Mine behaved itself pretty well on the way to work.1/4 tank of petrol, 1/4 tank of LPG and halfords socket set in the boot, nowt else, I dont own a shovel. 
I turn the TC off going uphill as it just cuts power off and causes loss of momentum. The hill coming out of the village was the most challenging, looking out the side window in the direction of travel but managed to keep going, just. If I stopped I would have had to roll back down and try again with a bit more momentum.
Snow mode on most of the way, didnt get above 25-30 until the A12 - even then it was 40 max.
My TC only got turned off when I wanted to have myself some fun

I make a point of seeing how good the TC is on mine after all the hassles some people (aka Andy B

) have with theirs. Driving appropriately, mine just works. Yet all the BMWs around me are having to turn theirs off after watching them go nowhere (here the misfires for 20s, then hear the engine sound better, and watch the rears light up).
I am have racked my brains for years why some people say their TC works well, and others say its undrivable with it on.
MV6 3.0l auto, TC rear pads, non LSD, Dunlop SP9000 tyres at approx 32 PSI, plenty of weight in boot when icy/snow, often empty under other conditions.
