Hi I have a 2014 XC60 2ltr for a while at startup it has been running lumpy until it warms up. Since I had the EGR and cooler replaced I have been using Redex with every tank of diesel, so I’m puzzled by this fault.
I have had the car at my local Volvo garage and asked them to check it out but they found nothing wrong but I did tell them it was only when the engine was cold
