Is your Mini Cooper S F56 (2.0 TwinPower Turbo) running rough from cold? 🚗💨
We plugged in an OBD scanner and found a Lambda Sensor 2 fault — and what followed was NOT a simple fix...
In this video, we:
Diagnose the rough cold start issue
Locate Lambda Sensor 2 (post-cat O2 sensor)
Show the real struggle of removing it (no sugar-coating!)
Share tips to help home mechanics avoid the same headaches
If your Mini is misfiring, idling badly, or throwing engine codes, this could be your fix.
⚠️ This job is doable at home — but be prepared for tight access and stubborn parts!
🧰 Tools & Tips:
O2 sensor socket (essential!)
Penetrating fluid
Patience… lots of it
