I have a 330d LCI with the N57 engine.

As I have the N57; INPA can't give specifics on the fault codes.

I have the following which I believe are due to my Combox retrofit:
KOMBI A554 60
MASK/CCC E1CF 20

The first I believe is due the fact that the SOS feature now doesn't work. My research on the second looks like a change of configuration to the original specification.

I then have:

JBBF A6D1 21 which I believe is an auxiliary water pump issue.
JBBF A6CF 68 which is an AUC sensor fault.

Finally I have DME/DDE 494A 61 which I believe is a glow plug fault.

My thoughts are I can cure the top two with some sort of coding, the water pump issue I'm not sure, I can buy an AUC sensor for not much and the DDE issue maybe a glow pug control unit.

Thoughts?

I had the same fault with my aux water pump. I bought a s/h one from a breakers for £30. I fitted it in about 30 minutes by clamping the inlet and outlet coolant pipes before removing the pump. No issues since.

Cracking. Thanks.
So the code was resolved after fitting the new part?
I've read that the carbon bushes wear which causes the issue.

Yes - the code disappeared immediately. I tried dismantling the original pump initially to see if I could see what was causing the fault but when I realised that the fault was pretty rare and I could get a S/H one for £30 I took the easy option.

Cracking. I take it this is what you picked up?

Yes - thats the part. Just check on REALOEM that the part number is the same as that needed for your vehicle. These pumps have been used on numerous models but the inlet and outlet pipe layout can vary.

Hi guys,

Any feedback on the JBBF A6CF error? I have the same on my E92 2007 N54 335i... Is this related to the auxilary water pump?

The AC6F fault is the AUC sensor which is the air quality sensor under the bonnet. I bought a second hand one on eBay about 4 years ago for £20 and all is well.
