Can I get a full refund on my faulty car?

I bought a 2007 Nissan Qashqai diesel from a SIMI dealer on Sat. 7th and 25 hours later into ownership it has developed the four following faults:

A) ABS fault light on dash after first test drive - solution agreed and accepted - a fault nonetheless.

B) Faulty driver side rear window - window does not rise up again after being lowered - this was noticed 1.5 hours after purchase.

C) Red engine warning light on dash after 2.5 hours of purchase - Nissan manual advises car needs to be reviewed professionally ASAP - thick white smoke from the exhaust.

D) 3.15pm Sunday 8th Jan. - car simply will not start. I have advised the dealer I want the car collected and a complete refund issued.

I believe I am entitled to do so under current consumer law (not of merchantable quality and unfit for purpose) - can you confirm?

Thanks.

A few questions about turbocharging...

Hi, I have a few related questions please about turbo petrol cars. I'm thinking of changing my car soon and might actually go for petrol over diesel this time, mainly due to cheaper purchase price and reliability concerns about diesel cars when warranty runs out.

Do modern turbo petrol cars typically have EGR valves and Dual Mass Flywheels, two parts that often cause problems in diesel cars? Also most turbo petrols of today don't have particle filters, do they?

Final question please: why, if petrol is meant to have more potent power than diesel in many ways and I know petrols can generally manage higher revs and top speeds than diesels, do turbo petrol cars usually have much less torque/pulling power figures than equivalent sized turbo diesel engines? I've found diesels to have much more pulling power and responsiveness at speeds that are actually legal and under the limit, than petrols, in cars I've driven. Why is this when both types have turbos?
