I have the diesel not the petrol, so no point in any engine stuff.
I believe they can have problems with the 2/4wd thingy, basically two fully open hydraulic circuits until front wheels are spinning faster than rear, detects and engages rear, know to have been a weak point on earlier mk2s. I think this system means you have to keep all your tyres on abour the same wear. A/c compressor pumps are know to disintegrate and pollute the whole system with metal shards. Check upper hinge on rear door as if its not been lubricated the pin will wear and rot and your rear door will fall of.
Apart from that seem to be pretty solid, bags of room for passengers and stowage, though it took me by surprise that I couldn’t get the bikes in it as easily as my old Octavia estate, I do it now by taking both wheels of and standing them on the bars and saddle using bungees to hold it down.
Loads of stuff on their forum but a lot of it ‘Merican so not sure if all points are valid. Hopefully by now all the lemons have been eliminated from their gene pool and only the good ones are left.
I like mine, suits my driving style ie not very fast.
Best of luck.
