jarvid Posted August 31, 2015 Share Posted August 31, 2015 I have a 2.0 Tddi and on two separate times apart by two weeks this warning light has come on, on long trips when I park up, lock the car up and return start up everything is ok. Is it water or is it the oil temp or any other ideas??? Quote Link to comment Share on other sites More sharing options...
Nadiamondeo87 Posted August 31, 2015 Share Posted August 31, 2015 I have the same thing. Very intermittent. 3 month gaps between mine. I managed to get into the computer on the screen to find some code, if you press and hold the ok button for a few secs then turn the ignition on while holding the button the car will do a gauge sweep and you can find the dtc fault codes in the list by pressing the ok button to flick through the tests.

jarvid Posted August 31, 2015 Author Share Posted August 31, 2015 Thanks Nadia, I did that it came up with two codes, any ides how i find out what the codes mean ??? DTC 01--- C40168 DCT 02--- C41668 Thanks again Quote Link to comment Share on other sites More sharing options...
Nadiamondeo87 Posted August 31, 2015 Share Posted August 31, 2015 Ahhhh no way! They're 2 of the codes I have on mine! I also have c42268 on my list. I suspect they're only sensor issues. They're not major fault codes though. And if you plug it into a normal diagnostic computer it won't list any faults. The only way we can find it out is to take it to Ford as they're not ecu faults, they're bcu faults which only Ford can translate - but I'm sure it comes with a hefty price tag. If it does the malfunction light again, keep the engine running and get the aa out as they can get the codes when they plug it in with the light on. That's my plan! Unless someone answers my post on here! Quote Link to comment Share on other sites More sharing options...
jarvid Posted August 31, 2015 Author Share Posted August 31, 2015 Thanks anyway, did`nt know i could get the codes myself. it was clever to watch it go through the checks and things. Quote Link to comment Share on other sites More sharing options...
Nadiamondeo87 Posted August 31, 2015 Share Posted August 31, 2015 Yeah definitely was. The led test looks like the starship enterprise! Haha Quote Link to comment Share on other sites More sharing options...
jarvid Posted September 2, 2015 Author Share Posted September 2, 2015 Hi Nadia, have news for you c codes relate to chassis code 1 c40168 - indicates no information being received from a control unit. code 2 c41668 - indicates missing ABS information.ie- wheel sensor, wheel ring or control unit. have also been told to try my cruse control as in could be faulty. nothing major unless abs light comes on and stays on.

Nadiamondeo87 Posted September 2, 2015 Share Posted September 2, 2015 Oh that's good news! How did you find it out? I reckon my 3rd code is the cruise control as when the light came on the cruise control was on, but the speed dropped. I could still accelerate myself fine though. 1 Quote Link to comment Share on other sites More sharing options...
jarvid Posted September 2, 2015 Author Share Posted September 2, 2015 A friend at work used to be a service manager, yours is probably going to be your wheel ring, Quote Link to comment Share on other sites More sharing options...
Nadiamondeo87 Posted September 2, 2015 Share Posted September 2, 2015 Brill.... At least I know where to get my mechanic to look! Gonna wait until it's service in about a month. Thanks for your help! Quote Link to comment Share on other sites More sharing options...
