Engine malfunction detected
Q I have owned my 2010 Ford Galaxy 2.0 TDCi for a few months now. It has now covered 113,000 miles and has a full service history. Soon after buying it, I noticed that when accelerating hard (foot to floor in higher gears only – 4th/5th/6th) it will quite often display in the cluster the message “Engine malfunction detected” and the yellow information symbol above will illuminate.
The main EML does not illuminate and the engine continues to run absolutely fine with no loss of power. As soon as the ignition is switched-off, the warnings disappear as it does when driving if I just press ‘OK’ to the information.
In the “hidden” menu for the cluster, the DTC appears as C41668.
Checks online suggest it’s not an issue and it’s just the module picking up a ‘blip’ and so it lists this code as its picked-up something but doesn’t really know what!
A couple of months back, I got the garage I use to renew the oil/ filter and fuel filter and to check the codes with their plug-in reader.
The codes they found were:
U0415/416 invalid data received from ABS control module.
B1D01 Offside beam fault.
B1A69 Humidity sensor aircon.
None of these would explain why the message appears in cluster under hard acceleration. The garage didn’t seem concerned with these codes and just cleared them.
The aircon was vacuum tested, inject oil and recharged and seems to work fine.
I could just ignore the ‘C41668’ message but it must mean something but my issue
