Customer Question

We have a Volvo S80 d5 diesel 2.4 litre with 100,000 miles ( 160,000 Kim)
Always serviced and runs fine but idles rough recently. All filters changed.
First step was to put injection cleaner via tank 3x
Have just completed a 600 mile trip still idling rough.
Before pulling out cleaning/ testing injectors anything else that could be causing rough idle( all vacuum lines and engine mounts have been checked.)

Hi my name is ***** ***** am here to assist you.

it sounds like you have covered most items to check, the only other thing to check is the egr valve.

have you had the codes read ??

if all that done then injectors are next as you say.
