Very strange fault code

B4 soon

Petrolheads
Got into the car last night and CEL came on straight away after start up. Just checked there now and getting 13 long and 9 short flashes=code 139. What the hell is this code?????
 
Thought that dave.Maybe REV-Ds only flash obd2 codes. p0139 is rear lambda slow response though is it not. Ive never checked if REV D has one or two lambdas
 
1st lambda in RevD B4 is just on exh mani on no.1 cyl (passenger side on front), 2nd is just behind the downpipe.
1st is regulating probe (air/fuel ratio)
2nd is diagnostic

How do you mean 2nd is diagnostic?
 
I mean 1st lambda is setting air/fuel ratio and 2nd is checking the emissions behind the cat converter, setting mixture for running on idle to keep cat converter warm. both lambdas are working together as a team and setting/checking mixture. If something is wrong with one of them AFR is getting wrong and on the end of the day your engine is fu(censored)d.
