E320 fault code 26
The check engine light came on after pulling out from the gas station. I ckecked the gas cap, it looks tight. I checked the fault codes by counting the LED flashes. The first time it counts 5, the second time 26. If I do it again it repeats, 5 and 26.
I replaced the OVP about a month ago. Does anyone have the codes? Does anyone know how to build a diagnostic tool for the E320 computer?
