Check Engine Light Recurrences?
Our program parameters are well within operating ranges (Stages 1 & 2 ) and should not cause MIL lights or engine protect-mode (shut-down). Turbo Diesels however may have “Adaptation” values that exceed fueling requirements or injection timing that may cause protect-mode (shut-down). Faulty MAF sensors or gas MAF on a diesel can throw a code too. Good reason to drive car to us. We will drive car and log vag-com data (MAF, boost, and injection timing).
