3 series 330D Airbag problem

[Callrova]

Hi chaps. I'm pulling my hair out with this airbag problem i'm working on for my elderly neighbour.

I'm Using Snapon Verus.  it's a 2004 330D estate.  Fault code  03, ignition Circuit ZK2 Belt tensioner Passenger. I've replaced the pre tensioner but the fault will not clear. 

Anyone with any sharable knowledge regarding this?  I'm looking at a faulty SRS module.

Any help would be so appreciated.

Morning Richard

Welcome to the Forum

First is the replacement "new" or second hand worth testing it, next I would check continuity on the loom to the SRS module before changing the actual Module 

Don't know why but passenger seat occupancy was also an issue worth checking the sensor mat

Hope this helps

Hi Dave,

Thank you for replying.

I've gone through all that. Tested the pre tensioner, sits on 0.06. Done the continuity's, fuses, everything is hanging loose in the car, fusebox etc.

Can the SRS module be swapped over on this model year? & fault cleared or do they have to be cloned?

Hi Richard

As long as it is the same Part Number you should be OK, worst case scenario it will need registering to the chassis. While BMW Dealers try and make a big deal of it it is simple and straight forward. Normally if your Snapon tool will recognise the Module it's just entering the Vin sometimes just the last 7 digits is enough.

If not try BMW 1.4.0 you can get it for between £10 and £20 depending where you buy it will give you dealer level access to all BMW's up to 2006/2007

Thank you Dave, That's a great piece of info. Absolutely appreciate it. 

I work with Land Rovers/ Range Rovers hacking & cloning, unlocking etc, although the P38's & early L322's were mostly BMW.

Looks like I'll try & replace the module like for like next.
