hi people,

im going through a nightmare at the minute. Halfords messed my car up by mistakingly replacing a fuel pump which didnt need changing (it had dpf issues) and replacing it with the wrong fuel pump part- so the car doesnt even work now. I've now taken the car to a specialist, who strongly suspects they've also 'mistakenly' put elosys DPF fluid into the actual Fuel tank. The peugeot specialist has a sample of the fuel he drained from my tank and thinks it could be dpf fluid, as its red in colour. I was wondering if there anywhere i could send this sample, a) so i can have proof to show to halfords they have put something dodgy in with my fuel, and b) to confirm exactly what it is

halfords deny ever putting anything in there, but i know they must have because it wasnt me and it wasnt the peugeot specialist. the had the car for four weeks and were mucking about with it....

any help much appreciated,

thanks

I've never been 100% sure on this one, so you'll need clarification from one of the experts, but a small amount of additive does actually get injected into the fuel tank/system every time you fill up. I have heard there can be an issue with the DPF system that will actually dump the whole lot of fluid into the fuel in one go - this could be what happened hence a large quantity in the fuel at the moment.

Anyone who can confirm or correct this...

Can 100% confirm that the additive is 'dumped' into the diesel tank, whether there are faults where it does too much I don't know.

Joey , thinking outside the box here but could the contamination not be the initial cause of the failure??

Should contamination have been present in the first instance then the pump may well have required being replaced however with the fuel tank still full of contaminant it would also kill the new pump.

Just a though.

My son, the mad scientist, MSc Cambridge Chemistry, says that it is unlikely that Cerium compounds (eolys fluid) would do any damage to the fuel lines, pump or injectors. During combustion, Cerium Oxide is produced and would then pass out of the exhaust.

as long as you have a dealer technician report saying they have fitted the wrong part thats enough evidence to say they fooked it...tried and tested when i had an issue with a misfitted timing belt

I appeared in court representing Groupama insurance compant Ltd against a plant hire boss that had been using contaminated diesel out of plant containers and it killed his pump , injectors and fuel lines etc £4700 inc vat

I had the Honda dealer report , my report and the report from a lab regarding what was in there , water amongst other things.

No damage existed to his fuel flap lock so it must have willingly been put in there so Groupama kicked the claim out.

He took the matter to court and won as it could not be proved who or when had put the contaminated diesel in the tank.

Cost a lot of money , hence me asking if the contaminant may have been part of the original fault??

hi jmkent and others, really appreciate your responses....

so, does this mean that

a) its highly likely the reason why my fuel is red is because dpf fluid has been 'dumped' into my fuel tank (not by halfords..)...but by the car itself...(could someone explain why/how this happens- afo/ jmkent) and how do i stop it over-supplying...?

b) it shouldnt be too much of a problem even if it is getting in there, as it isnt damaging to injectors etc...

Halfords have now accepted that they put the wrong fuel pump part in (still doesnt change the fact that i still dont have a car now, for 7 weeks!)

and they are willing to pay for my specialist to refit the proper part, however they won't pay for anything to do with the contaminated diesel and the effects it may have on the fuel system....

but if what PureJoe's scientist son is anything to go by, my injectors etc. should be ok.....fingers crossed......just need to get that new pump in there!!


thanks everyone for your comments, i dont know why but ive stopped getting email notifications of your responses so thought no one had responded!!

I was told by a specialist that a problem in the system could mean that the entire lot would be injected into the tank - unfortunately I don't know where the problem lies and hence don't know how to cure it.

My strong opinion, based on a couple of years of problems with the DPF system as a whole, would be to disable it altogether. That way you don't have to worry about it at all and can be happy that you won't have to do any more maintenance on it in the future - I really can't see the downside of removing it.

As mentioned by PureJoe, it's not going to do any damage, but I guess one simple way to keep the concentration as low as possible would be to keep topping up the diesel (to full) for a while...or even better drain some of it and dilute it more, then add in what you've drained the next time you have an empty tank, if that makes sense! That's probably way OTT though :rolleyes:

problems using Redex with 307 hdi- dpf issues....

hi everyone,

i think my current problem (white smoke from exhaust), engine cutting out, could be connected to the fact that Halfords may have used Redex in my 307 hdi 1.6..

Now i have read on various sites that peugeots, particularly ones with a DPF, are incompatible with Redex diesel,

anyone have any experience using redex in their hdi? would this require a replacement of the whole fuel system if incorrectly used?

thanks

Ah your way ahead of me! White smoke can also be turbo. Performance ok? How long as it been doing this?

its a very complicated situation. its a 2006 1.6 hdi. the cars not running at all. heres a summary;

broke down 2 months ago with 'low oil pressure', aa took it to halfords, halfords mis-diagnosed the problem and changed fuel pump with a different (wrong) fuel pump part, complete diesel leak for obvious reasons, they then changed dpf filter, car still wouldn't even idle, returned the car to me, car is in a mess, white smoke from exhaust, engine cuts out after 2 seconds- 5 major faults on diagnostic. took it to a specialist and he realised straight away its wrong fuel pump.

the specialist is wondering why the remaining 2 litres of fuel he drained from the tank was red....he thinks they put eloys fluid in fuel tank by mistake, halfords deny this, but i thought it could also be redex......which is meant to be bad for peugeots.....but they havnt owned up to doing that either...

thanks

thanks afo, i would really like to disable the whole dpf unit as you say,

however, i thought in order to do the removal you have to have the car running without any faults...in order to read ecu through galetto etc....

but the car is plagued at the moment, even though the dpf is one of major issues, removing it might actually help sort it out.......is it ok to disable it all and do the remap if the car has other faults...

Ah yes! I've been following your other thread. Are you sure it's not just red diesel? (Agricultural stuff) HDI's do not like it at all.

I ve used redex in all my hdi pug's with no issue but only on every 3rd or 4th tank. As per last post I would think red diesel has been put in the tank but would question that as how would halfords have red diesel as its for none road use.

so just to confirm, red diesel, if someone/anyone ( i havn't...and i cant see how/why halfords would have- and it was a fleet vehicle before).....but if it was red diesel that would be bad for the fuel system/engine?

it could also either be redex, and or eloys fluid.......no idea....


thanks
