Car (South Africa) - - CONTENTS -

I bought a brand-new Volk­swa­gen Tiguan in Jan­uary 2017. In March of this year, a friend pointed out rust on the brake discs. I sent some pic­tures to the dealer, who told me it would dis­ap­pear with driv­ing.

I was un­happy with this an­swer, so l took the ve­hi­cle in to the dealer. A per­son from the work­shop gave it one look and told me he would phone the fac­tory. They came back to me and said it is only sur­face rust and they would not do any­thing about it. Volk­swa­gen South Africa is of the same opin­ion.

Ac­cord­ing to VWSA, a disc re­place­ment is the only fix but it will be for my ac­count be­cause the rust is not deemed a safety risk. I am not happy as I live in Dur­banville, which is not along­side the ocean and the car is garaged overnight. What are my op­tions? HANNELIZE COET­ZEE Dur­banville

Volk­swa­gen is cor­rect that the rust does not af­fect the op­er­a­tion of the disc and it should re­main safe in the fu­ture, as it is only sur­face rust. When a ve­hi­cle is parked for some time, the en­tire disc starts to rust and the ro­tor usu­ally gets “cleaned” only when the ve­hi­cle is driven again and the brakes are used.

How­ever, in the case of your Tiguan, brak­ing will not re­move the rust spots be­cause the pads do not cover the spe­cific area shown in the pic­tures you sent to us.

Dur­banville’s cli­mate is not se­verely cor­ro­sive (as, for ex­am­ple, Dur­ban’s is), so we are sur­prised by the lack of cor­ro­sive pro­tec­tion. But there is some­thing you can do. Ask the deal­er­ship to re­move the discs and pol­ish out the rust spots. Then tape up the discs so that only the in­ner hub ar­eas where the rust oc­curs are vis­i­ble. Care­fully spray the items with a clear lac­quer for­mu­lated for use on me­tal (a spray can is suit­able). This in­vis­i­ble layer pre­vents oxy­gen from com­ing in con­tact with the me­tal and pre­vents rust from form­ing.
