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

On the more technical code readers it should be able to read historic codes. As the car should store them once they appear even if the car has managed to find a way around the problem. I'd still be getting it checked if it were mine.
