flash22 154 Posted February 10 Have you had the codes read ? p Lock is usually a flat aux Battery - replace the Battery with same type only (AGM) You can check the 12v Battery voltage by putting the mfd into maintenance mode There is a work around by pulling a 7.5a fuse have a look on youtube 1 Quote Share this post Link to post Share on other sites

With what are you reading the codes? Sounds like whatever you are using can only read basic ECU and maybe ABS. There are about another 9 ECUs you are not seeing.

You need to look them up in the repair manual as they are quite involved in diagnosing. Quote Share this post Link to post Share on other sites
flash22 154 Posted February 13 I would be checking that 12V Aux Battery properly under load with a Battery tester, electronics do strange things with low voltage/current, its more than likely the original so 13+ years old Remember these codes are a symptom, not the fault Quote Share this post Link to post Share on other sites
kithmo 240 Posted February 13 First thing that came to my mind when you mentioned P-Lock is the parking pawl. Can you move the car when you take the manual (foot operated) parking brake off ? Quote Share this post Link to post Share on other sites
