Check the codes, if there is a misfire it may tell you which cylinder(s) is misfiring. The coils fail, and make sure to use Volvo spark plugs!

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls. Then you can access the bolts that secure the mirror onto the door

Weell it sounds like you have the days old problem Pepole dont know how to look after there cars.
The muck you still have in the engine isent doing it any good and so you have to get rid of it all, as its in the engine block and is got to go ,,so drain a little of water out and put in 1/2 a cup of washing up liquid in the radiator and start the engine and let it get hot and take the reves up to 1000 rpm now and then to keep the water going around the system, after about 1/4 hr turn off,,stand for 10 minutes ,,and then remove the cap slowly and then take off the Bottom hose and let all water out also take off Top hose at the engine end and put the house water hose in the top and turn it on till all water comes out clean. Then put hose up into the bottom hose and do the same again ,and the same in top again.Now with a clean engine you can do the same to the new Radiator and wash out all gunk .then check the thermostat and make sure its 100% (any doubt through it out) and take note how it comes out so you can fit a new one the same way,
Now refit both hoses and fill with coolant or antifreeze and TURN on the heater to hot before starting as you also have to get out the air from heater when it was drained and you will trap the air which might cause you code problems..
But now try service light reset
1,,Turn Ignition to Number 1position.
2,,Press and hold "day counter"reset button and turn
ignition to II(second) position,hold down for about 12 seconds.
3,,Afterservice light flashes,release button,there should be 2 beeps confirming reset was successful.
Let me know how you get on .. Ron

On my 2002 S80 T6, the problem is the brake booster diaphragm position sensor's failure (Volvo 2002 S80 T6 part #31261486--other years, models might be different). This is essentially a piston-driven potentiometer that tells the cruise control system when you've applied the brakes, signaling it to switch off control of the throttle. It's mounted on the back of the brake booster with a wire circlip. It's not easy to get at, and I had to remove the cross-brace between the shock mounts to get at it more easily. The part's about $90 from online parts sources, more at the dealer, plus my dealer wanted a king's ransom to install, $400, parts and labor! While not easy to get to, it's fairly easy to replace--just BE SURE to pump the brakes a lot, engine off, before removing it so that residual booster vacuum won't **** the rubber o-ring around the sensor's cylindrical body into the booster chamber. Hardest, most aggravating part is removing and replacing that steel circlip that holds the sensor in place. Dropping that little steel band into the back of the engine bay kicks off a whole new adventure!

SOURCE: volvo s80 dashboard fault

This is a known problem although Volvo will not admit it. The dash needs to come out (10 min job) and sent away for a simple repair. Total cost is about £150 but you will need to get the SRS warning that will be showing in the LED message display cancelled by a Volvo dealer after the dash has come back. Don't try a scrapyard dashboard the ECUs have IP addresses. I used a company in Kent to do the repair. Get onto Google there may be a repairer more local.
