Can you help ..my v70 has a intermittent problem .limp mode or loss of power..she drives fine first on start up/cold start turbo kicks in and all the 205 horses seem to be working, then after about 15mins driving she just losses power and the turbo says no ..no whistling sound and takes forever to get to 55mph .. on a cold day has been driving fine.. I've changed new fuel filter oil chance air filter change cleaned mafs with maf spray ,ive cleaned the egr with egr spray and pipes with a pipe cleaner, bit clogged with soot egr valve nice and loose and clean now. ..thought I'd fixed it then she back to old tricks again after about a 600miles ..ive found lately when we've had - 3 temperatures she drives fine all the power there turbo whistle etc?? Any ideas 💡

 

Hello.
Today went to volvo dealer for same problem on a 2014 XC70 D5.
It was turbo intercooling related.
Last week my mechanical say that code (P00BD) was about MAF, so he cleaned and check the underbody hose for turbo. Everything works fine for another 15 miles then the problem returns.
Today at the dealer they check and find the problem. A little leak in a hose that opens with some temperature. The diagnostic was USD $ 160.
The repair its usd $ 300 more.
The hose part number is 31370208 or 30792885.
Bye.

 

Thanks.. I have a mechanic looking into it Sunday.. I think he mentioned a pipe might be perished near the exhaust that controls tems pressure etc ..
