Did the tech check compression? I’ve read about exhaust valves burning/cracking on the SPA’s. Old reliable will be here soon to insist Volvo’s are a reliability leader and your case is truly an anomaly.

 

Volvo is a very strong dependability leader. That is true. The data shows Volvo is the lowest cost to own premium car believe it or not beating out even Lexus. Volvo is a forced to be reckoned with in the dependability game.

Most likely it's a fuel injector. Swap the #3 injector to another cylinder and see if the misfire follows. Have you ever run BG 44k through the injectors to keep them clean?

Burnt valves are usually caused by low octane fuel. Are you using premium fuel only?

 

Interesting. I usually use either 91 (premium) or 89 (mid)

 

Warning: If it is an injector then stop driving the vehicle immediately until you replace it. If it sticks open for too long and gets to an extreme with out being addressed, you could wash a cylinder. If this is the problem, replace all the injectors out of precaution and not just the one.

Keep us updated.

 

All that reliability and technology and misfire is the only code you get? Could be so many reasons. Tell you mechanic to open the book and start testing all possible causes, strarting with the cheapest. No new parts until the diagnose is 100%

 

You can easily monitor the misfires in real time on a smartphone, with a obd2 bluetooth dongle:

Check compression but most likly fuel injector..

 

If the injectors haven't been serviced, 90k is not unreasonable for a failure on a Volvo. Not sure why, but these cars do seem to need injectors at earlier intervals than others. Mine quite dramatically requested new injectors at 122k by dying on the highway. It's fixed now, but it's something I didn't want to worry about again, so I had all of mine replaced.

 

The DI engines seem to wear through them faster. They aren’t typical injectors with those. They are a much higher pressure. I believe that has something to do with it. I have seen port injected cars run into it too though, just not as much.

 

No reach condition code?
How are the fuel trims?
I get like 20 codes each time and nothing is wrong....
There has to be another code, you need to go to volvo workshop and read the codes.

 

Don't put to much attention on specific topics here. People speak of their experience, while this is your car and there might be another issue.
I'm sure there must be another code, besides misfire...

 

I don't understand, low compression on cylinder 1 but misfire on cylinder 3? Maybe you need a new mechanic.

 

Run away from this brand and never look back. Lexus if you want to avoid this kind of problems.

 

No that's not true. Lexus has had their share of problems too. Volvo is a car people buy to avoid problems. This sounds like it could be a fuel issue. Volvo is one of the most dependable vehicles of all time.

 

compression test fail is fuel issue?
lol
maybe there was or is just to much heat. I wouldn't know.
At 89k, this is a funeral for reliability score.

 

Yes if it burns a valve that will cause issues.

 

funeral.

 

That's not unique to Volvo. If you do that on any car you can expect issues. Unfortunately not a lot of people know about that.

 

89k. funeral.
With worst fuel in asia, toyota would survive

 

If you had some sort of lower powered Volvo they would be able to run on lower octane fuel too. If you have a higher performance Lexus/Toyota that needs premium fuel and you put regular or mid grade in it you can also run into issues like this as well. So it all depends on the state of tune of the engine.
