🔧 Mechanic's Notes
- Electric water pump and thermostat are the E70 N55's headline service — do them together before they do you.
- Valve cover and oil filter housing gaskets drip onto the belt drive; a soaked belt can get dragged into the front main seal, so don't ignore it.
- The plastic charge pipe cracks under boost, same as the sedans — aluminum fix is cheap.
- At higher miles, valve stem seals show as startup smoke; on air-suspension cars, listen for the rear compressor working overtime too.
Field patterns from a working mechanic — diagnose your own car before buying parts.
