2007 S60 D5 Sport Loss of Power - Please Help

Orpheus14 · Jan 3rd, 2015, 09:49

Hi all.

Please help!!! The dreaded swirl arm came off. I repaired the arm and made a diy fix. Not a problem. But since then the car has lost it's power. It accelerates, but gradual. When I put my foot down it just slowly picks up. It runs at 80mph no problem but takes ages to get there. If I keep the revs constant ie 300 rpm it hesitates then picks up intermittently. Codes read by local Bosch service centre - Swirl Chamber/Flaps issue! They want to take the top of the engine apart before even finding what is wrong. I see a massive bill. I have worked on cars before, but this engine seems a nightmare with all the fuel pipes running over the top of the engine. Pressing the trip in and starting the car shows 040 code on dash - 02 sensor? I've been looking at EGR valve threads, but again, a tough job to remove. The car feels as though it's not getting enough air ie a blockage or something? Engine Service and Soot Filter Full message every time I start the car. The car goes to Cornwall regular and I have always given it a blast up motorway. I'm thinking that when I repaired the Swirl Arm I haven't reset something maybe?

Any suggestions would be greatly appreciated

Thanks

You need to repair the swirl arm
Properly and follow the fault codes. What does your repair consist of? Have you just made it so the swirl flaps are open all the time or does it work as it should, ie the arm connected to the motor and it calibrates it self properly? You could have damage to the swirl flaps internaly which is why they want to take the inlet manifold off so they can check the whole system. Be easy to repair it properly whilst it's apart. To do this the injectors need to be removed. You will need brand new injector fitting kits as well as the fuel pipes as these are one use only however some have reused and been ok. The gasket is rubber so should be ok.

You also need to see why you have soot filter full? Was there any codes relating to this, have you had a rise in oil level? If no codes are found then you may need to the volvo vida system to get correct diagnosis. Guessing becomes expensive and these cars ain't cheap to fix to start with.

With a swirl arm fault code in the system it will no allow a passive DPF regen.

Swirl Arm repaired as it should and calibrating, but no change!

Could it be the ECM needs resetting, although I have taken the battery off for a time but hasn't reset! ??? When you say damage to internals can you explain/describe?

If this link works these are the internal swirl flaps. Obviously the link arm connects to one end but it may not be actually doing anything if a part on the swirl flaps rail shall we call it is broken. So they may be in a different position to what the arm is doing if that makes sense. So a strip down is the only way to tell. They are a wearing item tho more the arm than the flaps them selves but it's not unheard of if the car has a few miles on it. If it were mine I would be taking the manifold off before anything else. It is fairly straight forward as long as the injectors come out easy enough its just the cost of the volvo parts that makes it expensive.

Disconnecting the batery wont help as there is an actual fault so as soon as the engine is started it will give the messages again.

Hi Graham.

I've been out checking around the engine bay and I disconnected the MAF connector (Don't know why exactly) and the connector that is close to the swirl arm. Something, I assume the fan, reacted and started to speed up quite dramatically. I plugged the connector back in and it calmed down. I took the car for a run and now I have some power back?

It accelerates much better but still nowhere near as good as it should. I'm going to take the air flow gubbings apart tomorrow and clean the MAF etc just to see if for some reason the car is getting wrong info as to air/mixture etc.

Hi
Recently had a similar issue, ('06 S60 D5 sport) we changed the throttle body and cleaned the EGR and it was better. but still got Soot filter message and intermittent low power/fault codes
Fault codes pointed at MAF sensor so bought a secondhand original one, but before this could be fitted and while driving it to work I had a loud "pop" and massive power loss. This turned out to be one of the turbo pipes blowing off, and breaking the bracket. This was refitted and repaired, we have had no further issues, the car is driving as fast and responsively as it ever has. We haven't yet fitted the MAF sensor, my tech reckons the pipe may have been loosening up / or the bracket had broken and stressed the pipe until it fell off
Hope that helps

We've had our 2005 v70 2.4d for nearly 4 years now. The swirl arm has never been connected in all this time. The motor thing moves but doesn't do anything. This has never given us any trouble and the car runs as well as the day we got it. Maybe the issue is not the swirl flaps.

Me too, well 3 years anyway. No issues at all. There is a stored fault for the swirl actuator out of calibration, but it has no effect that I have noticed.
I would think that the soot filter full condition is causing most of your issues.

Me too, I have bought the pin and lock washer to fix but have never got round to reconnecting it. I do recall when I had the original loss of power and it was when I was flat out in 6th and reached 3500rpm and suddenly the car cut out and threw up a message. I went to the Garage and they cleared the Maf sensor message and now I just don't take the car to over 3500prm in 6th, the off blip above this appears to be ok in other gears.

I generally set the flaps to the mid point and the car appears to be happy.
