Car running fine. Filled up w/ 11 gal. gas and when started "check engine" light came on and stayed on. Car appears to run OK. Checked for codes and got 2-3-2 and 1-3-1 in that order. Couldn't find info in Bentley for meaning of these codes when check engine light remains on. Any idea what's indicated? Thanks. Bill Stehlin

Hi Bill,
I got this from;
formatting link
These are for the Bosch LH2.4 Fuel Injection System, so I hope it's of some value to you and your 240.
Code 2-3-2 = Fuel trim (Lambda control) too lean or too rich at idle. If too rich: high fuel press., leaking injector. Symptoms - Idling problems.
Code 1-3-1= Ignition System RPM signal missing on starting. Wiring Fault or RPM sensor bad. Symptoms - Engine will not start................(Obviously this does not add up in your case.)
Good Luck. Andy I.
