Hey there, 04 jetta wagon gas engine, on my 4th set of front rotors in past year. All done at vw shop, they took apart and cleaned up back's, switched to certified VW rotors, completely tested and confirmed everything in front is working good. They can't understand what is causing the warping and now are telling me that next step would be to replace brake booster ($600) with no guarantee it will solve problem. Anybody experience anything similar or have thoughts? No uneducated speculation please, looking for some sound advice or similar experiences.
Thx for your time

look into new lines and calipers, a refresh of hardware can clear up problems like this also

Try increasing the air flow around the brakes by running ducting from front bumper
