I always appreciate when members follow up with the solution within their threads.Thank you! I have my BAS/ESP lighting up after about a mile drives distance, no loss of boost, but considering a wheel speed sensor, like 180 mentioned. I'll look into more once out of storage this spring.

I did notice though, this fall before storage, one of the two previous owners at some point had a resistor on the drivers side tail light. I'm guessing an LED upgrade with tail/brake light? Any how, it was cut and the wires were hand twisted, barely holding to together, so I'm wondering it might have generated a systems fault. We'll see.

Thanks again, and I agree, this forum is phenomenal, great advice here!
