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.Дo 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.ДЄbout 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. Now wondering if I have an alternator fault.In response to your questions- my car is a 2017 VW Tiguan Mk 2 4WD 2.0L diesel. I thought it should show more if it's charging OK. Started OK and but voltage with it running is only 12.6v. Had the battery on charge yesterday for about six hours and it got up to around 13v. I can get a similar battery Varta F21 80AH at ВЈ150 or Varta G14 95AH which is slightly larger but will fit at ВЈ180 so there is a considerable saving if VCDS will work OK.

VW quoted ВЈ268 inc VAT for supply and fit new 95AH battery but don't seem to know the make. So as my question, has anyone successfully coded in a new battery or even checked the existing code? Currently I assume the exisiting battery is coded in OK as everything works on the van but according to the video I should be able to check the existing coding which I can't do. So, I can't use the drop down to get option 1. Into 61, 07 Coding and the drop down menu is greyed out showing option 0. Has anyone actually used VCDS to recode a new battery? I have just connected VCDS and gone through the stages shown in the video. The van has hardly been used this year and has spent most of it's time on hook up as the the other half has been using it as an office working from home. 2014 SE 4Motion and the starter battery isn't holdig a charge any more. Does anyone know of another App to work with the Carista dongle or a stand-alone system thatвЂ™s would do the job that is more cost effective than visiting a Dealership who would insist on supplying a new battery at VW prices? I have Carista and the app doesnвЂ™t seem to do it. If yes, is there a simple OBD tool on the market that can do this? Happy to change it as I use it a lot.Д«ut, if changing Like for Like do you have to recode the new battery? The vehicle was built July/August 2014 arrived at Dealers early September but not picked up until 1st December so more than likely sat in Dealers storage compound for some weeks/months with a flat/low voltage.ДЄnyway, I know others have older vehicles on the original battery, IвЂ™m not concerned mine has failed after 6 years. But, switching the radio on when engine off and the voltage drops quit quickly from 12.5 v to below 11.8 when my voltmeter alarm sounds. Twice over the past 2 weeks, after not being used for 24+ hrs, it was very sluggish turning over but did start.Д¬harging the engine battery was fine, no warning lights when driving, alternator output to both engine and leisure batteries fine on the move. Ok, my California is almost 6 yrs old and just shy of 100,000 miles.
