I have a similar file from Alfa Romeo 166 2.4 JTDM, with a switch on the same spot - but with disconnected EGR I still get P0401. Does my file have more switches? Did I do something wrong? File Attached.

Me too. Fixed in engine in map "engine speed and injection quantity dependent base map of max/min deviation value calcuation".
In mine is ast address 1C4ECA. Check image:



Set all to 1000. No more P401. :thumbup:
I have a 166 2.4 20V 185hp too!

Hi guys,
i've an EDC16C39 on Alfa Romeo 147 1.9 16V 150 Bhp.I've read all the post,but i can't find the egr switch to unplug the connector without error or map recovery.
Someone can help me?

Thanks and sorry for my bad english!

No one?I think i've found the switch but if can i have confirmation it will be better :)

Post your ori file, then we will tell ;)

Hi guys I'm looking for EGR switch, where can i find it? I will attach original file, Thanks in advance :angel:

Try to disable EGR by hysteresis. I think i found it at 1C41C8 and 1C4294. Both 25x1.

Thanks for reply man, I managed to disable egr by hysteresis, but I still keep getting bloody p0400, tried to disable it on fault code table, I thought that I found code switch in 1c8b9b but no, code is is still on car. there is something I am missing, adress of the code that i give you give's me 55 value in 8bit mode but what numbers should I put in to disable that code? :)

Put to 0 next adreses 8 bit
1aac14 , 1aac15 , 1aac31 , 1aac32 , 1aac33 , 1c85a0 , 1c85a1 , 1c85bd , 1c85be , 1c85bf

tested and working! magic thanks man. Maybe you know if its possible to switch off dtc codes for abs unit from ecu? I have problem when i reach higher speed about 70mph one of my front abs sensors trows me a codes C0040, C0196, but when I restart the car all is ok again until I reach 70mph I know best solution is to change the abs sensor, but maybe its possible to just switch off the codes?
