Loss of power.
Hi my 2010 D5 keeps loosing power when accelerating. No warning lights, no fault codes. It does this probably 30% of the time. On accelerating from low speed almost no power. Foot hard down, it revs to 3500 then changes gear. Up hill max 40mph. Then after 20secs - 1 min, whoosh, engine growls and the power comes in. (feels like no Turbo.) I have visited one independent Volvo Garage and they reported no codes shown. Visited 2nd independent Volvo Garage and they also found no faults. Sent me away,explaining they had reset all codes. I returned 5 mins later with same problem. The mechanic accompanied me and the problem came back. He plugged the car back in and came back with a sheet of paper explaining the Cat temp sender was faulty, also pointing out this would give a lack of power. It is booked in next week for 2 senders (They need to be fitted in pairs).
I'm no expert on modern engines but cannot help feeling this isn't going to sort the problem. I have read loads and watched YouTube. I presume the V70 has a variable fin turbo and suspect the actuator is sticking. Any help would be great. |

I was on the understanding that the turbo actuator was electrically controlled so a diag machine should be able to activate it.
I would have thought a fault code would be present if turbo was fault, overboost etc.

I had an actuator stick on my 2003 D5 i use to have and threw all sorts of sensor codes up. One garage tried to move the actuator and it was stuck solid. Sensors helped a little so may have been faulty also, who knows. I ended up getting the turbo reconditioned, about £600 (a few years back) all in with new oil and filter and a 2 year warranty. I was quoted £1200 new with 1 year warranty. I had a day of work, drove to have it done but still quids in at the end of the day. The place that reconned mine had a mate next door with a garage that did the job but as they work closely I got a quote for the whole job done and paid each seperately. Took about 3 hours in all., saved time waiting on postage of parts to and from and had a nice drive home afterwards.

I'm at a total loss what to think. They've put smoke in the system to check for vacuum leaks etc. No fault codes makes me think mechanical, but surely we should get some error codes up. Maybe a turbo failure imminent.

What's needed is a road test while connected to a diag machine. Reading valves from turbo, fuel pressure etc when power loss occurs.

I had a similar problem and it proved to be the temperature sensor that screws into the exhaust, the part cost about £90 and was fairly easy to replace. It might be worth checking this first.
