DTC window PRA

[mr-alternative]

I got the check engine light one these days in my EUDM Type R with Kprod PRA Ecu.

At Kpro Manager it showed me up "1 error", but in DTC window it showed up no error code.

Going to the next workshop and they read out: primary oxygen sensor - high voltage.


So why does the Kmanager dont showed me up the error code?

I used the stock K20A2 Ep3 map and stock EUDM oxygen sensor.

record a datalog next time the error is showing and post it here.

got the problem fixed by replacing the primary oxygen sensor.


But these days got a bit colder here and now i have a rough running engine 2-3 times when the engine is warming up by driving in the morning.

I recorded the datalog this morning, but couldnt upload it here for some reason as a attachment.
