Hi guys
Thanx for responding!
What happened was when I started the car one morning after a very cold couple of days there were alot of smoke coming out of the exaust, I let the engine run for a few min hoping it would stop but it didnt, instead it started dumping out oil throuhg the exaustsystem so I turned the engine off. I tried restarting the car again a few min later but it wouldnt start and thats why I desided to change the oilseparator and hoses, I even pumped out the remaining oil and put in new oil. Still no start so I ran the carsoft but since this was the first time I diagnosed the car I don't even know if the error codes I got are resent or from prior to the freezing problem.

Does the nr prior to the error text mean anything?
I took my time reconnecting everything so I don't think I've mixed the connectors, but I can always double check.
If a connector/sensor was to fail/broken how can I test it? like MAF and throttle valve for example? There suposed to be a power supply for the MAF sensor.
Could this be a broken ECU or is the ECU just reporting errors from the athers units?
"160 Signal after KAT Bank 2" what is KAT bank 2 refering to?

Sorry for the long text, but I appreciate any help.
