This bulletin applies to 2013 BMW 528i xDrive vehicles with the N55 engine and manual transmission and Continental high-pressure pump. The engine may not start on the first attempt when cold.
The different N55 variants can be determined by reading the vehicle’s plant integration level. N55 with MEVD172 (Continental HDP) are older than F010-12-03-500. The engine turns over but does not start on the first attempt. It will normally start on the second or third attempt. This occurs sporadically, usually at low ambient temperature and when the engine is cold.
The cause is unfavorable DME software in conjunction with a partially charged battery. Program the vehicle using the latest version of ISTA/P 2.50.2 to the target integration level. The target is F010-13-07-503 and higher.
