Why do you beleive there is a fault in the wiring?

2000 Volvo S80 | Answered on Jan 29, 2019

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.

You may have noticed increased fuel consumption, loss of power and general 'lazyness'.

Better to take it to authorized Volvo service for a checkup/fix.

Is there any problems with the car?
I'm assuming you mean the service engine soon light.
take it down to a local shop, and get them to put a scanner on it.
It'll show why the light is coming on, and from there you can decide what you need to do to fix the problem.

Hope this helps :)

its not reading earth the throttle position or the abs. or can even be the engine revs. low voltage can be a problem that causes this. a bad connection or even a faulty alternator. turn off then back on again is resetting the power and the longer on the weaker it goes to. like a bad regulator.

To repair your cluster you can google a company called XeMoDex, or you can find a *same year* S80 in the junk yard and take the cluster from that and hope it's ok.

The thing is that the car will generally show whatever the highest mileage is - whether it's in your car's computer or in the new cluster. If your car has 100K miles and the junk yard cluster has 150K miles, it will show 150K miles.

Awesome! So do you have a particular question about your vehicle?

2000 Volvo S80 | Answered on Jan 22, 2018

Ken check fuses ..Is this one that you can open the boot from inside the car ?Try and hold the boot kid down while you set the alarm it might lock it

2000 Volvo S80 | Answered on Nov 16, 2017

Is this a lever or button you pull or push? If it's a button than it must be electric and there is likely a fuse somewehre in the link for both trunk and gas lid that may be under the dash, by the engine, or somwhere else.

If it's a lever than it's likely a cable that runs back to them...but not sure how BOTH would be 'broken'. Does the lever feel 'different' as in loose or less tension than in the past?

Hi,regarding your Volvo s80, have you noticed recently in the past that it almost did not want to start and maybe sometimes it did start?
I am asking to see if you noticed this recently?
If you do not hear your car even click, when you turn the key,
Have you checked your battery,and the battery wires to make sure the battery is good?
Maybe the battery needs to be replaced or a wire is loose and there is no connection with the battery,and wires, please check your battery first.When was your battery last replaced? Check the battery cables to see if there is any
noticeable corrosion that you can see that might be interfering with the contact.(If you see green and or white powder try cleaning off this area with a battery terminal brush)
Remove the terminal wire clamps, most can be loosed and removed from the batteries positive and negative terminals with a flat head screwdriver.
Then clean the area with the battery terminal brush ,if it has the green/white corrosion,you will be able to see if it does.
Be safe and protect your eyes always with safety glasses.

I just went through this with my daughter's car.
The Volvo s80 also has what is called a flywheel. (Very expensive to buy new from the dealer, it will cost a few hundred dollars)
Tip, If it is the flywheel you can shop around for prices depending on your budget and preferences./(New or used)
Yes,you can replace the flywheel even with another used flywheel,just make sure the teeth are not damaged,or worn.
A used flywheel could save you money, which most likely will be needed to pay someone to replace and do the work,if it is the flywheel.

Replacing the flywheel entails taking apart the entire front end,
the entire suspension needs to come out if it is a front wheel drive,
the engine needs to be dropped,
and the transmission needs to be separated.

Second and very important tip make sure if you are replacing the flywheel that the new or used one is an exact match for the one that is in your car.
(It must have the same exact number of teeth.
(I learned this the hard way)
Some flywheels have 133 teeth and some maybe 142, so make sure it is an exact match.
You do not want to have your car taken apart,and put back together again and find out it is not starting after all this work because you bought the wrong flywheel.
If the flywheel in your car has 133 teeth then a flywheel that has 142 teeth will Not match and you don't want that to happen,because your car won't start after all that work and you have to do it all over again which will cost money.
The flywheel is a large almost 12 inches in height and 10 or so inches in width,heavy metal circular shaped piece that has grooves(or teeth that go all around the metal,if any of these teeth are worn down what happens is when you try to start the car it will turnover but the car won't start.
The reason is the flywheel rotates to catch on the grooves and sometimes over years there could be an area were maybe even 2-3 of the grooves(teeth on the flywheel becomes worn.)
If the flywheel has damaged or worn teeth ,it won't be able to turn and catch,and the car won't start.
If you do not have someone to do this type of work,take it to a transmission shop and they replace flywheels

I hope maybe all you need is a new battery.
Keep in mind the flywheel ?

My daughter's car is a Volvo s80 2003.
I'm not sure how many miles are on your vehicle or if you just bought the vehicle,but over time If the teeth are damaged or a few,even 3 teeth in a row are worn down,this can happen and the car won't catch to start.

As I mentioned the cars flywheel turns and the teeth have to catch on the starter and the flywheel rests on the starter enabling the car to start once the teeth catch.

We also replaced the starter which went through a toll from her continuing to try to start the car.
If it is the flywheel it is always good to replace the starter also in th s80.

I hope this information is helpful to you.
If your wondering,we went with a used flywheel and new starter and now the car starts great.

You have a bad relay under the hood in that fuse box Regards Chris

That sounds like a thermostat. Usually not an expensive problem, but one you want to address soon. Right now, it's convinced that the engine is hot, and is wide open. It could easily flip to thinking that the engine is cold and stick closed. THEN your radiator WILL boil over.

You need to run an OBD2 fault code test, once you have the codes you can then begin diagnostics to repair this.
