Record 6/16: Energy balances (last 10 trips) Record 5/16: Energy-critical vehicle states Record 1/16: No-load voltage underranging Component and/or Version: GW MQB High 128 1265 Control Module Part Number: 5Q0 907 530 AM UPDATE: Just measured battery standing voltage with a multimeter and it's 12.2V Engine running 14.8V The brakes have again been playing up and that is when I went into VCDS and it told me the battery was at 70% charge with a voltage of 12.0 shown at the end of my Autoscan.ĭo you know if it is possible to do some more involved testing of voltage levels- perhaps within the ABS controller? I then charged it for about 5 hours with the CTEK until it got to stage 7.
My latest theory relates to battery voltage and this is what I was looking into with VCDS.Ībout a month ago I measured the voltage across the battery with a multimeter and it read 12.4V
with the hope of finding an underlying cause. My dealer finds nothing on test and indeed- the car behaves when it goes in to be checked! I have had issues with the handbrake and auto hold not releasing on occasions- each episode lasting a week or so, with no apparent set of circumstances indicating a cause.
In response to your questions- my car is a 2017 VW Tiguan Mk 2 4WD 2.0L diesel.
