So I got
my car back today with two new turbos. Ran it through its paces and no problems so far. No more engine ticking. Hopefully all is back to normal.
As you can see, it looks like BMW is routinely looking for aftermarket parts to deny coverage. Luckily my car is clean because realoem lists the chargers alone at $1900 a pop.
Below is the writeup, typos and all. Any BMW people want to take a look at the codes, SIB, or case number to see if there is any more info to give us?
RAN SHORT TEST. RETRIEVED FAULT CODE 20FF STORED UNDER DME 5 TIMES. NOT PRESENT. FOUND SIB 12 28 07. CHECKED NO AIR LEAK OR RESTRICTIONS. NO AFTER MARKET MODULES INSTALLED. DID THE MEASSURED ACCORDING TO THE SIB. ALL THE MEASUREMENT NORMAL. BUT FOUND THE BOTH TURBOS ROD NOT MOVING WHEN APPLY VACUUM TO THEM. SENT TC CASE TO REQUEST REPLACEMENT. CASE NUMBER 30634913 APPROVED TO REPLACE BOTH TURBOS. REPLACED THE BOTH TURBOS. CLEARED FC.
