As said, every time I plug it I get airbag, gearbox, hdc all sort of light come up when iid is plugged. This was never happening before, I keep the tool up to date (maybe I shouldn’t have) 4.4 tdv8 2012 I have. All I can delete except airbag which needs I leave the car and lock down wait until all goes of (10 min) then come back in and start while iid is plugged or unplugged and airbag light is off. What is that possibly? Any one had this issue? Range Rover 2012 4.4 TDV8 - current

This relates to the mongoose type cables, but maybe worth temporarily insulating pin 13 and see what happens? L405 SV Autobiography LWB SDV8, finished in Aston Martin China Grey by ETO division.

Hmm this #13 seems interesting. But being this genuine iid and it was not doing before such issue (cannot remember when it started) should still remove number 13…I don’t have this with cheap obd

I still work with it but gives me heart attack (minor) each time and thinking what if this time I cannot erase them  Range Rover 2012 4.4 TDV8 - current

Maybe worth asking Pat at Gap if anything would have affected the IID when it was recently updated. Maybe worth just masking tape over pin 13, purely out of interest more than anything.
