Big motoring world fault - Audi Q2

[u/Adam21-]

I bought a car on finance with big motoring world fengate roughly 6 months ago, test drove at big motoring world and i pointed out 3 issues to them:

1. The shuddering in 1st gear (which they said is normal on audi diesels) I later found out with the healthcheck that its normal on Audi Q3's but not on Q2's.  I'm not getting quoted £940 to investigate with a likely £3000 repair bill after diagnosis for an issue I was told wasnt an issue when buying.

2. The windscreen wash wasnt coming out (they said that it just needs refilling or new wipers) but its actually blocked and needs unblocking which costs x amount

3. Theres a slow puncture on one of the tyres that I pointed out multiple times on the day, spoke to manager who discussed with the on site mechanic who all assured that it wasnt a slow puncture and there was no issue, but ever since that same tyre has been constantly deflating at a far higher rate than the other 3.  Often going from 40psi to 20 within a couple weeks.

All 3 of these issues were raised at time of purchase, all 3 issues I was told wasnt nothing.

After getting a health check by Audi under the warranty plan I purchased with them, I've been told by practically everyone working there that I've purposely been sold a dud car and have been royally screwed over and should immediately contact my finance company as theres no way big motoring world were not aware of all of these issues, and their seriousness when they sold it to me. The total estimated repair cost is going to be between £5000-£6000.

Any advice? Or anyone who can share a similar experience?

There's a FB page for disgruntled Big Motoring World customers, seems to be a common theme, lots of advice on there about who to contact at senior management level, my car from there seems to be the exception so far, touch wood!
