1st post sorry if in wrong place.

I have a Mk1 Fabia classic 02 plate and really random problem but every time i drive on a certain bit of road near me the EML comes on and have to reset it to get rid of it and brings up a different fault code each time it happens. when i last got it back from garage i avoided this bit of road for approx 200miles to test my theory that it was that section of road which was a pain to do but  then took it back down said road a it came on instantly. Any ideas what would cause this or a way to fix? 

Is there anything noteworthy about this particular stretch of road? Lots of lumps and bumps? Potholes? Lots of slow tight bends? Steep up/downhill slopes? 

 

Do you have a record of any/all of the fault codes that have appeared?
