BMW Australia is recalling more than 2900 vehicles across eight of its model ranges due to an issue related to three of its turbocharged six-cylinder petrol engines.
The fault stems from a lose connection on the housing of the Valvetronic variable valve timing unit on turbocharged 2.5- and 3.0-litre N51, N52 and N55 engines. It affects 2930 vehicles built between October 1, 2009 and April 30, 2012.
According to the official recall notice on the Australian Competition and Consumer Commission’s (ACCC) product safety recalls website, the issue potentially impacts on eight BMW models including the (E70) X5, (F25) X3, (E87) 1 Series, (E90) 3 Series sedan, (F10) 5 Series sedan, (F07) 5 Series GT, (E63) 6 Series Coupe and (F01) 7 Series.
The notice states the loose connection may cause the valve timing system to not adjust quickly enough to any drop in oil pressure, causing the vehicle to go into ‘limp’ mode and illuminate the engine warning light. The fault could possibly result in an internal oil leak.
“If the vehicle is being driven and slows down or stops unexpectedly this poses an accident hazard to the driver and other road users,” the notice says.
BMW Australia corporate communications general manager Lenore Fletcher told CarAdvice that not all vehicles fitted with the engines are affected and that a very small number of vehicles have presented with the issue.
“It is dependent on vehicle identification number (VIN) and includes varied production dates for each model,” Fletcher said.
Fletcher said it will take four hours to rectify the engine fault, with no accidents or injuries related to the recall reported.
In October last year BMW Australia recalled 2893 vehicles across six model lines due to a vacuum pump fault that risked diminishing vehicles’ braking performance and in March 2012, approximately 10,000 BMW 5 and 6 Series vehicles were recalled to address a potential defect with the cars’ battery cable covers.
