  • Alarm goes off unexpectedly

    Anyone seen this problem? Twice in the last week the Skoda Superb has had the alarm activated.. Flashing lights, sounds, the whole nine yards. Problem is it is locked in our garage and very safe. To top it off, this has happened at 0300 and 0430.... great way to get woken up.

    Any Suggestions, Dodgy Sensor??? etc

    Thanks

        Most alarms will have a beep code that will tell you what sensor has triggered. This is heard when you deactivate the triggered event.

        On my Hiace, it was the bonnet sensor that was the culprit. It was installed at such an angle that when the temperature dropped, the pnunger would shrink enough to set the switch.

                No worries. I don't suppose when they swapped the battery they tested to see how many amps your car is draining when OFF? I know some VAG cars have issues with battery draining caused from an issue with the CAN-BUS as well as accessories fitted to the car. It might be something that has contributed to the death of your battery.

                    It's an '09, probably '08-built car, so it was probably due for a battery anyways.

                    But you are right though, there are CAN-bus issues out there that do cause the same symptoms of flat batteries. Most of these will draw enough current to flatten it overnight, and continue to do it until the fault is rectified.

                        do you know the oil capacity for my car? I believe its 4.5 litres ? Can you confirm that?

                          Interesting info - and likely the reason why my car used to run the battery flat (or near flat) when i didn't drive it for 7-10 days......my P3 gauge which plugs into the OBD-II port must have been slowly draining power.

                            Press the lock button twice (which will disarm the interior motion sensors) and see if this stops your alarm going off. My Mk6 Golf used to do the same thing (and always at 2am of course) even though the car was all closed up and in my carport.

                              I think its about 4.3L or thereabouts in the 1.8 and 2.0 TSI engines - your owners manual will confirm. I always have around 0.5L left from a 5L container after doing an oil change.
