So seems they are good for about 75k miles.
BTW, also had a couple of "warning chimes not available" errors that helped point to battery. Yours may not be electrical system problem... But worth checking.

Hi,
My alternator is brand new. Just replaced it last week. Ive checked the battery aswell. And no abnormality there, seems to be in a good condition. Havent replaced it tho. The car is 74k ish miles. I replaced many parts including,
- crank sensor
- cam sensors
- alternator
- waterpump
- all the belts
- all the shock absorbers
- other suspension parts
- brake pad, disk
- tensioner
- coils and spark plugs
- whole valve cover
- all the fluid flushed and replaced
- calibrate the injectors
And i forgot the rest.
Ive checked the voltage on the battery itself, and it was fine. The limp mode is intermittent.
The symptoms before limp mode are, it wont change gear at 3000rpm and keep accelerating then it pops up. With the 4x4 indicator. Dsc communication failure, brake indikator, and i forgot what else. I’ll attach the photo.
Regards,
Adera
