Thanks for the response. I had an extra bit of curiosity because I'm actually a Service Advisor for a very high volume Volvo dealership. The way they approached your situation was all wrong. They should have told you that it was leaking and they will inspect the internals upon disassembly. Sometimes just the exterior seals can be replaced but sometimes the unit actually needs to be removed and disassembled to reseal the two case halves, as I suspect was your case. On the west coast of the US, complete case reseal runs about $850 + tax, exterior seals (without disassembly) about $375 + tax. I'm glad your situation sounds like it worked out well. The Service Advisor that you were working with could really use some training. Thanks for your feedback and time, R.
