Audi I5 Turbo Engines - Stainless Steel Nuts and Bolts

Those struggling with the 28-year-old fasteners fitted to an early Audi ur-quattro might be forgiven for replacing every single nut and bolt with stainless steel versions to avoid the problems in the future.

Not always a good idea:

Some situations combine; the cam cover nuts never corrode and occasionally fall into an open bore through the spark plug hole - stainless is obviously a doubly bad idea. With that in mind, the following list has been assembled:
