Just got lumbered with a 54 plate 307 sw 1.6 hdi, there is a major lack of power, prob about 30-40 seconds 0-60mph.

I've seen similar threads but I thought I'd see if anyone has any ideas where to start, I can't see that replacing any of the filters could make it that much better.

There are no lights on the dash or smoke from the exhaust, unless there's a pipe off somewhere (not had a look yet, wanted some ideas before looking in the morning) could there be anything else that could affect the power this badly?

Any help to point me in the right direction would be greatly appreciated.

There are a few of things that can cause this, but there are many others.

- Turbo Failure
- Diesel Particulate Filter issue (the 1.6 and 2.0 HDI versions usually have this during the pre facelift era)
- Injector or injector pump issue
- Fuel filter blockage / fuel pump issue

You usually get a depollution fault for many of these problems, however I would just check no hoses in the engine bay have blown off or obviously not connected. I had one of the hoses come off causing a pressure problem so it is worth checking.

The best advice is getting it on a diagnostic with peugeot planet to look for faults within the engine ECU.

1.6 no power...

Sounds just like what I had...
the small rubber elbow that supplies vacuum to the turbo was off (some d#$%head knocked it off - read me). Two second fix. it's below the turbo on the right side. A rigid plastic tube brings the vacuum up close and the elbow is just that, an elbow..However my elbow was swollen a bit and I was not at all confident it would stay in place...so I took the coupla minutes to put a spring clamp on the two ends. When you put it back on you will get a depollution fault showing for, in my case, three days. Every time I have touched the turbo piping I get the same error...all good now though...

Good hunting...

Cheers David, will have a look in the morning, hopefully (fingers crossed) it will be that or something similar.

Matt, as far as turbo failure is concerned, wouldn't that mean it would smoke? As it doesn't smoke I was hoping to rule a faulty turbo out.

The previous owner did say they had the Diesel Particulate Filter done on it.

Think It's Turbo

I'm pretty sure it's the turbo not kicking in.

Does this mean the turbo is knackered? I thought if the turbo goes you get black smoke. The car isn't smoking.

Could the turbo be an electrical fault? There are no lights showing on the dash.

id check that, just drop clamp off and take it for a quick test drive.

Does the turbo work electrically? May sound like a stupid question but never worked on one before.
Could it be a relay, fuse etc...?

No boost DOES NOT mean the turbo is stuffed

The turbo is controlled by the ecu but it needs good vacum to the control solenoids no vacum no boost as the vacum is used to close the wastegate if wastegate is closed the turbo works if its open all the boost generated goes down the exhaust

did you

Find the hose and elbow I described and is it on... ?
The turbo is actuated by rerouted exhaust gasses. The pipe I indicated for you operates 'vanes' that direct the gasses onto the turbine of the turbo and therefore operate it. I really suggest looking for that and making sure its connected. Its often the easiest things first.

Do you mean the very thin pipe under the turbo that goes to what I think may be something to do with the vacuum like a little flying saucer shape? If so I did look and it is connected.

When driving the car there is what I thought sounded like a blowing from the exhaust behind the pedals, could it be something down there?

So with my symptoms do you agree it is not electrical and the turbo is not gone?

Is the turbo meant to run when idling?

Is it safe to take the pipe off the turbo to see if it's running?

Should there be a vacuum from the thin pipe with the elbow or where it pushes on when idling?

Does anyone know how I can check for vacuum?

How I can check if turbo is working?

Where is the turbo solenoid on the 1.6 hdi 110?

Plugged in my code reader and no fault codes came up.

So the solenoid/solenoids are controlled by the vacuum and not electrically.

Where are they located on the 1.6 hdi?

So they are electrical, therefor they can't be faulty as they are not showing up on diagnostic and there's no engine management light on?

I'm banging my head against a brick wall at the mo.

Dropped the catalytic converter off today and no different so can eliminate that.

I've taken some pipes off the engine and have not yet found anything obvious.

Need to know where the turbo solenoids are and where to check if there's a vacuum.

Can anyone please help???????
