My experience was not a good one. I received several warning messages from my Volvo S80. Some online research suggested the cause was likely to be a defective central electronic module (CEM). I usually get my Volvo serviced at S&S Motors but they were temporarily closed as they relocated. I contacted Central Import and asked if they could service a CEM issue or if I needed to go to a dealer for that. They said that they needed to run diagnostics first, which I expected, but yes they could service CEM problems. I brought my car in, they ran diagnostics and confirmed the issue was with the CEM. Their option for repair was to remove it and send it out to be fixed. I asked how long that would take. They said they couldn't say as it depended on a 3rd party. I pressed for more info and they said that in the past it has taken up to 2 weeks. With the CEM removed the car couldn't be driven. Leaving the car with them for maybe 2 weeks and not even being certain it would be fixed was not a realistic option to offer a customer. I asked them to source a replacement for Volvo rather than repair the existing one. When I called back to check on that option they said that one could be ordered from Volvo but the installation required it to be coded to my car and they could not do that. That is why they like to repair the existing one as it does not need to be recoded. To me this really means that they can't service CEM problems. I felt they should have been more transparent about their limitations with this type of repair. Because they weren't forthcoming about their limited ability to help me I wasted a lot of time and spent $225 on diagnostics and got no value at all from it.
