Hello friends. I need egr off for Citroen C5 2009 1.6 HDi 109 hp

I buy new egr, so no faults codes, just P0401 - air circuit amount of air measured higher then settings - after i block egr with a blank metal gasket.

Thanks in advance!

Cheers!

The old egr have electrical problems. I buy i new one and without blank gasket in low accelerations the engine is not working well, smoothly. With the blank gasket is ok but i have the eror code show above and blower on

Maybe you have problems with leaks in the air inlet, or the MAF is for change...
Any way, if you want software EGR off, you must to post the dump from the ECU...

Here is the file. Thanks

Here is your file, the checksum is not corrected, your tool must to correct it... Which tool you use?
And follow the rule, after flash wait 3 min. with ignition off, then 3 min. with ign. on...

The car runs fine with @bobolin4o (http://www.digital-kaos.co.uk/forums/member.php/150906-bobolin4o) file. No errors and no blower after a few min. The MAF still read amount of air measured higher then settings. On idle the value is 274 mg and the MAF show 430 mg

@pike (http://www.digital-kaos.co.uk/forums/member.php/392477-pike) It is something different in your file?

Yes, the checksum is ok, but this is not important...
Galletto make it better than WinOls.
Regards!

BTW... Perhaps is good to give me at least thanks and reputation for the file...
And for mr. pike, of course...
We all living for those small things.
