How often do you need to top up EOLYS PAT fluid? Diesel additive tank refill for DPF

diesel additive tank for Peugeot, Citroen, Ford. Volvo, and others

brilliant !!

[@mwahid2952]

2017 boxer, filled mine up as was close to empty. Never touched the software. So good so far…thank to your videos.

[@ryanh3285]

Mine was about 80000 miles and again with that fluid the price has at least doubled if not trebled over the last few years some garages didn't know what i was talking about and kept saying ad blue so i did it myself.

[@ChrisKHa715]

Citroen C 4 1.6 --> Eolys is still around 380 ml after 100000miles, dpf at 85% full of sud. Drive max at 2.400 rpm, use good diesel and oil, give the dpf chance to regenerate at the motorway

[@jage6126]

The limit is around 30L when it stops increasing the amount of eolys injected (for PSA cars). Fill up more than that each time.

[@canonball1914]

Think a vid on what the Pat fluid is would go down well, i have never heard of it?

[@malcolm6951]

Curious as to why manufacturers don't put gauges on EOLYS or ADBLUE tanks like you have on the fuel tank? Why no easy way to top up the EOLYS?

[@MrByootox]

They do on the Ad-blu tanks but you need a tool to get a reading on them. Not on the Eolys though.

[@careyautorepairs]

Thank you for the advice.

[@ORileysAutos]

No worries!

[@grahammaddison7482]

Hi can you tell me what gearbox oil goes in partner 1.6hdi 2012 thanks 🙏

[@woody2run]

So basically the system is overdosing if you fill up frequently on low miles. Or does the overdosing help to keep the dpf clear, in a car that will be suspectable to blocking the dpf by not doing many miles?

[@vaoamerda]

Wich error code this citroen show when the pats is low?

[@dizzyy1234]

What software is that? For resetting

[@nunomoreira461]

Ould help me, I need reset the eolys additive level on my DS3, however I don't have any professional diagnostics tool, I just bought the lunch crx129x but I'm not sure if will allow me do the reset What machine will do this for me not costing my eyes 😂

[@2010wembley]

What year was this introduced? I have a 2012 peugeot Expert. Its never been done and is on 104k. I know its not a dual mass flywheel so do i have a dpf and eolys system? Can you tell without climbing underneath?

[@ORileysAutos]

It will have one

[@RikAindow]

What happens if you take the magnet off the fuel flap door and leave it in place on the sensor? That would stop the system from using any fluid but i guess it would eventually throw an error or potentially upset the DPF.

[@MrByootox]

It won't dose the fuel tank with any Eolys fluid at all then I'm afraid.

[@fanfeck2844]

I take it the car isn’t smart enough to know how much fuel you’ve put in, and dose accordingly?

[@ClassicTrialsChannel]

that would mean a lot more complicated system

[@jonnoMoto]

It's braindead. You can tell the computer the tank's been refilled and it'll happily keep pumping nothing...until the pump dies.

[@user-gd6nc4pr6o]

Jimmy you have been reported to the authorities ..............for starting late today 😂
