Just done a gearbox change on my 4e-fte and there was a knock that felt like under neath the car. Since then I don't know if it's a coinsidence or not, but since then the eml came on, I then turned off the car, back on and it disappeared. Since, it comes on after about 10 minutes, haven't had long to look at it, not sure if it's coming on once it's up to temperature. Just wondering if there is anything to look for? Thanks
