ive got a 2000 s80 t6 and 5 days ago i had a cylinder miss fire. i brought it to a trusted volvo shop and they replaced the one bad coil and all 6 plugs, i drove the car home that day and ididnt drive it till the next night. wheni turned the key, the starter was making noise but the car wasnt firing up. i then got the 'imobilizer' message and went to use my other key. once again it wasnt starting and so i tryed 2 more times and i got a new message: STC service required. i tryedstarting it one more time and i got: ABS brake service required.could it be that both keys need to get reprogrammed or did the shop do something to cause this? i cant figure this out and any information on what is going on would be greatly appreciated.

Thanks.

 

Sounds like the battery voltage might be to low.
By the clicking you heard and the messages sounds like low battery voltage the batterymight have gone bad.

 

I replaced the battery and it still wont fire up. but at least now i only have the imobilizer message for both keys.

 

i also noticed that everytime i tryed to start my car i was blowing an igniton coil fuse. maybe when the shop repaired my one ignition coil and my 6 plugs they put a faulty plug in or a bad coil?

 

Maybe they pinched a wire putting the cover back on.
