BMW has halted deliveries of the new M5 and M6 and is calling current owners to have their car flat-bedded to dealers due to an issue with the S63TÜ V8 engine. The issue lies in the oil pump which could fail and result in a sudden loss of oil pressure ultimately severely damaging the engine.
This impacts specific 2013 models, and if you recall Europe has had this engine for a year with no such issues which leads us to believe that this is a supplier not meeting their obligation to build parts to spec rather than a BMW M design flaw. You can read the full internal bulletin sent to dealers after the break.
A Delivery Stop has been issued by BMW AG to correct a potential problem with the engine oil pump on certain S63TU-equipped vehicles. Affected vehicles are the 2013 Model Year M5, M6 Coupe, and M6 Convertible. Vehicles equipped with an affected pump could experience a sudden loss of oil pressure which will result in severe engine damage. BMW Customer Relations is contacting customers that have already taken delivery and recommending customers not drive the vehicle. A Q&A will be provided to all BMW dealers in the form of an additional DCS message later today. This Q&A will provide you with the necessary information to answer your customers’ concerns. Vehicles included in the accompanying VIN list must not be delivered until the repairs are completed. Do not order any parts at this time. Sincerely, Technical Service
