Eyols tank fitting damaged

Post by Phillipe »

After fueling up today, a couple of miles up the road the van displayed an amber warning light with an engine fault message. The only obvious thing i could find was a module/valve/part hanging by 2 hoses, which was rubbing the road surface. It appears this is normally clipped to the side of the eyols tank (left side of van, mid poin and has become detached and subsequently dameged.

The question is.. what is that part and can i get one or do i need to splash out on a whole new tank with the part included?

Any advice would be greatly appreciated !

It's your additive tank for the Eolys liquid used for assisted regeneration of the diesel particulate filter.

If it is damaged, then it will need replacing. The warning may be related to the engine ECU picking up an issue with the tank pump not dosing the additive to the fuel tank when you add fuel.

Thanks Mark, I'm trying to source the part itself instead of the whole tank.

The additive tank includes the pump internally, there are no separate parts. Of course this is separate to the fuel tank itself in case that’s what you meant.

Sourced and replaced the damaged Eolys "pipe fitting" and attempted to have the amber warning triangle ⚠️ light and limp mode reset with a "snapon ultra" obd2 tool, wouldn't do much more than read and erase fault codes.

'1442H/5186 unknown code' was one of those displayed.

Van still in limp mode wont rev past 3000 and is operating at reduced power. Warning ⚠️ still on.(with engine repair message) it runs well... within those parameters.

Have it booked in at a more specialised garage in a week, I'll update if i find anymore detail.

Anyone know of an obd2 tool/code reader that can reset the main warning ⚠️ light?

Marc, as you mentioned previously, im veering towards Eolys pump failure now if im honest. Probably should of replaced the whole unit however, due process; very few free lessons in life !

You can't reset the warning if the fault exists - that's as it should be, because as long as the fault is being triggered because of the problem, then the warning will come on.

It's looks like the pump assembly has been damaged when it came away and was flaying across the ground, so likely that if the wiring connections have not been damaged fromt he pump assembly back to the loom, then the tank and internal components are likely damaged.
