E200 kompressor engine management light keeps coming
Hi, i currently have a mercedes E200 K 2002 model, and the engine management light keeps coming on, the normal genuine oxygen sensors are put back in after having the non genuine, and the alloy intercooler has been flushed clean due to it being oily but the very next day the light comes back on, my local dealer reset's the light and faults, but it comes up as unknown fault but the light turns off, and the next day the light is back on, does anyone know what it could be??? please bare in mind oxygen sensors had been changed but no difference and also interooler has been flushed clean

your co-operation will be thanked


i have left it running at the work shop, we have tried everything, but its still the same,


and also what is a Hot Fume sensor?


basically, i am not dealing with any of the 2, MAF or O2 sensor, but light keeps cummin on after ressting it
