Volkswagen South Africa should not be trusted

I am really disappointed in Volkswagen SA. I have bought 3 VW's since 2007. Currently, the Polo we bought in 2017 is under the VAP Maintenance plan until 2027.

We had a problem and McCarthy VW Durban diagnosed this as being the spark plug failure. We were told that this was caused by the fuel having too much metals in the car and therefore Volkswage SA will not be paying for the parts and labour. I was told that there has been a lot of VW's that have come in to dealerships for the same issue and Volkswagen SA is not honouring the maintenance plan for the spark plugs.

That is really pathetic.

Firstly, the vehicles have valid maintenance plan and Volkswagen SA is not honouring this agreement.

Secondly, how are we as owners supposed to know fuel is going to cause this and if this is the case then surely Volkswagen SA must pay the claim per the maintenance plan and then lodge a claim with the Fuel association, as insurance companies do by claiming back from the 3rd party insurance company where the 3rd party is responsible for damages.

Thirdly, if the fuel is causing this issue why are other vehicles (not VW's) also having the same problem? Surely the spark plugs fitted on the VW's clearly have a problem.

Lastly, I only fill at one garage and can prove this so if Volkswagen SA wants to only claim from that one fuel company they will have proof of the fuel supp**** to my car.

This is really disgraceful by Volkswagen SA.
