Lost of power after DSG gear change?

Recently I have noticed my car lost power when it change a gear up, for example from 3rd to 4th. It feels like you put your car into natural.
It had done 103k miles. Is it an age thing or just need a specific DSG gear service

If you haven't had your gearbox oil done then it really needs it every 50k or so. You really want to get it done asap.

I know bad oil can lead to funny auto box issues like slow changes etc.

If you are around Manchester, AwesomeGti did mine for about £180 or something and put all the clutch adaptions etc in. Did a cracking job and even though its only done 60k miles I was really surprised at how much smoother the gearbox worked after that service
