im having some work down & the mechanic said he can use the VAGCOM to scan my whip. ive been having some boost issues with my KO4, as im only boosting to 15psi. I tried swapping in a N75F & it worked great- 20psi- for a week but then went into a "type" of limp mode even though i have a AEB. I put the stock N75C back in & im back to 15psi. I know the cold could be a variable too. Ive checked plugs,MAF, O2 sensor, DV, hoses, pressurized system etc....i can go on :)
anyways ive read about different blocks to check for regrading boost etc.

block 115 - requested boost vs. actual
block 032 - see how much the ECU is trying to adjust furl trims
block 003 - what type of reading the MAF is getting
block 011- coolant temp reading - going to check this since im there
block 015-016 - ignition coils
block 002 - MAF readings - i checked this & it works fine...
bock - - O2 sensor - i checked this and works fine.
ive read about a "throttle body adaption" to make sure its opening the correct %. how do you do this? I assume i can just have the mechanics put all this data on a flash drive or something. he said hell scan whatever & i can do anything i want with the info.
Are there any other blocks i should check for? i got some more reading up to do to double check everything. i want to have everything scanned that i would need to have. THANKS :)

what is block 111 for?

i didnt get anything scanned yet. i wanted to have a list of blocks so i can have them scanned all at the same time.

I replied to your question in the other thread also. It's the N75 valve adjustment values like 032 is the fuel adjustment values. I'm just asking what it is for my own collection. I'm thinking if the values in the block are fairly close to 10, then your N75 valve is bad.

I'm driving around with a bad N75 valve and the values are: 9.9% 8.0% 9.9% 9.0%

My friend has a good N75 valve and his values are: 0.0% -1.9% -0.3% -0.6%

haha had both windows opening & was reading both of your responses..im loosing it. i need to go home from work NOW haha.
Since you are driving arond with bad N75, what is happening? Not boosting high enough, WG is opening prematurely....etc...

When i get scanned, is there a save button or somthing where i can save the info on a flash drive or to excell? i see when people postes their readings on here its usually in excel or a chart format...

you know anything about the "throttle body adaption " test thing? to make sure its open the correct %

What happens for me is I don't boost above 14PSI (used to boost higher) and boost comes in faster than it needs to. I'll be boosting partial throttle (1-3PSI) and it will just settle down back to 0PSI.

For block 111 just write down the numbers in Notepad or Wordpad and save it.

thanks for the help. what about other blocks that i get scanned? Can i just save all the ones i have scanned at once to word/excell?
