Volvo V70 II P26 Built 2001, model year 2002 2.4l 140 hp petrol engine type: B5244S2 Hello, I’ve been through some posts and threads now and I hope for help or good advice from you… Basically I have 2 points, where I don’t know exactly whether they are related or not, therefore summarized in a thread. 2. Engine system maintenance required Since the vehicle is (almost) in possession, the error message is displayed sporadicly in the on-board computer. Sometimes a door is open open/close, and the message is no longer displayed. I’ve already read the wildest things about it but I didn’t get smart about it. Basically, I find that nothing is in the memory. The error memory has been read with VIDA several times, currently I don’t have the software anymore, but also with other Diag. nothing gets out of it.
