The reason why the group is called rusted jacket is due to rust build up under the front seats. Apparently they didnt apply antirust on the seat base in the early models from 2012-2013

Mine is 2015, no such issue

Sticky door pull is unacceptable though, but its just a <100 bucks fix for all 4 doors

I'm still running a 2009 E60, ok jer. It had a slow coolant leak, which I found out is actually from a leaky overflow hose. Cheap fix

I did had a 5 figure repair bill on the E60's gearbox, but that's due to bmw's stupid advise of "lifetime transmission fluid". Expensive lesson

Also had a 2015 F30, which also leaked coolant. The overflow tank bleeding screw sudah reput.

Having said that, both ada oil leaks and can be fixed by changing valve cover + gasket

Recently added a G20 to my collection, so far still too new to tell. But from both older cars, you can tell its due to bmw's way of running the engine at 110c

Will probably reprogram the G20 to run at 90-100c once the warranty runs out

Yup. After my ZF6 died, for my ZF8 I just changed the fluid outside at 40k km even if its under warranty. The SC wouldnt know anyway

Touchwood the ZF8 is still silky smooth

G30 any year also uses the updated B48 engine, but still has coolant leak problems.

3 areas to look out for which is the coolant flange, oil filter housing, and cylinder head return hose.

These are all made of plastics and can crack over time. There's aluminium equivalents for these from china but most workshops dont recommend using them

Maybe a better solution is to use original plastic parts + reprogram the engine to run at lower temp ~90c+

Ooo looks like M50. Your car ka? What model?

Yeah from N52 onwards can see alot of cost-cutting exercise. N52 silver top vs black top already alot of parts become disposable.

Silver top has magnesium valve cover with modular PCV. Black top has plastic valve cover with built-in PCV. If PCV membrane torn, can throw the whole valve cover and replace new

N20 even worse. Even the oil pan become plastic. Top plastic, bottom also plastic.
