I have been having the EEP1 coming up in the mileage screen of my Z3 1,9 2002. It started to happen about a year ago, when the car was cold in the garage it would show EEP1 but if left outside in the sunshine for a short while the mileage would show correctly. This has been getting steadily worse and as I need to sell the car needed it sorting out.
Read lots of posts on this forum and others but the only way it seemed to sort was having a new or second hand instrument cluster and a lot of fiddling to get it sorted along with a tamper dot.
I took the instrument cluster off the car (other posts on how to do this) and removed the face from the back board (5 screws) It seemed that the coding chip on the back may be the problem so cleaned this and put back in the car, still the same. I then found that if I warmed the right hand side of the circuit board with a hairdryer (very gently) the EEP1 issue went but returned back when cooled down. My reasoning is that either a dry solder joint or a damaged track on the board is causing the issue and not a coding plug issue. I looked closely at both but could find no visible signs of dry solder or cracked track.
One of the post on this form mentioned a company called Autotronics. Having spoken to half a dozen other 'instrument repair' specialists who were not very helpful to say the least or just not interested. Autotronics had not come across this issue but were will to investigate on a no solve no charge basis. Sent the instrument cluster to them using their DHL collection and return. 4 days later I now have a working instrument cluster with no EEP1 showing and all working as it should. It appears that I have a new (second hand) cluster but for the total cost of £160 I am now happy that the issue is sorted.
I have no affiliation with Autotronics just pleased they sorted the problem.
Hope this helps with anyone else with this issue.
