it took me a few hours to finish mocking up some heat shields in order to put my exhaust back in to fire up the engine and try this out. all of my SAI faults were gone, but i still had:
17881 - EVAP Leak Detection Pump
P1473 - 35-00 - Open Circuit
i looked back through the s4 wiki and realized that there is no ESKONF bit pair to disable circuit diagnostics for LDP. i did a bit of research and found
this thread in which P1473 is discussed. it seems that some were able to eliminate the circuit diagnostics by setting codeword CDTES=0, so i tried this next (i already have CDLDP=0 in my binary). it did not work.
so i took the cheesy hack way out and set CLALDPE=0. i understand this is the "error class" method of masking out the fault, but i couldn't think of anything else to try and it sounds like others have been forced to resort to this as well.
for completeness, the addresses for these codewords in my binary are:
CLALDPE 0x107BB
CDTES 0x181B2
i'm not sure i saved any money with the hundred + hours that it took me to perform an immo delete, load the manual trans binary, and code out all the emissions stuff, but it was impossible to resist the temptation to learn this stuff myself once i saw how much info was contained in this forum. and it's hard to put a $ value on the satisfaction of learning a new automotive skill.
thanks again for all of the help. i really appreciate the fact that message boards such as this allow beginners like myself to benefit from the knowledge and experience of others. now i need to finish heat shielding, get some miles on this thing, start logging some data and thinking about a bit of tuning!
