This is a gearbox issue. Both codes relate to the transmission. Specifically P0717 is to do with an engine speed sensor that lets the gearbox know when it is supposed to change gear. Have you had any work done recently. They might have disturbed some wiring causing this problem. Replacing this sensor is not a simple task as i believe it is inside the box so requires the gearbox to be removed. There are some good Volvo forums on the internet that will be able to help you and point you to a local independent Volvo garage rather than a main dealer to keep costs down.

Borrow a code reader from an auto parts store (free) and see if any trouble codes show up (the device will have instructions and is easy to use). That should give you a clue to the problem. Problem could be sensors of some kind. If no codes, could be a clogged fuel filter -- when was it last changed?

On a web search I found several people that had similar weird dash lights/operation issues. Someone thought it might be a faulty ignition switch but that was not it. The success came as follows: "Alright fixed the problem it was an electrical relay. If you remove the cover of the fuse box under the hood there are 4 large relays. two of them are unmarked as to what they are for but I disconnected them while the car and everything was running and it turned out that one was for the lights and the other was for the interior electrical components A/C, Radio, wipers, etc. I replaced the one that I needed and all is well now. Thanks for the help $20 for a problem that had me ready to sell the car." Your issue may be similar .. a faulty relay in the fuse/relay box under the hood...which I think is just forward of the driver side wheel well. Usually there is a legion/map on the underside of the lid that tells you what each relay and fuse is. Good luck on your troubleshooting

Possible DTC in ABS module."

Output Speed Sensor No Signal http://www.autocodes.com/p0722_volvo.html

the fuel filter is it a inline type filter if so check the arrow on the filter make sure the fuel is flowing in the right direction because some of these filters have a non return valve in them.a garage made this mistake with my brothers car, hope this helps its worth checking. it sounds like a restriction of fuel

There isn't one.

Could be fuel line leak or evaporative.#455.

Possible cracked head or block

Check seatbelt wire connections and if it has one, the comfort control module, crash sensors and crash module. I’m happy to assist further over the phone at https://www.6ya.com/expert/howard_977676954994c5b2

I had a similar problem after having my oil changed at jiffy lube. The problem was that they hadn't fully tightened the oil filter, so it was leaking oil when the engine was running. They did it to me on two cars. I don't go there anymore. If you don't see smoke, you're not burning it. If you don't see it under where you park your car, it's not leaking when the car is parked.

done one not so long ago and i had to remove the front bumper and the safety thing behinf the bumper then pump the ac gas out to remove the ac rad then it was easy
