Frequently Asked Questions

What are the 'hotspots' on my Audi e-tron GT brake discs?

Hotspots and discoloration are visual changes that can appear on the friction surface of your Audi e-tron GT's tungsten carbide brake discs. These are typically caused by thermal stress during braking, especially under varying driving conditions. Audi TSB 2073824/2 confirms these are cosmetic and do not affect brake function.

Do these brake disc hotspots affect my vehicle's braking performance or safety?

No, according to Audi Technical Service Bulletin 2073824/2, the hotspots and discoloration on the tungsten carbide brake discs are purely visual and do not impair the function or safety of your vehicle's braking system. Workshop findings have confirmed that there are no abnormalities in brake disc axial run-out when these visual changes are present.

Will Audi cover the replacement of brake discs with hotspots under warranty?

Audi Technical Service Bulletin 2073824/2 explicitly states that replacement of parts due to this phenomenon is not justified. The TSB also warns that Audi may reject warranty claims for this cosmetic issue and charge back the cost of any parts replaced.
