940 Immobiliser fitted?

Just because the spec says it has, does not mean that it has all the equipment fitted. The lefthand speaker device should be a sunlight sensor for the air conditioning. There is a version having the immobiliser only which does not need the alarm system as it is in place of the alarm. The "Glass breaking sensor" could well be the aerial for the immobiliser. The Remote Central Locking is tied into the immobiliser circuit and the diagnostic code for immobiliser is read on pin 3 of the diagnostic plug. You need a fob for the central locking's remote function. The trader must supply the key fob for the car and make sure that it matches correctly. Otherwise get the dealer to supply/fit and make sure that it works and get the trader to reimburse the dealer's bill. If the trader won't agree to this, get your money back and get a car that works fully (preferably with alarm fitted not immobiliser).

All the best, Peter.

Thanks for the info, the car was sold 'as is' ie clearly stated without alarm so I can't complain too much about that. Volvo will sort it out for around £80, although we will track down the previous owner hopefully.

However there are more serious problem now with oil loss then oil light comming on after a head-degunk and oil change. I think the sale of goods act should cover it, and they should be protected for this problem even when selling under as is, since it wasn't sold for further repair or parts. See seperate post.
