As an after thought, if the eka is related to vin number, I did some playing around with my VIN .
VIN divided by 4.5= X, X + 18 = EKA ( I did round off numbers after decimal point in X)
Coincidence? It would be interesting to find out how this fares with other forum users that already know the EKA for their cars. Any body up for some mathamatics?
It would be interesting how this works or not for other cars.
