Don't bother with the 3rd party warranties. It's easier to wring blood out of a stone than it is to get money out of them.
Friend had an issue with the valve block on his automatic gearbox. Pug dealer quoted circa £1700. No issue, he has a WarrantyWise policy... and it has quentin wilson who fronts it... so what can go wrong?
Well firstly they refuted the claim, it's a DSG or SMG gearbox and those are specifically excluded. Firstly DSG is a trademark of Volkswagen Audi group & SMG is a trademark of BMW. He has a bloody Peugeot. On top of all of that, it's a slushbox, not a twin clutch auto.
Then they refuted the claim because under the terms, it's only the parts inside the gearbox which is covered, the valveblock is outside the gearbox

Had to argue with them over this, took two weeks and even Quentin got involved. I literally took a photo of a tupperware container, with my car keys taped to the lid, closed the lid on the tupperware and asked if the keys are inside the tupperware container or outside. Yes seriously!!
They then sent me a servicebox diagram of the gearbox... which then just proved their own theory incorrect.... it was nestled deep in the gearbox. Own goal... claim paid out right?
Nope, they just outright said we have gone as far as they can and aren't willing to talk to us any further

Sent a "letter before court action" for the full amount. That got them talking again, eventually paying out for the full amount.
It shouldn't have to be this bloody difficult!!
