Build Journal: maintenance program
Getting old doesn't have to be draining.
I bought my M5 in July 2020, by September I was losing half a liter of oil every 1,000 kilometers and my undertray was spoiled in an oddly specific pattern.
The oil cooler was cracked.
In this entry, I document the original failure points of the OE unit, the replacement options, my unboxing impressions of this improved oil cooler along with installation notes.
Enjoy,
