2013 xc70 chaos after battery replacement
hi folks-decided to carry out a battery replacement as preventive maintainance-ahem really wish i hadnt....
changed battery for a bosch newbie-started car,reset windows which were about the only codes to come up on first scan Took out for a drive-instant limp mode,loads dash warnings and an armful of codes,coo codes[too many to mention,comms,algorithms etc]-so i cleared these and they keep coming back battery showing 12.4 v engine stopped 14.4 running[vida] its not a stop start so i didnt code battery in[if you can] any idea what has went wrong-loads strange things happen=idles at 1500 rpm,sometimes wont come out of p,tells you its not in p when it is also any idea what the wire is that goes from positive to negative terminal-its got a thin bit to blow in case of an accident or major short i should think-looks like it has been pinched in middle a bit-could this be relevant previous owner had issues with the car,but i havent,although there were a raft of faults logged when i bought vida they all cleared off and didnt return[except my faulty pam module] as usual any help welcome-it must have happened tosomebody else on here before lol |

procedure
i disconected earth first on removal to replace i connected positive first
This car has a history of failure scince end feb-it was fine with me until i removed battery The same fault codes stored were in the memory when i bought it,were easily erased then I seem to have been able to re-create the fault/s issues by changing battery The wire is covered in a black nylon sheath-this i removed to look at it [the sheath] and it starts off thick at positive-has a very very thin section in centre then goes to a plug on the block attached to negative terminal cant get a pic right now as not at car-its about the only fragile looking part where battery is-looks like it might be a fuse/ current spike wire designed to blow Last edited by tonys1966; May 11th, 2022 at 20:34. |

there is a procedure to follow when reconnecting battery key in position 2 its possible you may have spiked some of the electrical modules re scan with vida to check modules

vida
vida scans all the modules,clears the faults[except my faulty pam module and they all come back fairly quickly,i can drive the car maybe a mile...then it starts throwing all the warnings up
Strange unless its a duff bosch new battery-but it starts the car,shows 12,4 v and 14.4 once running |
