HDI diesel additive

Just in case anyone wants to try refilling their diesel additive tank on
models with the particle filter, you might be interested in part numbers.
For early models pre vin 9491, using the Eolys DPX42 fluid, the
Peugeot/Citroen part number for the 4.5 litre top up kit is 9979.95. Now the
painful bit - cost today from local Citroen dealer, £91.17
The later models use Eolys 176, and I believe the part no for that is
9736.86 for 3 litres.

 

Hello all

I've bought a top up kit from a Peugeot dealer. I consists of a 3
litre bottle of the fluid, an empty 1 litre bottle, a tube and a tap.
Unfortunately there are no instructions. Can anyone please enlighten
me how to use it?

Thanks

Richard

 

well u pee in the 1lt bottle mix it with the 3lts fluid stick the tube
on the tap and there you have it, all ready to use lol lol.have fun

 

Find the small tank in front of the back left hand side wheel (307hdi 2004).
Unhook the obvious filler pipe from the tank. Take your 3 litres and pour
some of it into the 1 litre bottle. Attach the rest of the filler kit
including the pipe and the on/off valve to the top of the bottle and then
attach one end of the pipe to the tank under the wheel. Turn the 1 litre
bottle over and squeeze gently untill all the fluid is out. Refill and
continue, it will all go in because the tank will hold 5 litres. After you
have done that you still might need to get the ecu reset because the 'Diesel
additive minimum' error will still keep appearing.

 

More woes, I'm afraid.

I managed to get the EOLYS tank filled and took the car to the local
Peugeot dealer to have the additive ECU reset.

They reset the particulate additive counters to zero and reported a
permanent fault showing the fuel cap missing. I returned the car the
following week for them to replace a faulty fuel cap sensor. Now they
are telling me that the ECU is saying that the EOLYS tank is again
empty and they can't clear the fault, a bit hard to believe if they
managed to reset the counters last week. They're suggesting that the
additive ECU may be broken. Is that likely?

Is resetting the additive counters the same thing as clearing the
"additive tank empty" fault? If so it's hard to believe that they did
it first time and can't do it again.

This little episode has already cost £260 (without the cost of the
EOLYS) and I'm worried that they are just going to throw bits at the
problem until its fixed.

Any advice (apart from throwing the car away) will be much
appreciated.

 

Another Peugeot dealer? If you tell us where you are someone may be able to
point you towards one. Contrary to what some people want you to believe
there are some good ones out there, it's just that you don't hear so much
about them.

What started as a "two hour job" has now spilled over into its third
day.

Given the legendary unreliability of these cars and that the diesel
additive tank always has to be refilled at some stage they must have
encountered this job before, so why are they making such a meal of it?

Before I had a mechanic friend of mine refill the additive tank I got
quotes for the job from two Peugeot dealers close to me (near Kings
Langley in Hertfordshire). One was £180 and the other one £280. Such a
big difference for the same job!

I can't help feeling that if they don't get the job they'll get you
another way.

You cynic

The fact that you had a mate do the Eolys refill and then took the vehicle to
them just to get the ECU counter reset was an open invitation to string you
along so they could get the same amount as if they had done the complete job.

 

A cynic??? Me??

I think I must have been wearing my donkey ears when I first took the
car in.

 

'cos we have the same problem now with our C8: has done 136000 km an
gave signal that additive level was low. Took it to Citroen garage
they refilled with Eloys (4l), cannot tell me whether the
regenerated filter (!?), charged me a lot of money but now the sig
"additive tank empty/low" doesn't go away. They say it'
the sensor (I assume the ECU??) but I'm hesitant about letting the
replace it without further questions or knowledge...charged for it..) so that's not problem. Oh yes, and the car smell
bad... like a bus

Here's what happened.

I filled the EOLYS tank and had to take it to a Peugeot dealer to have
the additive ECU reset. The told me it needed a fuel cap sensor.
Having read the Honest John forum (well worth a look) the sensor often
fails, so I could believe that.

I returned the car a week later for the fuel cap sensor replacement.
The "two hour job" they quoted turned into a three day job!.The
service manager started to talk about a new additive ECU and even a
new FAP and differential pressure sensor. I must have appeared to know
what I was talking about because he backed off and they just did the
fuel cap sensor.

A bit more rooting around on Honest John and I found out that the
additive ECU can be difficult to reset and rather than them spending
many hours trying they prefer to fit a new one and pass the cost on to
the customer. They often try and persuade the customer to let them fit
a FAP and differential pressure sensor just for good measure. The
whole lot can cost about £1000. They charged me about £200 which isn't
bad, given that Peugeot charge about £90 per hour for labour. From the
time it took them to do the job, my guess is that they really did have
grief with the ECU but didn't feel justified charging me for the time
spent. It just didn't need the other bits.

My advise is to argue that it's extremely unlikely that all four
components (the fuel cap sensor, the ECU, the FAP and the differential
pressure sensor) would all fail together. That way you might avoid a
huge bill.

Hope that helps

do: go back to that garage or get second opinion somewhere else.
think I'm going to ask for a fixed quote for price of replacin
sensor with garantee that if still not fixed they solve problem at n
extra expense....broken? 'cos we have the same problem now with our C8: has don
