Gauge Issues with Maestro RR and Kenwood DMX905S in 2013 Jetta GLI

Post by MCDvoracek » Wed May 02, 2018 11:58 pm


I am overall incredibly happy with the Maestro RR and Kenwood DMX905S combination, as they preserve the essential factory functionalities such as MFD and phone, and add many more features than the factory head unit. I am having an issue with the gauges, however, and don't know if this is an issue with the Maestro or the Kenwood (or both). Some gauges work fine, others do not at all. Torque, for example, always shows zero. Boost/vacuum both worked initially, but now only show a static value of whatever it was at when switching to the gauge display. Intake air temperature and exhaust gas temperature initially showed inaccurate static values (0 C/32 F for EGT for reference). Speed shows significantly high when in MPH, but looks correct when in KM/H, as if the speed even when set to MPH is actually KM/H. Engine oil temperature, coolant temperature, and fuel pressure seem accurate. After performing a Maestro master reset through the Kenwood to try to resolve the issues, the speed and torque issues remain, boost shows a static value, and vacuum shows 0. The reset did seem to fix the EGT and intake air temperature issues, though, as they both now display expected values. Is there another reset or fix I can try to get all gauges working? Thanks!

You could try changing the engine type to one that doesn't match your trim. The engine type determines the data lines we read from (Vagcom vs can), so playing around with the engine types might yield you a little better result.
