Bought a used BMW 320i automatic from a dealer end of May. I hit a pothole recently and the tyre on the driver's front nearside was funny so i took it in to a garage, expecting something like the wheel needing realigning or the shocks/suspension links having gone. (turns out the tyre was just over inflated). However in the course of diagnosis they told me the gearbox module/transmission module had an issue with it. They didn't appear to know much about it, and suggested i take it to a a garage which specialises in bmws. The thing is i've had absolutely zero issues with gear shifts and there's no warning light on the dash. Does anyone here know much about these modules? I'm under the impression that whilst the device doesn't cost that much itself, the gearbox would need to be rebuilt or replaced entirely which would obviously be phenonemally expensive. The car has until about august 25th on warranty but usually they want a quote first, and getting a diagnosis/investigation from a bmw garage (not an official one) will cost £60-£100. Just wondering if there is an issue, will it need to be replaced? I'm guessign eventually but I kept my last car for about 3 years with a broken synchro and it never got worse. Or could the obd message be an error, as there is no warning light on the dash? It was serviced and MOTed when I bought it and no faults.
