FYI, I recently replaced the auxiliary air valve (AAV) on my 328 due to horrific cold start idling. At the same time I found and ordered a new frequency valve protection relay from Pelican Parts ($91.00) as part of preventative maintenance. OEM part number 92861512400 Cross reference part # 92861512402 The cross reference part is an exact replacement and has a flip plastic cover to add protection to the 10 amp fuse. I will add this part number to the parts reference sticky page.
