Code p1850 98 jetta


It is an communication error for your drive train system. It communicates on a can bus and is not receiving a signal, possibly ABS. To fix it will need to go to a dealer or V.W. specialty shop who can work on the computer system.

Well, if you do not want to spend thousands of dollars in repairs, then I would recommend getting your vehicle PROPERLY diagnosed and repaired before any other things get destroyed by continuing to operate the vehicle with warning lamps lighting up all over your dash TRYING to tell you to get it fixed!
(this should have been fixed when it started out...BEFORE all the other codes showed up.)

DTC P1850 is a serial data bus malfunction. Your computer network is not working properly. You need a scanner that can communicate on the ENTIRE computer network in your vehicle to find out the cause of these problems. Please note that a generic OBD code reader CANNOT perform this function. Volks Wagen is a whole breed of its own and requires special equipment and software to diagnose and repair.

2002 jetta tdi, got code po 725, p1780, p1850. Transmission starts in second gear and will not go in to fourth gear. Any help? Thank you


i had a few of these pop up. The PCM and the ECM had a brain fart. Have the codes cleared and if you have the same luck as me all will be back to normal. That was the fix...
