Hpi Antipollution Fault

[Guest spritemajor]

Hi could anybody tell me if this sounds right i have got a 51 plate c5 2.0 HPI with a antipollution fault that has been diagnoised at Citroen main dealer as Fuel Pressure Regultor and Fuel Pressure Sensor but they say it might be the Injector pump thats faulty and causing the regulator to fail maybe with swarf at worst the bill will be £884 for all 3 or if its just the first 2 it will be £291 any advice you can give me will be great thanks

seems there was a recall on the fuel system so you might be able to have it done free,

HI Techbod my car is a HPI petrol not Diesel ;)

[techbod]

it could still be a software issue so worth checking with the dealers appols about my other post I was thinking HDI ;)

on another thread it says some time it can just be that the EGR return pipe is clogged or block

but i dont know where or what the egr return pipe does

hi, i have just purchased a c5 hpi that was diagnosed with exactly the same by citroen. too be honest i would not trust them with this engine as they do not have a clue! they will not admit to it but they will diagnose different things untill they get it right. i would advise to purchase a code reader from your local bullseye for £90 and read the codes yourself. you will find that your egv is stuck or malfunctioning. you can remove your egv from the block and spray it with wd40 and clean the carbon from the shaft and see if this works. citroen advised me a new pump was needed and it would be around £600 +fitting. so me being me thought i would burn the car before i paid that. i purchased a code reader from bullseye and it read it straight away and turned out to be a faulty egr which i located 1 from a scrapyard for £25, and a faulty lambda sensor, which thanks to TECHBOD i understood the code and repaired my car. all for less than £150 and i also have a codereader for which i can read all of my friends and families cars for free rather than them getting stung by the dealers also. Whatever you do dont take it to citroen as they will not admit this is a disaster of an engine. however all being said when it runs right is a lovely car and a pleasure to drive.

U should notice a difference around 2500rpm as this is when the egr valve starts to open up. it is closed on tick over.
