2010 XC90 random stuttering

[davie4]

Hi all

Looking for some help on this one. My 10' 2.5 AWD XC90 has recently started stuttering sporadically and losing power.

To give you some backstory. Recently had the full clutch replaced and all brakes and discs too. Drove to Hull and back from Newcastle a week or so ago and it was fine though the Monday after I started seeing this issue.

The "Engine Service Required" light appeared and the car seemed to be driving ok then suddenly stutter as if the engine was struggling for a period then seemingly put itself in limp mode. This would only happen now and again, got example I drive 7 miles to work with no issues then it appears again on the journey home.

There is also a strange metallic noise that occurs when accelerating or when you take the foot of the gas. Like something whirring but slowing down. Hard to diagnose as it also sounds like something stuttering. I think its coming from the right hand side of the engine (as you look at it face on)

Thought it may be the cheap supermarket fuel dragging some crap through it so put some fuel additive in last week to flush it out and whilst there was some improvement it still keeps popping up again.

Any help is welcome. Already sank a load of money into the car for repairs over the last few months so could do without another big bill!
