Hy,
in the scoreboard of my ek sometime (most time in bumps) porter light blink. I think the problem is a bad contact with the sensor.

Can someone say me where is this senor or what can i do to solve it?

Thank you and excuse my bad english.

 

By porter light, do you mean CEL?

 

i want to say the back door

 

if its the hatch/trunk then its possible that its a bad contact, or that there is excessive play in how far the hatch/trunk can open in the latched position.
