Hi Gang,
Tomorrow I'll do a compression test and fuel pressure test.
Where to check first for the multi cylinder misfire?
I sure like this Ross-tech software.

I'd work on the other faults first. It's relatively pointless to try to diagnose misfires while you have pressure and temperature regulation faults.

Agree with Uwe.............. however, I would see the benefit of looking at the miss's going on each pack if one happened to be gross..........especially for vacuum leak tracing misfire.

IN VCDS 0x01-08-014 for all 4 zyl added up. and for individual counts 0x01-08-015 1-3 zyl and 0x01-08-016 for 4-6 zyl typically and this one being just the first field for 4 zyl.

It would be a good idea to inspect grounds at VC and under battery and to ecu module at CAL......
Check fuel volume/PSI and for boost leaks since it is obvious the diverter is stuck or the N249/vac line is damaged.

Check the MAF!

Could you clear DTC's and repost the scan for me?

Is the open circuit on the N75 from you unplugging?

Thanks guys
Jack I'm a bit confused on this "IN VCDS 0x01-08-014 for all 4 zyl added up. and for individual counts 0x01-08-015 1-3 zyl and 0x01-08-016 for 4-6 zyl typically and this one being just the first field for 4 zyl."

I'll clean the grounds and check for vacuum leaks
cheers
Hank

It means go into engine electronics ( 01 ) then measuring blocks ( 08 ) and type in channel ( 014 ) to see...........field 4 is all cylinders added up with a misfire combined totaled.

015 will be as follows in the 4 fields............field 1 is RPM then Cylinder 1 is field 2 and so on.

Understand now?

I would pull the oil cap at idle to see if it is sucking back on rather than dancing about like a normal 1.8T. If you find excessive vacuum leaking into the crankcase due to a faulty PCV that may explain the misfires in addition to the Pressure Drop between Turbo and Throttle Valve ... but as the guys mentioned the temperature regulation, N75 circuit and low battery (terminal 30) issues need to be diagnosed if they reoccurred.

Thanks for the clarifications
It is a Big learning curve for a old feeler gauge kind of guy

Compression test 200-195-200-200
Platinum spark plugs were black
cleaned the grounds under the battery

oil cap bounces up and down when loosen up while running but feels like it has a vacuum
after lunch I'll check N249/vac line and N75

any idea where to hook a fuel pressure gauge ?

thanks for the help
Hank

These cars have no test port so before the rail, on feed black line IN............... not blue which is Return.
Don't forget to check the FPR..........
Use the repair manual for safety and specific tools or procedures.

can u actually feel the misfire. whats the long and short term fuel trim at. also can u give us coolant temp and air temp when engine is cold. I think some of those had faulty coolant sensors
