Grant 4 Report post Posted November 8, 2005 Yes, you should be able to read it once you remove the panel below the steering wheel (the big one that the pedals go through, and that hides the steering column). With a torch, you should be able to read then number off the ECU casing easily enough. Failing that you should be able to take the ECU out, get the number and put it back in within 5 minutes.
