bsi unit exchange

[gibson24600]

Hi guys n gals, can I change my bsi unit for 2 nd hand one if I get the key that matches ?
My seat belt alarm still goes off even when seat belt connected, also window wipers cause alarm to go on/off intermittently, cheers for any help
Regards,
Hugh gibson.

Maybe you need a BSI reset,, this can be done but i'm not exactly sure how

What is the BSI guys the ECU?

[joemc20]

No V6,, BSI is the onboard computer housed underneath the passanger fusebox,, The ECU is engine control unit housed behind the battery

Tried reboot, no joy and my bsi unit is on drivers side under and to right of steering wheel....2003 1.9 hdi

[joemc20]

i believe relays are built into BSI and cant be replaced,, but if it helps my 2002 1.9 has them disabled and works fine,, check it out,, some one else told me not to get 2nd hand BSI as they only have problems too.. i got a diagnostics check done this morning and all that came up was the mass air flow sensor,, was heavy on diesel and was told to change filter and clean sensor with contacts spray,, not to touch,,, hopefully it will help

seatbelt alarms disabled i mean

If you replace the BSI with a used one, you will need to change the engine ECU & key set as well if it is a hdi version, all must be off the same vehicle.
If the car is a 1.9, then the job is more tricky.

Hi lighty, that's what I was led to believe, so that's a no no.
Joemc20, did you disable yourself or get in done in a garage ? My problem is because I live in france, tbey want to change bsi unit, 300 plus euro ! And I had hoped to be able to cancel or disable the alarm myself, or even tape over the little speaker lol, if I could find it......where is it ?

[joemc20]

Gibson,, not quite sure as i bought van 4 weeks ago and was disabled when i purchased,,, mine is a 1.9 diesel 2002,, but if there is anything i can help with just ask me as i can have a root around to see how they did it
