- Code: 004DFB
<===========================>
1. ABS / DSC / Brake:
<--------------------------->
Dynamische Stabilitaets Kontrolle / DSC:

<===========================>

Cheers,

You've got a dicky left rear wheel speed sensor or potentially a swollen reluctor ring.

That will fix faults 1, 3 & 4.

No 2 looks like the High Pressure Fuel Pump;

Thanks mate.

I REALLY hope it's not the HPFP. Saying that, the car is a little lumpy for a few mins on startup.
Is that normal for the N57 diesel lumps?

Speed sensor is a cheap and easy fix so will get that sorted and then scan the car again.

On the first scan, the 4DFB code didn't show up...

Forgot to add, my cars a 325d LCI.

I have a 330d LCI with the N57 and its smooth as silk on idle.

It was lumpy on idle when I bought it but that was 4 dead glow plugs but you don't have codes for glow plug faults.

Still a tiny bit lumpy this morning but only on initial start up. I can drive 20 yards and stop and it's fine?

The 4DFB code didn't pop up today but the other speed sensor related ones did.

What diagnostic tool are you using?

I'd suggest getting a copy of Rheingold if you don't already have it as it can do some clever stuff. There may be options to reset the fuel pump etc.

I'm using a Carly Gen 2 module.

I don't think that'll be advanced enough for what you need Buddy.

Get a K+D-Can cable and this will get you a working version of Rheingold.

Google rutracker Rheingold 3.47.10. That is a fully working version of the software. There are newer versions but they require an earlier version such as this to install.

To install; Google car technology 3.44 and firstly follow the instructions on here to install. Then use the instructions in the configuration manual that came with the download to finish it off.

It sounds complex but it's pretty straightforward if you follow the instructions step by step.

Will look into this if the HPFP error shows its head again...

Thanks mate for the info.
