I picked up an 05.5 A4 that was't running and it ended up being a broken timing chain but when I removed the rear cover I found the head of the cam adjuster polydrive bolt had sheared off also. For luck I was able to get the bolt out of the cam no problem but it ended up shearing the alignment pin off on the adjuster. Is the alignment pin available separate or am I going to have get a whole new adjuster? I haven't been able to find anything on it so I am assuming it is not but thought it was worth a shot. Thanks
