Hi. Thanks for letting me join this site. I own a 2011 2.0 TD Q5 and whilst driving a week or so ago I noticed the coil light flashing on the dashboard and the car went into limp mode.After getting the car home, I restarted the engine and the coil light was not longer lit and the car was no longer in limp mode BUT the eml was on. I used a portable fault code reader that I own and the above faults were registered (P0403 and P0405). A few days later the eml light turned off but then a day or so later the coil light was on again and the car was in limp mode again. Again this went out on a restart but now I have no lights on and I have driven for approx 3 or 4 days and the lights are still not on. So my question really is can these type of faults repair or fix themselves, I have booked my car into a diesel specialist garage at the end of the week that I use but if the light remains off I will be cancelling? Any advise, thoughts or comments appreciated. Many Thanks
