This is more of a FYI post.
3 weeks and 1000 miles ago I had the Transmission control module replaced and coded in a bid to fix the dreaded âCHECK AUTO GEARBOXâ error which has plagued me and the car for about 18 months on and off.
For reference:
đ 2013 ph1 200t lux
đ First started throwing faults at 120,000 miles / 8 years old
đ Now on 141,600 miles
đ Would drive absolutely fine when the error message was not displayed.
đ Would only display the fault message when ambient temps were above 20°c
đ Would only display error message after a period of driving (probably due to heat soak).
đ Would lose even gears only (2,4,6 & R)
đ OBD fault codes were âClutch motor 2 short circuit to earthâ plus lots of random electrical ones like âbattery voltage 12v open or short circuit to earthâ , âstarter relay open or short circuit to earthâ , âseatbelt warning light circuit open or short circuit to earthâ and âbrake/accelerator pedal positions, jammed accelerator pedal detectedâ.
Now I know the go to fix is first off a battery - Iâve had 3 batteries in just over a year (the 1st one got cooked when the BMS wire corroded through causing it to overcharge). The original battery is still being used in another vehicle so I doubt there was actually anything wrong with it in the first place.
I got a second opinion from another garage who confirmed what my mechanic said which was that the clutches were knackered. I decided to with my gut feeling (& the cheaper option) and changed the TCM. While it was at the Renault dealer they checked the clutch wear and yes while the clutches are worn (as youâd expect for a 140k mile car) they arenât worn out. đ.
Iâm not saying that a new TCM will fix everyoneâs CHECK AUTO GEARBOX issues, it seems to have fixed mine đ¤đź.
