R55 – MKL lights up but no error code exists…(emission-related diagnostic information)

Ahoi, recently owner of a Clubman R55, 120 HP gasoline, automatic, built in 2008. Unfortunately with the following problem, shortly after the purchase, the MKL lit up, so short to the workshop, allegedly no error code available, nevertheless code deleted (??), afterwards the lamp was off. The car drove and drives without any problems. After a good 1500km the MKL went again. Then bought me an Icarsoft diagnostic device (I bought for the Volvo, works great). Then the following display in the diagnostic menu: “Read error code” stood: The vehicle has no error codes With “Delete error codes” then stood: Delete the emission-related diagnostic information, are you sure? Just a bit helpless, especially since the car runs great. Could delete the code, but after a day the MKL went back to…then deleted again, probably again tomorrow. If someone had a tip I would be very pleased. Or drive to Mini and read out there, suspect its device can be more than mine… 😉 Thank you very much. Best greeting.
