I’m very sorry to hear of the issues you are having with your car.  And the difficulties getting it sorted under warranty. 
 

Is the car still covered by the original factory warranty?  Or is it a dealership used car warranty?  Not sure what type of Golf yours or its age. 

 

Have they carried out an overnight test on the battery?   
 

Don’t take this the wrong way but I think you need to get more assertive with them and ask for details of the warranty.   If the battery is covered under warranty (if it’s the factory warranty it should be) then they should replace it and should reimburse the cost of the diagnostics you’ve paid out for. 
 

I had issues with the battery on my mk8R (when it was less than a year old) and that was covered under the original factory warranty and replaced no issues.  And the same with my mk7R battery which kept losing charge and wouldn’t hold charge - that was tested and replaced under warranty.  I did not have to pay out for diagnostics in either case. 

 

Hi guys bit of an update on my mk8.5 Battery 

So VW GARAGE had my car for “two day investigation” which to my findings they only worked on the car about 3h ish out of what they call two day’s investigation ! after all this they said that battery is healthy and it’s not going to be covered by warranty. I’m not sure I’m saying this correctly but they said battery showing “0.1A” which means battery is good , they said if it was 0.3A would not be good. They also would not give me any print out of what was checked or done in this so called two days investigation. They kept telling me they not allowed to disclose any information. They literally showed me few things on paper but wasn’t allowed to take copy or screenshots. How is this even right not to give out to customers checks done while they had the car ! 

I did some checks with multimeter again to see if you guys make sense of it and if this is ok for my battery or is the battery to low. I’m not an expert just trying to figure out if or not this battery is ok or not. For the record the car starts fine and runs fine. But the question remains have VW done the right checks or they just play around telling me battery is health ?they have Checked my car on 3 occasions now. If battery is fine and all ok “ why did they tell me they have to do a two day investigation with VW Technician “

Surely that means the parasitic draw when the car is fully asleep not actual amps otherwise its dead.

 I don’t know sorry I’m trying to explain it best way I can from what I was told because I have no paperwork showing what they checked and did !
