No Overdrive – Bad Solenoid in Valve Body
A vehicle came in with no overdrive and code “00258 Solenoid Valve 1 (N88) – Open Circuit”. Using VAG-Com software we diagnosed it as a bad solenoid in valve body.
Solenoids are not serviceable separately, so we installed a new valve body, adjusted and readapted the transmission and throttle body with Vag-com. We road tested the vehicle. No codes returned and transmission shifts properly.
