Question about Mini Cars & Trucks
Ugh ! That\'s a crappy code. 2096 lean code. There\'s a few things to check. Map sensor. Smoke test at the throttle body and check the duck horn for leaks, and any others you may find. Check your purge valve for hanging open, and last but not least, remove the exhaust manifold, tape off all the openings and smoke test that.
Fix all the leak issues that you find. THEN, you must go to MINI to have your "adaptives reset" Even if you\'ve fixed the problem, many times I find the code will come right back after two key cycles. If that happens, you have to have the adaptives reset at mini.
This code is a pain.

Tips for a great answer:
Trouble Code: P2096
Downstream Fuel System 1/2 Lean
Trouble Code Conditions: Engine running in closed loop mode. Ambient/battery temperature above 20F (-7C). Altitude below 8500 feet. Fuel level is more than 15%. If the PCM adds downstream short-term compensation to long-term adaptive, and a certain percentage is exceeded for 2 trips, a freeze frame is stored, the MIL illuminates and a DTC is set.
