Hi guys
Just topped up my Eolys tank with Pat fluid, for anyone worried about doing it, (I was a little) Don't be, its so easy to do and only took me an hour and now I know how to, I could do it a lot faster
Can someone put my mind at rest, is pat fluid a brown rusty colour???????
Eolys?

Did you reset the computer via Lexia?

Re: Eolys?
The computer doesn't know the fluid level has been topped up so will bring up the "additive low" message prematurely because its using the last top up reset as the reference point.

Re: Eolys?
It depends what year your C5 is... I think, early C5 dont have a reset option and the ECU needs to be changed... but later C5's have the reset option.
The ECU* ... is in the Eoylys tank so the whole tank needs to be replaced if needed... which is silly...
I have in my mind...if the car runs out of Eolys or the DPF is blocked, I will totally remove the system.

Re: Eolys?
Pat fluid is indeed a dirty brown colour, if you don't reset the ecu you will get a message flashing up " diesel additive minimum level" especially after filling up with diesel I don't know if it continues to try and inject fluid or not? No doubt someone will advise us about that!
It doesn't throw any other faults or trigger limp mode at all. Early C5 MK1's need a new ecu after top up as you can not reprogram the early ones.If you try and reset it Lexia will explain in detail how to do it and then tell you you can't pmsl.

Re: Eolys?
Thanks for the replies guys
Its a 2002, and the reason I asked is that it threw up a anti-pollution warning and went into limp mode 100 miles from home a couple of days after putting the pat fluid in
What warning comes up if the DPF is blocked???

Re: Eolys?
My garage I use has been unable to reset the eolys or discover why it has gone into limp mode, he says there are loads of fault codes, I will post on here When I pick it up
