Title: 1.8t - SAI Delete question - 16795 (P0411) Post by: TheRamon on May 18, 2016, 06:43:16 AM Dear Gurus,
I have physically removed the SAI Secondary Air Intake pump on my Seat Ibiza 1.8t. I have not removed / replaced my N112 and N249 with resistors. The car keeps throwing me a 16795 (P0411) - Secondary Air Injection System: Incorrect Flow Detected. (Obviously) I'd like to remove my SAI from the tune too, so my first thought was ESKONF. (http://i65.tinypic.com/2vnqsl0.png) According to S4Wiki there are two bit pairs that have something to do with the SAI. Byte 5 = NC NC EKP SLP Byte 6 = ULT UAGR SLV NWS SLP=J299 SAI PUMP RELAY SLV=N112 SAI RELAY Now for the funky part, I've heard that disabling / "resistor-ing" the N112 will mess up fuel trims. Is this true? Would I fix the CEL and Fault code just by coding out SLP? Or should I remove SLV too, and perhaps ULT=N249 Schubumluftventil too? (And then remove them physically of course) I might have missed something. Any ideas? Thank you in advance!

That's basically changing CDSLS to "0" right? Meaning you disable SAI diagnostics. What about CDSLSE? Can anyone confirm the following addresses for my file? I'm kind of doubting that I've found the right ones. CDSLS - 181A7 CDSLSE - 181A8 CWSLS - 181B7 Thank you in advance! ;D Title: Re: 1.8t - SAI Delete question - 16795 (P0411) Post by: 6L20vt on May 23, 2016, 10:34:30 PM Right, thank you!

But I cannot see any SLS related changes in your two files. Both CWSLS and CDSLS are 0x01 in your file.
Anyhow, I am guessing I must be right changing ESKONF as described in the first post, CDSLS=0x00, CDSLSE=0x00, and leaving CWSLS as is. Anyone disagree? Cheers and thanks guys!

I would use MSLUB and mslbas to solve the incorrect flow code if you have that defined in your map pack.
Title: Re: 1.8t - SAI Delete question - 16795 (P0411) Post by: TheRamon on May 25, 2016, 09:38:35 AM Ah right! Becomes clear now. I want to remove them yeah, since I have physically removed the SAI. So ESKONF and CDSLS is the way to go I think.
