Do the dpfs with eloys fluid regenerate every time on a long run if the exhaust gets hot enough or does it only do it now and again,

Cheers chaps

They only regenerate when needed.


There are sensors in the exhaust to detect when it needs doing.

Mr Singh

EOYLS are injected in to the combustion chamber with diesel to raise the exhaust temp cos the smaller engines have difficulty getting to the required temperature to regen the DPF as what i was told by the master tech at volvo.

on later cars the engine mapping was changed for the removal of EOYLS.


as alex said the car will regen as and when it requires depending on exhaust pressure readings the ECU gets.

Ahhh cool thanks took it on a long run today to clear it but not sure if it did or not lol I thought it did it when the exhaust got hot enough threw motorway driving, thanks for reply
