Additive counter reset issue

[lionyo]

Posted this on behalf of friend...

Basically he has a 2002 406 2.2 HDI and the 'min additive' light came on now I had this problem a few months ago and managed to get it fixed by topping up the additive, getting it reseting by my mechanic.

When I heard that he had the 'min additive' light then I told him to take it to the same garage I took it to he got the additive refilled and reset the counters but the message still returns he has tried it on two different occasions but has failed.

We are now thinking that one of the additive sensors is at fault but before we go and splash the cash are we right in thinking this? Anybody what sensor it could be? Fuel level sensor? Or sensor that calculates the additive?

Your inputs are appreciated?

assuming your 2002 406 is similar to later 407's 307's etc theres a couple of places in peugeot planet that the car needs telling that the additive has been refilled.Not 100% certain myself but if you join http://www.peugeotforums.com theres loads on there with planet that can/will help you

Iwouid just have it De-leted totaly,

It has two counters in the additive ecu which need to be reset, also has a thermistor sensor in the additive tank which detects a temperature change when it is no longer immersed in Eolys.

The reset procedure is painful, time-consuming and goes something like this:

Refill additive tank, reset counter 1, reset counter 2. Stop engine, add at least 15 litres fuel, restart and repeat the counter reset procedure. I think it then has to do one successful DPF regeneration cycle, before the job's truly done. It also won't play if the DPF is loaded to a different degree of contamination to that it expects, (which I reckon is why most Pug dealers tell you to change it while you're topping the tank up).

All in all its a prize PITA. Why not just out it? - Much cheaper and easier in the long run.

Tried the above procedure but still didn't work

defap it... easy, cheap and 40 hp free.

I don't want to remap the car etc...

I think one of the additive sensor is at fault. Really frustrated.

Why not? you can keep the standard 98kW map

It will probably cost a few hundred to defap/remap and the 'min level gasoline' light may not go off.

So I'd rather do the job properley!

It seems you have not read the threads on the matter. It'll cost you about 20£. The ECU will forget everything about the FAP and the problem will never appear again.

£20 sounds reasonable! Who can carry this out for me? And will the dreaded 'min level gasoline additive' message go away and the orange particulate filter light on the dash go away?

Yes, the ECU will completely forget about the FAP, no errors, no lights. In this forum you can find an How-to section with a guide on how to do it, it's pretty simple. However, if you do not want to do it yourself, you could ask a mechanic to, showing him the guide, or, better, join on the coupé forum (http://www.406coupeclub.org/) and ask for someone to help you out. Also on this forum there are some that could help you. Sadly I do not know UK geography well, but Doggy, Finchy and Parm for example are experts in the field, I do not know if they are far from you. On the coupé forum you'll find more people able to do it probably.
