Definitely on my 2002 2.5 CRD I get codes as follows:
Turn on ignition but do not start the engine.
Turn off quickly
Turn on quickly
Repeat this until you have turned it on 5 times....leave it on and read off the codes on the Odometer strip; the oldest code shows first with the most recent code showing last.
I have just tested it in my Jeep now....definitely 5 ON turns...very fast.!(I always thought it was 4 times?)
Does not always work....you have to retry to get it work eventually!
You can check that the guages move and all panel lights are operative by:
Hold down the Odometer reset button while turning on the ignition...the gauges move up and down and all panel lights come on.
Once you have some codes you have a chance of finding the fault!
I wonder if the fuel you put in is good!
