Hi Jon, I've got a situation as follows with my 2006 S60 2.5T. I'm baffled by the problem and wondered if you had any thoughts on it.Hey everybody!
My name is Jon and I'm a certified Volvo tech in Pittsburgh Pa.
If anyone has a question about their Volvo, please ask!
While driving, my 2006 S60 2.5 T repeatedly acts like it is going to die, and it has actually died on one occasion while gently accelerating from a stop light. The check engine light has come on three times now. When it came on the the first time I took the car to a general mechanic (NOT a Volvo service department or a private mechanic who specializes in Volvo mechanical repair). The mechanic hooked the car up to his computer and received numerous "low voltage" and "grounding" error codes for a variety of systems, including tail lights and fuel system.
The mechanic cleared the codes and said to bring the car back if the check engine light came back on. The car continued to periodically acts as if it was going to die and for some strange reason it usually occurs while accelerating away from stop signs and stop lights. The check engine light came back on several days after it was initially checked out by the general mechanic. Unfortunately, the check engine light went out on its own within one day of coming back on and before I could get the car back to the mechanic. The check engine came back on today under normal driving conditions. It was acting like it was going to die again as I accelerated gently away from several stop lights. The check engine came back on today when the car was not acting up.
I'm wondering if anyone has thoughts on what could be causing this problem. I also suspect that the non-Volvo diagnostic database that was used by the mechanic may different and reflect non specific codes that are different than the Volvo diagnostic computer database would show? Any thoughts and input from experts would be greatly appreciated. As a side note, just in case its relevant, the vehicle has nearly 198,000 miles on it but it not driven hard and has been meticulously maintained.
Thank you in advance for any and all help that anyone can provide.
