S40(2009 reg) DPF cleaning additive

[smartsarath2003]

Hi, I have a 2009 Reg S40 (2010 model D4 164T). When I has some dashboard messages appear, I had the car serviced by independent mechanic who said the dpf catalyst tank is empty, so he filled it up and did a forced regeneration and car was running normal. If I remember it right he told me he used Adblue to fill that tank.

I heard Adblue as well as other name Eolys. i previously thought, these two are same type and just different brands. But now I understand that they are not same and work differently. Can someone please confirm this?

After filling with suspected Adblue, I didn’t used the car that much and was sitting idle for almost an year. this week I did 900mile motorway miles. However, after one motorway journey, I observed reduced fuel efficiency towards end of the journey suddenly and even after reaching the traffic 20min later… stop-start didn’t work. With new battery, AC off, I am pretty sure the re-gen didn’t finished off. Should I get the car checked again and get right catalyst Eolys filled?

I also notice a small leak on drive way when parked from rear of the car, which is not fuel. Not sure this is related, but I attached the pic for comments.

Thanks
