My OE glow plugs were Beru but I used Bosch replacements. I used the Beru GSE102 controller but I see that is difficult to locate as an OEM part now.

Be aware that this engine (the M57TU aka M57N) uses 5v glow plugs, not the 12v ones used on the earlier M57.

Hi there

Thank you for your reply.

I have ordered new bosch glow plugs and a new Hitachi control unit for the glow plugs.

Looking at my VIN number i can see that my engine is M57D30TU or M57N and the voltage is 5V.


I am excited t get the work done as it is getting colder here in the UK, so need a perfect working car.


Thank you

The errors indicate a steering angle sensor fault (104) and time limitation passive switching (90) - so it could be two things but tackle the steering angle sensor first - the other error may be a symptom of that.

I used INPA to read some codes of my car.


The following codes are showing up on my car:-


5F1E - DSC Module

5EB0 - Steering wheel sensor

5F39 - Transfere case motor

5DCE - ???

5F42 - Limp mode ..??


So, i have a new transfere case motor that will be installed tomorrow as well as new glow plugs and the glow plug controller unit.


As regards the Steering wheel sensor i have ordered new brushes that i will try to replace on the unit.


I need to know where the DSC module is so i can have a look at that and replace it if i need to.


I will update once i have installed most of the things listed above.

Thanks
