the cover removing the injectors is the hard bit they sometimes dont want to come out!

You could remove the plastic cover/inlet to see in but you can only see half the rockers that way

I found it best with a running engine to loosen each injectors clamps to ensure it will move before dismantling as any stubborn ones will be loosened by the heat and compression pressure.

thanks for the reply R 406

Any particular order in taking out the injectors or any special tools required?

I was having a quick look tonight and would seem to be 24mm head but would be akward getting a open end spanner on without removing fuel pipes first.

is there a special socket that can fit over the injectors without damaging the plastic electrical connectors?

with the injectors removed is it a fairly straight forward procedure after that?

hoping to have a go sometime tomorrow.

thanks again.

once you have taken the clamps off and fuel line then the injectors just pull out but you may have to wiggle them, i would also fit new injector seals when refitting
