Hey guys picked up a second hand hex can and when I run the test on my b6 S4 it says K1 ok
K2 ok
can Not Ready.
Need help please.

That's entirely normal on a B6. It doesn't do diagnostics via CAN, it's strictly K-lines for diagnostic communications.Hey guys picked up a second hand hex can and when I run the test on my b6 S4 it says K1 ok

There's no long coding in any module of a B6 A4. They all use old-school regular coding.Ok , so does that mean I can't access long coding with my car?
At most on the fog lights. LEDs weren't really a thing yet when the systems in B6 were designed.It's an S4 but that doesn't make a difference I guess. I'm just trying to turn off cold diagnostics for some of the bulbs on my car I've changed to LED's. Is that possible to do without long coding available?
Have you fitted resistors in parallel with the LEDs?Ok guess I just have to hope that the led bulbs flickering when I turn the key on doesn't kill them too fast. Thanks for your help I appreciate it.
Sounds like the resistors have a fractionally too high resistance which isn't cleanly "fooling" the cold diagnostics. Remember the resistors will get very hot when the bulbs are on, so mount them somewhere appropriate.Ya some have built in resistors, others I installed so I have no bulb out warning. They just flicker when you turn the key on which is what I wanted to stop by turning off cold diagnostics.
The pulses IIRC are at reduced voltage (so incandescent bulbs don't generate anything visible).Let me rephrase it it's actually a strobe effect not flickering. The ecu sends out a few pulses to check the bulbs, it looks cool but Apparently it kills the LEDs quicker.
Agreed. The brightness of LEDs has traditionally been modulated using PWM techniques, and I've never heard of that affecting them in a negative way.As an electronics engineer of over 40 years I fail to understand why these pulses would "kill" LEDs
