After further check with garage and volvo dealer, they both confirmed my car has pat fluid, which is Eloys.
From the attached pic, it looks like brown liquid with a minor leak around pump. My local garage checked diagnostics and they reported DPF additive pump error and can’t operate/ get further info like additive level from pump.
There is suspicion that I need new Additive tank and/or pump, but not sure. Can anyone advise any further, before I spend another £300-500. Thanks
Additive tank was filled March2020 with regen and since then did only about 300miles after which and car was sitting on my driveway for 10months with dead battery. After latest service I did 900mile motorway miles and had 68-70mpg. So not perfectly sure if I had any problem despite this small additive leak.
