Ghost Immobiliser causing fault codes

[Saeedk1995]

Hi all,

I’ve got a Mercedes e400d 2019 saloon. Recently bought it and got an auto watch ghost 2 immobiliser fitted by a specialist who does them around Manchester.

Since then the car has been driving under powered, feels almost like a dpf block. However, there is no fault signs coming up on the dash. So I took it to a Mercedes Benz specialist for diagnoses. I put the ghost on service mode and then he used the Mercedes Benz software to check, he found a few fault codes related to ignition. P253300 in the SCR (my adblue levels are fine) and U0426FA in motor electronics.

I’ve sent the pictures of the codes to the person who fitted the ghost immobiliser. I’m not sure what to do really and I was seeking to some advice. Could it be from the ghost immobiliser? The car was running perfectly fine before that was installed. On the same day I also had front and rear dash cams hardwired in.

Has anyone had this sort of issue before? At this point I just want to take off the immobiliser.

It's possible that the installer has not done a good job on fitting the Ghost immobiliser but before blaming that, get the dashcam wiring checked too.
Is the guy who fitted the immobiliser an accredited Ghost installer?
If you were closer I'd suggest visiting Comandonline in Surrey who fitted my Ghost to have the installation checked over. Never had a moments problem with my Ghost.

It wouldn't be the first time they have piggybacked a fuse for a dashcam install. Seen it a few times.

they said they wired it to the passenger side fuse box. Would that affect the engine performance though? And cause fault codes related to ignition and SCR?

Thank you for the advice. Yeah im gonna ask the merc specialist to check the wiring. I’ve asked if the ghost Immobiliser fitter is accredited by Tassa, just waiting to hear back.

If you yank that fuse and prob goes away does that not illustrate origin of issue?
Assuming you have kit to clear codes.
