Engine Malfunction, reduced power, codes question

Nafy · 10-29-2017, 11:51 AM

Hello,

I was at the track yesterday. In my fourth session, my car stated to act weird. When I stepped on the gas, it felt like the car didnt want to move forward intermittently, engine cutting power, rear wheels losing traction. So I pulled back to the pit right away. On the second lap of my fifth session, warning message came on the idrive saying "engine malfunction, reduced power and take it to he dealer). I thought I blew up the engine.

I let the car cool down a bit before driving home and it was fine. My car is a e90 328i n52. The codes are 002C3A Lambda probe front catalyst 2, dynamic and 0029DC Cyl. Injection shutdown.

Can you help what the codes mean? Thank you.
