BMW N63 V8 Timing Chain Inspection and Replacement, TSB 111614, CCP
As noted in the prior posts related to the N63 engine CCP (Customer Care Package), which covers a few issues related to BMW models using the N63 twin-turbo V8 engine, timing chain stretch is a common problem. BMW has now issues a separate Service Bulletin (TSB 111614) that specifically addresses the timing chains on all models with the N63 engine.
There is still one caviat to this whole thing ….. the procedures are only covered at no cost if the vehicle is still under some type of warranty (original vehicle warranty, extended warranty or pre-owned warranty). Unless a dealer opts for a “good-will” repair (dealer covers some or all of the cost), the repairs are charged to the vehicle owner. The saving factor here may be that the N63 CCP covers vehicles that are out of warranty as well and the CCP does address the timing chains. Confusing? Sure.

The sweeping program also extended to vehicles that had gone out of warranty, without concern for mileage on the vehicle. As of February 2015, both the US and Canada are implementing this campaign.
Additionally, the service interval would be shortened to nearly half, with a 12 month/10,000 mile (16,000 km) check-up instead of the long-life treatment the BMW had been maintaining up to that point, requiring a check every 2 years and 15,000 miles (25,000 km).
in June 2013, dealerships had received a service bulletin regards to the N63 powerplant, which amended the oil capacity requirements of the engine, adding a full (1) US quart to the capacity of the motor, citing “increased oil consumption” in the twin turbo V8.

- F01 and F02 (7 Series Sedan)– produced from 3/2009 to 6/2012
- F04 (Active Hybrid 7)– produced from 4/2010 to 6/2012

The dealership bulletin was accompanied by region sales rep meetings with branch/service managers, informing them of the forthcoming campaign, and issuing instructions to contact all owners serviced at their branches operating the N63 engine. The accompanying marketing campaign, which would be a major focus for 2015 of BMW world-wide, was intended to dampen the effect of such a wide spread recall on BMW’s waning brand loyalty and customer service issues, the tactics of which could be seen in the extended efforts surrounding the recall.
BMW dealerships were instructed to offer extra incentives for owners affected by this campaign, offering trade-in cash bonuses for their N63 equipped vehicles with the purchase of a new BMW (details in a separate sales bulletin – “N63 Customer Loyalty Offer”). Sales teams were also provided with discretionary authorization to provide customers with a gift of $50 value, including anything from a gas card, gift bag containing BMW Lifestyle products, or vehicle detailing.
