£1k seems a bit steep, genuine parts can be had for around £200 so that's a nice little earner for a couple of hours work but i guess its london so half expected. As for a mechanic saying he doesnt have the specialist tool required, £20 or so buys the specialist tool required so if he cant afford that, he's probably better avoided anyway. what kind of water pump are they fitting? original with shroud or aftermarket without, some people prefer shroudless as it removes the same thing happening again, however be prepared for longer heat up times

best to buy 12 - 15 year old cars honda and toyota are best, easy and cheap to fix if they ever go wrong , prices are up though because people are waking up https://www.youtube.com/watch?v=-RTkroVirt0

It seams that older cars are in high demand and prices are up for good early 2000 - 2010 cars, people are getting pi$$ed off with unreliable modern cars and there high repair costs, Get yourself an old honda jazz, toyota corolla or rav while you can. You can get a whole car for the price of a modern dual clutch gearbox plus change back. The guy in this video knows what he's taking about

nox sensor b is the sensor at the rear sensor cost from skoda around £550 plus fitting cost on top cheaper to get it coded out and you can get it remapped at the same time, no more adblue filling costs either adblue systems are more problematic than dpf and egr valves imo

https://www.ecutesting.com/common-faults/volkswagen/dq381-mechatronic-causing-tiguan-dsg-gearbox-problems/ if you have a look at the above, it suggests that the problems are with earlier cars, so you would think that VAG have addressed the issues ? the 2nd link you posted about the improved dq381 is not from VAG though, but the above link suggests VAG have done something to fix things

most of the dq381 mechatronic failures seem to be on cars around the 2017/18 year or so if failures are not happening on newer cars, you would think VAG must no about it and replacement parts have been modified. they wont admit it though as no recall and owners are still having to part with there hard earned ££££

normally the horn is wired via the bcm [ body control module / basically the bcm is a pcb which controls things. if you can, check the wiring diagram to confirm the horn is wired via the bcm as that is normally the way VAG do it. as with all intermittent faults though you will need to test things while the fault is actually happening ie look for a live feed or lack of a live feed to the horn from the bcm

might save you a bit over the skoda price but not gonna be as cheap as the diy route for me though, it's more about, if you do it diy, you know it's done right and with the correct parts any ££££ saved is an added bonus

£25 - £35 for a set of ramps and £70 for dsg oil/filter kit [ ebay, ] ramps are handy for future work anyway no need for vcds, easier to just drain and refill through filter housing, although can take 45 minutes or so to get all the oil in there, kit comes with 6 litres oil but you only need 4.5 litres, easy job not sure what skoda charge but i'd imagine it will be at least double the diy cost

best to alternate keys, ie use key1 with a new battery for 1 year then use key2 for 1 year with a new battery the key not in use can sit with the year old battery in it just in case you need it and the key being used always gets a new battery this way you spread the wear on the expensive to replace keys

imo it would have been better to have gotten the whole adblue system coded out, normally along with a remap. adblue systems are even more problematic than dpf and egr valves

you would need to replace your pump with a modified pump which does'nt have the sliding shield [ non oem pump ] if your car has done 140000km it probably makes sense to replace the timing belt and pump anyway

NOx sensor 1 is the front sensor near the engine , NOx sensor 2 is on the exhaust near the back of the car. if you get them coded out they will both be disconnected, you need to go to a remap /tuning specialist unless you want to replace the sensor

EV running costs might well be cheaper but your 10 year old superb still has some value in it a 10 year old EV likely to be worth £0000 because the batteries are done and cost 70% of the cars cost to replace, so scrap yard time 😭

it's likely the NOx sensor that needs replaced, they are expensive to buy the best option is to get it coded out, usually along with a remap it will save you buying adblue, so depending on the mileage you do, you might get a fair bit of the remap cost back but more importantly no more adblue problems 😀
