Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Hi I have a 2002 Boxster S that is maybe worth £2500-£3000 but it failed MOT and now that I've sent it to a Porsche specialist they say the main MOT failure (airbag warning light) is caused by a failure in the airbag ECU.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi I have a 2002 Boxster S that is maybe worth £2500-£3000 but it failed MOT and now that I've sent it to a Porsche specialist they say the main MOT failure (airbag warning light) is caused by a failure in the airbag ECU. The part alone is something like £1400 which is half the value of the car (not to mention labour and other cosmetic issues that may need fixing). So what would you do? Is it worth the investment to repair? alternatively what do you think a 130,000 mile 2002 Boxster S is worth in MOT failed state ? Any advice gratefully received! Picture is car in 2020

POST 2Original post

A quick look on ebay reveals these units 996 618 219 00 for $50US. Supposedly in working condition.

POST 3Original post

Yes it is worth fixing IMHO. You have to realize it is now over 20 years old and things are going to fail, if you are not comfortable with that, then you should probably sell it. From the picture it looks to be in good shape but deferred maintenance can get expensive. If you do some of the maintenance yourself, the cost is more reasonable. There are lots of resources around including this forum that can help.

POST 4Original post

A lot of code readers will turn out that light. My Autel does, gave about 100 USD for it? David

POST 5Original post

My airbag light came on because of a failure of the passenger seat buckle. My Durametric helped me diagnose the issue.
