Hi to all,

I own a CLK A209, 200K (engine M271.940) Cabrio, built in 2004. With BRC LPG system.

During a OBDII check, I found this code error: P0410, Secondary air injection (AIR) system - malfunction,
It appeared only 2 times and not recently.

I have started finding information about that and sincerly I do not undertand if my engine (271.940) has or not has this subsystem.
I would check the relay but in the engine compartment fuse box I do not have the relay (see picture below, red circular lines).
PS: the red cable is main 12V+ source for BRC cpu.

So, I have had this error, for two times, now I do not have this error anymore but I'd like to know if my engine have this system (Secondary Air Injection) or not.
If not, maybe the error was a glitch.
if yes ... maybe it doesn't work because some stupid technicia had removed the relay for some reasons and forgot to put back?

Thanks, to all.
Massimo
