Hello, with my V70 T6 first registration 10/2007 KM Stand 38000 this message comes for some time. “On call maintenance required”. I can push away, but comes again with every restart. According to my dealer, after diagnosis via OBD and computer through the plant the external battery is broken. A new such long-term battery costs allegedly 250.—€ plus mounting. This should be hard to access behind the glove compartment installed. Just like this hidden mounted wur I can still talk about the emergency call button with Volvo Köln. Go over the normal car battery. In case of a serious accident the very good emergency call system is no longer available, since then the normal car battery is immediately separated from the on-board grid and the intended power supply is gone. I have already had 4 times total failure of the car battery in the last 2 years and got 3 new ones, 2 on culancy of the workshop. I was even called by Volvo Köln once that my V70 was reported as stolen by the system, but was then again only an absolute car battery collapsed. Every time everything was measured on “spirit consumers” without finding out. Also the alternator is fine. Is the V70 only designed for frequent drivers? I still have a warranty extension until 10.10.12, but this battery is not supposed to be ert. Would look forward to receiving answers. Greetings Günter
