Please please help if you can!
I am the proud owner of a very nice S80 2007 2.4 diesel. I've had the car for 3 years and it's been a joy. Sadly the last 6 months have been quite an expensive nightmare. When the car is cold and I get in it for the first time of the day it starts no problem. However, when I've driven for a while and, say, I fill it up with diesel or pop into a shop, she won't start again. I get the same notices on the speedo dial. "Immobiliser see manual, parking brake failure stop safely, and are airbag service urgent"!
I've taken it back to the dealers 3 times and so far I've had a new battery out in, which worked for a week. Then they spent 8 hours checking wires were all fine and connections weren't oxidised or loose. That lasted for about 3 days. And most recently I had a new CEM fitted. Those trips have now set me back £1000 and the problem came back again yesterday. I could've cried I was so gutted!
If there's anybody out there who knows something that might help please send me your opinion. The cars going back in on the 1st of July, but money has all but gone and I'm at my wits end with frustration. The car is a push button start and both keys give the same error warnings.
I hope to hear from some hero soon.
Many thanks and sorry for the long lost!

 

I would check PSCM connector.
PSCM = Power Steering Control Module.
If car is AWD also try to disconnect DEM connector.
DEM = Differential Electronic Module

 

Thank you. I'm more a driver than a mechanic so I wouldn't know where to even look for those or if I did, I wouldn't know if the were faulty or not. Have you experienced the same problem then? Anything I learn I'll be giving to the dealership guys to look into.
Thanks again for the reply mate.
