Volvo XC70 Check Engine & Electrical Issues
1) Check engine light is on, and says that service is required. I took it to Auto Zone, and they came up with the code 2112. Auto Zone does not have codes that correspond that high, and the dealer claims that they have different readers which show different codes than at Auto Zone. Is this true? Does anyone have an idea about what this problem might be?
2) Electrical systems seems to be very quirky... I would say 3-5 times per week, I find my alarm system going off for no reason. Also, periodically, the sunroof decides not to work. Have others experienced similar issues, and if so, how did you correct them? I am afraid that the costs to repair will be significant, and not worth it, since they are more of a nuisance than a real problem (or at least I believe this to be true).
Thanks in advance for your help!
