Our 2nd car is a 2012 Ford Fiesta and we love it.
Last Sept when the battery was running low, we got a bunch of error messages on the dashboard.
The Ford Dealer put a new battery in and cleared everything but said we also needed a new Transmission Control Module. They didn't have one and 6 months later they tell me none are still available and may not ever be made again. What should I do? The car has been running fine during the interim.
Thanks
Mike
Sometimes the TCM just needs to be flashed to clear codes.
I'd take it to an indy shop and see what they say.
I'm speaking as someone who works in the industry and had that happen with my Passat.
