It seems to me that your scanner is only capable of reading OBD pids. Which are a waste of time for any serious diagnoses. You need A tool capable of reading proprietary protocol and data. Something like a launch. What country are u in? Maybe a nearby workshop can help u read the values

It looks like it can. I have the launch x431 and that works well.
Have u checked your overvoltage protection relay if all outputs are ok. And fuse 23. First restore power on black red wire to vvt solenoid

Your year model does not have k40. Look at lf fender next to Abs pump. There is a plug x26/25 look for plug B pin1 black red wire. That is power. I think it is wired to overvoltage relay . From fuse 23.

No mate. Look at pe07.51-u-2000-99wf
The diagram U looking at is for the later version.
Unless I am wrong? Do you have a module box? Ecu housed in a sealed plastic box with diagnostic plug inside? I think not.

Wis is not like epc. U need to look at the as of and up to dates on the diagrams. Use the diagram I refer to. When I talk about a module box mean a black plastic sealed box with a lid on it. Under the lid u will find HFM ABS and the k40 relay module and the diagnostic socket. U don't have this version? K40 and module boxes were only for later c200 240 models Tec not c220
