Hi everyone,

I took my 2008 v50 1.8 to the dealership for a software update in an effort to remedy an idle issue I have when the engine is warm.

The software update didn't help but they gave me a printout of some trouble codes. Can anyone help me identify what they might point to?

I have the following active codes:

CEM-DE01: Communication with BCM control module Signal missing

CEM-DF11: CAN-H, high speed network signal missing

DIM-0001: Mileage Manipulated

EPS-0081: Vehicle speed faulty signal

Am I right in thinking that the EPS module receives vehicle speed information from the BCM module? Does this signal go via the CEM? Is the missing CAN signal this missing signal?

There are no codes referring to the individual wheel speed sensors so is it safe to assume that I can rule out these?

Any and all help greatly appreciated.
