Now that you mention it I think the fuel filter was changed when my mechanic changed the transmission oil, engine oil and a new air filter.

Just why woudn't it be detected on my mechanics diagnostic? Also after changing the pressure sensor and temperature sensor, the "Engine System Service Urgent" message no longer appears either.

Yea the fuel filter had been changed to a new one. Just checked.

Default New idea

So a friend of mine told me that someone else I know also had a similar problem with his volvo. On acceleration, there's a lack of power and black smoke.

His fault was the turbo. After getting a new one everything worked fine as it should.

Does anyone know if the turbo could be at fault here and how to diagnose it?

hi did your dpf get reset on the car ie like when you have a service.
I read some where that the dpf counters have to be reset back to zero.
I could be wrong but its worth a look .

No I have not had the possibility of reseting the computer as all garages/services are still shut/don't reply to my calls/voicemails.

But I'm still trying to get booked in. Non of my scanners work so I need to get a volvo one specifically so I can't do anything on my own.

white smoke/black smoke does sound like a fuel delivery issue. (I agree with maurice mynah) - I would double check your fuel filter and make sure its a genuine volvo one.

I had no end of issues with my engine and after a long time found out my in tank fuel pump was failing, the clue was the fuel filter was out of shape (vacuum). A sticky vaned turbo is a good shout too.

As you are after suggestions, I just thought I would throw it in the mix for your consideration, its not a diagnosis.

Default Update: Went to get a diagnostic. Volvo dealership ruined it

So the mechanics and dealerships are finnaly opening up, and I had the chance to book in a diagnostics test to see what's wrong. The dealership pretty much made it worse.

So on the day I went to get a diagnostics test done from the volvo dealership, I arrived like normal. The car drives pretty much normal, smooth with just lack of power. Got the car back in the afternoon, and that's when the problems started.

First, they didn't even want the mechanic to come out to talk to us about the problem they found. The first time that's happened. I've been to no other place where they don't want a mechanic to come out.
Second, the report diagnostic that they did give me is borderline useless. They outlined things that don't work, such as the DPF filter. Shame, I guess it's beyond cleaning cause I've got it cleaned twice now. They also outlined that their generic MAF sensor isn't generic and I need to get a generic one(How does that work?) and that the egr valve isn't fully working. Everything else is working perfectly, expect one thing that I'll get onto later
Third, the report itself is inadequate. Not only is there like two sentences about the things not working collectively, they also don't even give you the error codes anymore. What's up with that? I was only at a dealership some 5 years ago and they gave all of the codes to me, a 10 pages booklet of all the problems and information and all of that was very usefull. Nothing of that here!
And here's the biggest issue: Fourth. After a few discussions, they mentioned how the engine's very uneasy and sounds like a cylinder not working. I took it as a joke because why would a cylinder not work? I delivered the car with everything working. So then I go to pickup my car and indeed. The engines very rough with pretty much no power. And indeed one of the cylinders does infact seem to not be working. In the report is says "misfire detected." Car should display "check engine" at least, but my dash is completely clear.

The car's now in limp mode, barely been able to do 5mph. Had to get towed to get back home. The dealership should be ashamed. Made my drivable car literally unusable after a simple diagnostics test. They quoted me a £3500 fix for the DPF filter alone and with that they didn't even guarantee that the car will run after that. Never going there again. Makes me not want to get a Volvo ever again.

So now I'm one car down. Stuck at home and waiting till my mechanics around me open back up and see what can be done from there. And I'm never returning to that place. New filter is about £300 on eurocarparts and I'll do it myself.

So yea. There's the little update with a small rant. Never go to a dealership, not even for a diagnosis check to see how well your car's doing.

One thing that springs to mind is that on the 5 cylinder engines, there was an issue at some point that the wiring would break for the injector, I think it was either 1 or 5. That could be the cause of your current issue, especially if they've been poking around in the engine bay.
What I can't believe is that they left it like that when it wasn't that bad when it came in. I too haven't felt the love from the dealer network but I wouldn't expect something like that.

Shocking story. Conmen and thieves sheltering behind the Volvo brand. Disgraceful!

Default 25th November update, still nowhere

Crazy to think 169 days have passed since my last update. Progress has been made however the problem has not yet been fixed.

Over the last few months other mechanics have opened up again and we've been able to start working on the car slowly. What has been done:
  • A new DPF filter
  • New DPF filter accompanying sensors
  • A new EGR valve
  • And I think 2 other parts that I'm forgetting about

After the new parts were installed that were outlined as not working by the volvo dealership we were hoping that the car would run again like it should but no luck. Our mechanis said we should look for a diesel specialist who can induvidually check injectors. Found one not far and after some delays they got to inspect the car.

At first the diagnosis was electrical, however after more testing each injector was in perfect working condition, yet cylinder 4 still has no change in how it runs if injectors are swapped around or even if turned off, and when turned off the huge amount of smoke stops.

They wanted to do a compression check but they didn't have the sizes to fit my engine. I've found another mechanic that does and hopefully do it there.

The current hope is that some valves are to be blamed but still can't be sure. Otherwise will mean a complete dissasembly of the engine block right down to the cylinders. Will hopefully learn more next week.

So yea, pretty much a small update into the journey of fixing my car that has taken more than a year. Is it fooling to keep throwing money at a car that refuses to be fixed? Maybe, but I at least hope you get to enjoy reading this adventure D
