What life have you got out of your OEM battery so far??

5 years on the MKV 2.0 TDI. First signs of problems was the SatNAV unit not talking properly to the dash MFD display. Dealer couldn't make the link, until battery went completely dead, and the reset fixed the issue until the next low voltage event.
