[xc60fhx]

I have an XC60 2011

Took it to my local garage as the engine management light came on and lost power. it was a split turbo pipe.

after they fitted it i have now lost all the info like mpg, av mpg av speed
which was on the left stem also the oil warning comes on
telling me to add .5 litre even tho i have done this twice.

should i take it to a volvo dealer or is there someone in london that knows what they are doing to sort it out.

thanks for any advice
