Hi all,

I have a 2008 2.0 TDCI, which I purchased just under 3 months ago.

Over the last few weeks, on a couple of occasions, it has thrown an Engine Malfunction and gone into limp mode with the ESP light illuminated. Reading the code in test mode, it has a C41668 in DTC01, no other codes are present. Restarting the engine clears the malfunction, and the cars seems fine again.

I've not been able to find much information about this code, but from what I can gather:

C41668 = U0416-68

U0416 = Invalid Data Received From Vehicle Dynamics Control Module

68 = DTC Failure Subtype Definition for failure Category "6". Event information - This subtype is Used by the Control module to Indicate the Detection of a System That event caused by WAS Not the Control module Itself BUT Forces the Control module to store a DTC (EG Functionality missing from Another System / Control module).

I'm not completely sure what this means, but more importantly, I'm not sure what the resolution would be.

Can anyone offer any insight please?

Thanks,

Lee

Did you ever find out the problem? Hehe. Got the same problem with the same car. 

You expect an answer from a "One Post Wonder" who hasn't been on the forum in 13 years ? 🤣😂🤣😂

Welcome @Setzer you are obviously seeking a solution to your problem which no one on here posted when the OPW asked all those years ago - a regular and disappointing ocurrence from both points of view?

I'm unsure about the C code and if it was read with Forscan (our recommended software with lead) as this MAY provide more information. 

Perhaps something to do with ABS sensors as maybe a likely cause, otherwise a more complex issue - total guess?
