1.6THP 156 engine stutters now and then

[victoryo]

Hi all,

First of all I am new here and came from the 208owners forum but thought it would be a good idea to post the question here aswell
as the DS3 has the same engine.

So the problem is I have a Peugeot 208 2013 with a 1.6THP 156 version with 31.000KM at the moment.

The problems with the car started with some rattling noise which was very annoying. So after a few garage visits
they finally found the problem and replaced the whole turbo under warranty.

So the rattling problem is sorted. But what I also notice now is some engine stuttering when going full power!

The things I already tried and changed are:

* New NGK Bougies.
* Engine flush and new oil filters + 0W30 oil
* Pipercross panel filter
* Forge BOV to replace stock valve

I bought the car with 26000KM so I don't really know how the previous owner drove it.

Do you notice the revs dropping considerably when slowing down from high speed? My previous car (although a Ford) had a split in an air hose which caused some lumpy driving and stuttering/cutouts when braking because of lack of air flow to the engine. Did you see anything abnormal when replacing the air filter?

If it's not that then there's lots of technical geniuses on here who should be along shortly with better suggestions lol

Get your car into the dealer and make sure you have the latest sw update. The latest update for DS3 with 5FV engine is a massive improvement for smoother running. If this is already done then you may have another problem.

Clogged inlet valves?? By the sound of it and your ammouny of mileage, this could be your problem.

Thanks for the answers.
Clogged inlet valves, I don't know. Can't check it myself.

And about the software update. I have a Peugeot 208 and I am not sure if there is also a software update for it
with massive improvements....

So, I've been to the Peugeot dealer to check what the stutter could be.
They have read it out with the computer
and came to the conclusion that the High Pressure Pump got errors and needs to be replaced.

With High Pressure Pump I think they mean HPFP??
And if this is true, can this cause stutters indeed?

They will be referring to the HPFP as you suggested. Common fault.

Ive not heard of a faulty HPFP causing the stutter you describe, it will create error codes and maybe a limp mode and definitely uneven idling but ive not heard of stutters (without the previous indicators).
i suspect you have heavily carbonated valves which 100% cause stutters under hard acceleration or load.

Hmmm.. so probably after replacing the HPFP under warranty I will be back soon with same problem .

Although the Dealer doesnt have time to replace it yet so I have to wait for a month.
Is it bad for the car to drive a month longer with a not fully correct working HPFP?

Can it do more damage to the car?

Also it is not really stuttering. Its more like a sort of vibration going on while accelarating. Also going uphill will increase the vibration haha.
But after reading a little more about the HPFP on the net I might also found the cause of the car shaking when running IDLE.

Mine was a 'burbling' and lumpy idle plus the car went into limp mode throwing up an error code stating fuel pressure outside tolerances (or along those lines). mine was an original 2010 HPFP so Jamie from Sp Tuning changed it (along with his own) to the latest spec model. this cured those issues.

[victoryo]

Hmm oké. Well I have to wait a month before repair so we will see if it will help then

One question is, is it bad for the car to drive around with a faulty HPFP? Can it do more damage to the car for example?
Else I will drive it as less as possible.

Your ecu should shut down the power if you lean out the mixture too much so in theory it should be safe....

Oké! Thanks! That's why I always had the feeling my old Peugeot 207 1.6 THP 150 which is 200KG heavier was faster then my new 208, haha.

Yesterday got my car back from the garage with new HPFP.
And I can really feel the difference.

Car accelerates much smoother and faster now!
Although I can still feel a little stutter/vibration in high gear when give full throtle.

But I think this has to do with carbonized valves so won't go back to the garage for that I guess.

In octobre I have an appointment for a wallnut blast so untill then I can live with that and hopefully after that
the car will be complete stutter/vibration free
