Mine definitely has the modified breather, it hasn't leaked yet and has PN0 vin. We are in Cornwall on holiday at the moment so when I get back I will be checking again as it will then be after extended motorway driving . ?It would need a couple of new owners, who after a fair bit of spirited driving, still have no oil leaks to be brave enough to drain the boxes and see how much comes out.
Big ask to be fair if you currently have no issues, would be very interesting results though.
On a separate note has anyone with the newest build dates been able to get under and have a look at the gearbox and see what, if any, type of modification they have on the breather.
That's what we're trying to establish by owners sharing their information.It’s been so long now have they fixed the leaking oil on all new mg4s?
There appears to be a pattern with the 2023 models not leaking according to the research here but I wonder if these cars have a modified breather or just have less oil put in them at birth or both as indicated by @Hagen. Dealers would not know and the Chinese manufacturer is certainly not going to tell anyone...they are renown for keeping secrets.
What we need is for someone who knows the 'old' breather design to check the latest model breather type and the amount of oil in the reduction gear box but I don't know how that can be achieved as I doubt dealers would be any help.
I applaud @Hagen for taking the time to do this research and it would be great if it is proven that those vehicles built after a certain date do not have this issue but my main concern is whether MG 'solved' the problem by a bandaid fix of just sharply reducing the amount of oil put in the 'box.
