This is what the dealership said
--FILL PLUG FOR HALDEX IS LOOSE. UPON REMOVING FOUND THREADS HAVE BEEN PULLED FROM A PRIOR SERVICE. WILL REQUIRE REPLACEMENT OF REAR DIFFERENTIAL DUE TO FILL PLUG NOT BEING ABLE TO BE TORQUED.
Is there a cheaper way to fix this?
I have a 2012 Tiguan RHD. My dealer told me that I needed a new Haldex Clutch and Rear Differential at 11,000 miles. Instead of ordering one from Germany they decided to take one off a car in the showroom and put it on my car.
2 Days later the car locked up and lost control and my daughter ran...
