i am also facing this exact same problem.
at first service center diagnose and tell me to change the dump valve. but after changing the dump valve , depollution comes again.
now service center determine that my depollution error is caused by high pressure fuel pump.

i am trying to find this part on ebay, but cannot seem to find it. should i try to find this part from a chop shop?
or should i turn to aftermarket, for example walbro 255 in-tank fuel pump ?
as i feel that paying 2k+ is a bit much.

or can anyone recommend independent workshop around klang valley which specialize in peugeot ?

i have attached pictures of the diagnosis report.

You can try to pm chargerguy. He's got a mechanic friend who can service Pug cars. He also got lubang for cheaper spare parts I think.

just to update, see if anyone can give me some advice.
recently my car got depollution fault, car can still move but reduced power.
service center report diagnose got 3 faults -
1. dump valve
2. lean at full boost
3. rich at idle.
i swapped my dump valve with my friend's car, but the fault still appears.
it idles roughly.
service center looked at the report and says if its not dump valve problem, then it will be high pressure pump.
but i dont think its fuel pump because , if i clear the fault, my car can still have power for 1 or 2 days until the fault reappears.
also i have already done top overhaul to clean the carbon.
what do u think the issue could be? do u think it could be lambda sensor ?

From your diagnostic, lean/rich A/F mixture is due to wrong metering of either air or fuel. So for fuel is HP fuel pump and air is MAP sensor. Not forgetting the air temp sensor.

As you have rightly said, the lambda (or O2) sensor is another possibility as this sensor trims (small adjustment) the amount of fuel to get the ideal A/F ratio.

Perhaps, you can take a closer look at the MAP sensor?

Hi all sifus,

I received a bad news last week, i have the engine fault warning + depolution sensor warning, after sending to SC for checking, they told me i need to replace the high pressure pump which cost RM 2.5k sad.gifsad.gifsad.gif (my car already out of waranty)

Would like to seek some inputs from you guys if this is a known issue? and i should proceed with the change? As this is not cheap. Previously i have depolution sensor issue and they just change solenoid valve. I just worry they keep changing parts and waste my money.

thanks!


Hi,

I'm having the same issue. Where did u get it repaired and how much?

Most IMPORTANT beside checking those sensors and parts do ask them to check those hoses and seal connections. They are number 1 culprits in most cases! biggrin.gif
