Hello I have a 1990 240dl with LH 3.1 and a 5 speed M47.I was wondering what the correct number ICU is for this car.I have a 572 ECU in there now and it's giving me a code 131 for engine rpm signal missing.I have changed the crank sensor and the CEL came back on.As this is an newer LH system timing cannot be adjusted,so the only components that read engine rpm are the crank sensor and the power stage amplifier which I think I would know if that was bad because the car wouldn't run.I have found many ECU interchange lists but none for ICUs so if you know the right number ICU that should go in a 3.1 car or if u have a 3.1 car that doesn't have a 131 code let me know your part number on your ICU
