Thank you

Year, engine, mileage, history, code descriptions ??
If those hard faults are pointing to the ABS module and you checked the basics then the problem could the ABS module itself.

Year of car - 2004
Diesel Automatic
Mileage around 180k


Hope that helps ?

Transfer case communication failure

Dead glow plug

EGR fault

EGR fault

Is the transfer case (VTG) unplugged? :dunno:

Regarding the EGR fault. I have blanked the EGR valve so there is nothing coming in from the exhaust manifold.


I will check the glow plugs tomorrow to see what can be fixed there.

On the transfere case communication. What does that imply? I have checked the actuator motor previously and the gears were in good condition.
I will try to have a look tomorrow on the car and see if there is anything obvious that is fixable, like a loose connection etc.

Thank you

The code is for the controller unit, which is mounted on the block below the intake manifold...

Thank you, i will check later.


As regards the glow plugs. I think mine may be the original plugs and my car has done about 180k.

How long should the plugs last for and is it wise to change the controller unit at the same time as changing the plugs?


Thanks

By 200k kms I had four glow plugs errors and since the controller module is known to fail, as well as the glow plugs, I replaced all six glow plugs and the module at the same time.

At 280k kms I now have a single glow plug error (cylinder #1) but I think that it's a connection issue - seems to be intermittent.

At 180k, if you are in there, I'd replace all glow plugs and the controller.

Yes, that does make sense to do all 6 and the controller too.
It has to be done sooner than later, especially as it is getting colder now.


When it comes to glow plugs what is the better brand to go for? I know on ebay you can get 6 plugs for £25 and the most expensive (Bosch) plugs are around £60.00.
What would you go for ?



Thanks

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
