I received the following codes after scanning my car when the check engine light came on. Any ideas what could be causing this and if I could clear the codes without any problems?

206E - Couldn't find this in the guide (no description)
200F - G3/4 (Right O2 Sensor, before TWC[CAT]) (P0130)
4315 - Fault in CAN communication with control unit a1 (instrument cluster)
4600 - The voltage supply of circuit 87 has undervoltage

Thanks for the help.

Pre Cat O2 sensor is cycling too slowly on bank 1 - replace.

Could I do this myself in my garage? If so where would this part be located and could I order it online?

Yes - relatively easy




You will need one of these to possibly hit with a hammer. O2 sensors rust into the manifold. usually 22mm

You can buy online from RMeuropean or similar. Do not use generics!

Thank you so much for your help, I think I might tackle this one myself. Is the replacement direct plug and play? I read else where that there is a wire that runs within the engine compartment. Where would this plug into? Are there any DIY threads with pics?

It's dead easy as long as the old sensor unscrews OK. It's plug & play. There are no DIYs with pics. Just a stupid one on a M271 in the stickies. More beer than instruction.
