srs light help

I have 99 328i, that has the airbag light on because of the passenger selt belt pretensioner. I replaced the buckle, the took it back to local shop that did the first scan. this time They were only able scan engine codes but could not connect to srs system, no matter what tool they tried.

I was thinking of trying the Peake scanner, but i am concern that wont work either. Any suggestions?

The best would be to invest $30 or so towards BMW Scanner 1.4 (massive thread on this in the general e46 section). It can read/clear airbag codes, read/clear bmw specific fault codes and code the car for various things.

The buckle might not have been needed to be replaced, but this:


Verify on www.realoem.com using your vin on which is the correct part number.

Often times (dare I say most times?) you don't need to replace the entire $120 tensioner, just the $10 wiring for it

In order to access the srs module, you'll need to connect to the round port underneath the hood
