Lidl corded Impact wrench 29.99

Wheelbolts are torqued up to around 110-130Nm, depending on the car, it should undo them no problem, 330Nm is over 200ftlb, which is very tight indeed

The quoted figures on these things are to be taken with a pinch of salt.

Sounds though like op is using the wrong sockets on his particular wheel. Probably has an alloy with the nuts set in deep so needs a deeper socket not just a standard depth one that wont reach

I wonder if a bolt that is torqued to 100Nm on fastening, allowed to remain for a few thousand miles and then undone, maybe the torque required to undo a bolt is greater than the torque that was used to fit it.?

Yes. Bolts seize. Exposed to the elements and often end up requiring significant torque

Unlikely to require 3 times the tightening torque, however.

Maybe we should try it out and see what the required torque is to undo them. What is worse is I think the Corsa wheelbolts are torqued to only 85Nm

Wig; this one is good; it's the one I have:

Just to dispel a myth there - whilst my cordless IW was supplied with two batteries, I've never actually run one flat and *had* to change it/charge it in the middle of a job. I keep both batteries charged and when one needs charging, it'll be done long before I've run the other 5Ah battery flat, ready to use again. Also means I can change wheels at the side of the road without needing to get a puncture near a power outlet

My cordless one goes flat over a month; it is designed to to cycle the battery. So it usually means it is flat when I want to use it; hence I prefer corded too plus the corded one has bags of power that the battery one does not.

Really? I could (rarely do) leave mine a month without any change in battery capacity. My old NiCad cordless IW would go flat over time, but the Li-ion packs on the current one don't seem to self-discharge.
