I'm posting this to make everyone aware, if you aren't already, that these Volvo V40's with the Ford designed Powertrain MPS6 Gearbox can suffer a complete clutch failure costing thousands to repair.
Our 2014 V40 with less than 65,000 miles on, was performing strangely at first, with a definite delay when pulling away and poor fuel economy. One day the car failed to start which turned out to be a problem with the battery and starter motor. However when those got replaced, the gearbox gave an error code suggesting a stuck fork. It went to Marshall Volvo of Cambridge who after two weeks offered to change the gearbox fluid for £800 to try and fix the issue.
After discussions with a local gearbox specialist, we moved the vehicle to them and got the gearbox re-conditioned.
On strip down, the front clutch plates had suffered a complete failure where the teeth around the edge completely folded over.

Further to this the clutch basket has suffered some molten material landing on it

The gear box was completely re-built with all new parts, new Mechatronic fitted and re-programmed via Volvo at a cost of around £4000.
Having written a full technical report to Volvo UK, they were not interested in contributing towards costs in anyway despite the unusal nature of this gear box failure.
I will also add that Marshall Volvo Cambridge were extremely poor in their attitude towards us as a customer. It took them two weeks to even look at the vehicle, when they did they just told us what the computer told them, maybe change oil might fix it. No clue what the problem really was, no offer of a courtesy car, very disappointing. It took three months to finally get the car back on the road.
Be warned, if you're driving a Volvo V40 with nearly 65,000 miles on it, and it has the MPS6 gearbox, sell it now before it fails.

My local Volvo dealer are fighting for a manual flywheel to be paid for, 3rd one in my 9000 mile ownership. To be fair, as a dealer, they have looked after me really well with loan cars etc, but seems head quarters are pretty useless...

Did you ever have the gearbox serviced? These boxes have a strict 4yr/40000 mile service interval in the Fords that use them. The reason for this is the swarf from the clutches contaminates the oil causing the clutches to begin to slip over time. My old V40 with this box had been serviced once before I got it and when I went to ask Volvo to service the gearbox the second time they told me it didn't need it as it was "sealed for life" (all of their other boxes are). I ended up going to a specialist elsewhere as Volvo messed something else up but the specialist serviced the gearbox (not an easy task as they are very sensitive about oil level) and it made a huge difference to the way the car drove, like you said your one was, mine was a little lazy pulling away before, it was hugely improved afterwards.

It might be worth reaching out to the manufacturer of the gearbox (getrag?) to see what they recommend as a service interval for the box, if Volvo have ignored that service interval, it sounds like the issue is entirely on them. It wouldnt be the first time they got service docuumentation wrong.
