C5 x7 2.0hdi 103kw,2011year stagger when hit the gas and strange noise

Post by Asske »

Hello dear friends,
I am owner of C5 x7 2011year,2.0hdi 103kw

I have several issues with my car.
First of all,it started to lag when i hit the gas pedal like for amilisecond it doesnt have power then immeadiately get the power.
I had it taken to the car shop where they connected it to the diagnostics and showed following errors
-p1351(connected with engine heaters)but he mecahnic said it is not so important for the issue
-p11aa was the second error whic is connected with the turbocharger(he told me it is vaccum valve on trubine)i changed it and doesnt have any more that error
But the staggering conntinued to happen,sometimes.To highlight,it doent happen all the time...it happen sometimes,maybe 10days wont happen and than out of blue it happens.
I had it taken to other mechanic,and he told me it could be fualty injectors of faulty turbo.
But nobody cant for sure tell what is it.
I will post also my youtube video with the strange noise coming from the hhod,which happens sometimes when i hit the gas pedal.

Hi
Thank you for posting this, I have the same issue with the same noise occasionally but have been unable to catch it on video.

It almost sounds like a 'rasping' noise, indicative of a turbo hose leak / split, more noticeable when giving the car some throttle.

Exactly.Hope it is not turbo itself.

Hi
No I haven't found out what causes it but I have worked out that if you put supermarket diesel in it is much more frequent.

Thanks for the reply Steve.
I will take my car for sure to the authorised Citroen service,as I cannot find the solution for the issue.

I wonder what would happen if you were to use some main distributer fuel (such as Esso or Shell) with some injector cleaner in the tank? I bought three bottles from ebay not so long back;

Hi
Thanks for answering.
For the fact I live in Bosnia I do not have possobility for Esso or Shell fuel.
I had already tried with injector cleaner,bit not the one you mentioned.I havent seen any difference in the car behaviour.

OK, so what I meant (by the fuel, that is) is to use some fuel from a main supplier as opposed to that from a supermarket. One of the reasons supermarket fuel is cheaper is that there are fewer 'useful' additives in it, and your car may be finding that to be a problem.

Good morning all
I too have tried injector cleaner to no avail, I find if you are gentle with the accelerator pedal through a certain rev range say between 1200 / 2000 rpm it is not as frequent / noticeable.
Like I said in an earlier post Morrisons fuel sometimes makes it worse but not every time you fill up which is strange unless they purchase from different suppliers.
I find Shell or BP seem to help but not cure the issue.
I sort of compare the issue to a type of pinking In older petrol engines (just my take on it)
I would appreciate an update if anyone manages to get to the cause of the issue..
Just as a footnote, I have no warning lights illuminated on the car.

Regards
Steve

Yes,I hear you.I am using only best possible fuel.

I was today at garage my friend told me about.
The mechanic said to me the problem is EGR( little bit clogged ) and need to replace washers on injectors.
So,my next step is to do that.

Hi
EGR may be the issue in regards to cleaning but I cannot see it being the copper washers at the base of the injectors as its not chuffing (blow back through copper seal) and no leak or smell of diesel.
But maybe the EGR does want cleaning

Thank you again

Steve
