^^ I think that "warranty main dealer" bit is true but only if the car has a full Renault service history up to that point, and indeed onwards to the point of failure if it's later but within 1 year. Otherwise they will always have a "get out" and say that something else that should have been done on a service has caused the failure.
Exactly. The warranty will mean nothing if the car itself is outside of it's warranty. The warranty would be directly with the dealership, which 99% of the time are franchised. I know from my own experience. I took my Captur back and to multiple times for an EGR related problem. The last time I took it to my main dealership, Renault themselves authorised the work. But the dealership didn't want nothing to do with the work anymore as they were annoyed that I went directly to Renault to honour the warranty on the car, but the car was out of warranty by a few months at that point. This was because of the dealership messing me around. In the end, I bit the bullet and just purchased an EGR and replaced it. Problem solved.
So just to note, warranty won't always cover you. Sometimes, the dealership will make you jump through hoops to get a resolve. Would you want to risk it and end up with an engine that they wrecked. Then have to go through hoops to get them to rectify their mistake.
Any car is labour intensive. The captur is no different than any other K9K engine. The cam cover has to be removed, hoses have to be removed to get to the crank locking hole. Then you have small room to get the water pump replaced and for the timing to be aligned correctly.
I understand the Megane is also labour intensive. But again, you will never know what you can achieve without trying. By taking your own time to do the job. You will ensure that the timing is perfect. Because you, me or anyone here would not be satisfied if it wasn't.
