Hissing from engine when accelerating
Car: XC60 D4 2017.
Last week my car started making a hissing from the engine area when accelerating (only when warm). When I googled it, intercooler and turbo pipe/hose split came up. I looked all over but could not find anything. Weird thing is it now has stopped.
Heres my thoughts, any advise welcome.
Could it be my car regenerating the diesel particulate filter. I was towing a caravan when it started and it was under load.
