Normally I have been able to reset my cel from a lean condition (most likely from an air leak in the IM when I re-installed it after a carbon clean) set the readiness indicators by driving around and pass emissions. This year I had 2 that would never set, one of the banks post cat readings and the SAI.
SAI’s are about $700 and do not exist (or they say a three month lead time - which I have found to equate to NLA). I tried a couple used units, both arrived dead, even though they said they were tested.
As a last resort I decided to get the JHM tune (including the SAI delete). While I still get my lean CEL, VCDS says the readiness indicators were all set except the SAI (oddly enough since I expected that one to be set due to the SAI delete).
Off to the inspection, and it fails again due to readiness.
So, I am about to do 2 things:
Uninstall the tune and see if I can get all except the SAI to set and get it re-inspected
With great resistance, put an order in for an overpriced SAI, since I do not plan to drop the engine and replace the cats any time soon
Does anyone else have any advice or maybe an explanation why the JHM tune would screw with the readiness faking me out that they are set when they are not.
