A few days ago my wife started the car, and a warning came up of a transmission fault, and not to drive. This reset on restart, and has been fine ever since.
Below is a complete scan, and the transmission module is showing a 'locked' fault code, which is component protection. No modules in the car have ever been replaced, the only thing done was the addition of a trailer module, and correct recoding of other modules some 8 years ago.
Has anyone had this before? Luckily, the fault appears to be electrical, not a mechanical fault inside the transmission. Hopefully!

I tried to code wrap this as normal but it keeps adding its own code wrap before the VIN and I can’t get rid of it and every time I try I get an advert with a woman in a red dress and an annoying tab across the bottom which I have to delete each time, bloody irritating!

I can’t explain why some units randomly go into locked mode for no reason but they do. The only way I know around it is using ODIS. Don’t worry though, they will make sure this sort of thing doesn’t happen with self driving cars as that would be… interesting..

Thanks for your reply! I know ODIS is used to unlock a locked unit, or match a replacement unit, but is there anything else that can be done to a unit that has a glitch where it locked once, then unlocked itself upon reboot? Eg disabling component protect?

I have had and seen ECU’s corrupt their coding and lock for no reason where even ODIS can’t get back in. A friend of mine had one of his techs leave the ignition on all night on a quite new customers BM :puke:and it corrupted every ECU on the car to the point the dealer could not recover them… he shut down not long after! I fitted a new component protected BCM to a late Passat and it bricked the ABS ECU, locking it in left hand drive. My ODIS dongle was away being repaired and I had to use another friend’s ODIS to unlock it. One of my techs fitted a new BCM to a T6, copying the coding from the old one and pasting into the new one; this made every ECU in the van except the engine recode randomly and I spent three hours on ODIS software and coding management getting everything back. A garage brought a Polo 6R in to me where they had used Launch to code in a new BCM (usual stupid washer motor output failure) and this locked the ABS pump in left hand drive and I could not get it back. It ended up with their TPS taking the car away to their local dealer who fitted a need ABS ECU. There are more too…
