Hi,

I have never seen a manual in English. You can try with AVL or maybe with our user Pagodefan1970 .
Viele Schraubergrüße - best regards, Dr-DJet Volker

Yeah, ok. Well i don't mind if it was in german, i will use translate if necessary. ;)
Ok, thanks i will ask him.
Oh, and actually i did open it up and cleaned the oxygen sensor. Didn't help and still shows just dashes.. The weird thing is, it still gets through the selftest, even with oxygen sensor unplugged.:O

Ok, just wanted to update. I replaced the oxygen sensor with a new one from ebay, and all values now work!
So it looks like it was just a bad sensor, weird thing it would still pass the tests.. I'm thinking maybe someone altered the programming at some point to make it pass even with faults.
