Hello, what software you have used for the retrofit - p3tools or VDASH?
Also did you had the error before the retrofit?

@T5-T6-Schnappi Thank you for the advice! Why not to do the retrofit? Is there any risk for not functioning, or not working at all?

Hello again, just to check if someone can help...
Also I`m planning to install a TFT odometer (already have it, just the additional cable is the problem). Is that going to fix the error code and show the real mileage?

Hello,

I`m constantly receiving the DIM-U300045 error code considering that my mileage has been manipulated, as I have checked with CarVertical and it appeared that around 50K km "dissapeared" in my calculations. Is there a way to fix that, what will be the price for it, and will the odometer show the real mileage after the fix?
Thank you in advance!
