Recalls: Mercedes-Benz W639 Viano
- In August 2006, a recall was issued for Mercedes-Benz W639 Viano vehicles due to a possible software fault in the Supplemental Restraint System (SRS) control unit which could prevent the generation of a crash signal in the event of a rear-end collision (PRA 2006/8684).
- In March 2008, a recall was issued for Mercedes-Benz W639 Viano vehicles with the 3.7-litre V6 engine due to a potential fuel leak or hose detachment at the connection points between the fuel supply line from the tank and the engine (PRA 2008/9911).
- In January 2009, a recall was issued for Mercedes-Benz W639 Viano vehicles fitted with curtain airbags and manufactured between 24 June 2008 and 15 October 2008. In these vehicles, complete unfolding and inflation of certain curtain airbags could not be guaranteed – this would compromise the effectiveness of the airbags and place occupants at additional risk of injury (PRA 2009/10570).
- In August 2009, a recall was issued for W639 Viano models manufactured up to 15 April 2008. In these vehicles, the retaining mechanism for the underslung spare wheel could fail and allow the wheel to detach from the vehicle and pose a hazard to other road users (PRA 2009/10963).
- In February 2010, a recall was issued for Mercedes-Benz W639 Viano vehicles manufactured from October 2005 and December 2005 and from March 2006 to April 2006. In these vehicles, the adhesive between the left and right rear vent windows and their forward mounting hinges may be insufficient. As a result, the window pane could unexpectedly detach from its mounting point and pose a hazard to other road users (PRA 2010/11456).
- In October 2010, a recall was issued for W639 Viano vehicles because the air conditioning fan relay could fail in extreme weather conditions due to localised overheating; the chassis numbers for the affected vehicles were in the range of 378470 to 562988 (PRA 2010/12073).
- In November 2010, a recall was issued for W639 Viano vehicles with serial/chassis numbers in the range 177393 to 257781. In these vehicles, the adhesive between the left and right rear vent windows and their forward mounting hinges may have been insufficient, as per the February 2010 recall (PRA 2010/12120).
- In June 2011, a recall was issued for W639 Viano models fitted with the 2.1-litre turbo-diesel (OM646) engine and manufactured between June 2007 and October 2010. In these vehicles, the alternator wiring harness may have been incorrectly routed and could contact other components – at worst, this could result in a short circuit (PRA 2011/12660).
- In February 2012, a recall was issued for Viano models fitted with the 3.0-litre turbo-diesel (OM642) V6 engine and manufactured from August 2010 to May 2011. In these vehicles, the fuel filter could leak and the fuel could a fire or skid hazard (PRA 2012/13036).
- In March 2012, a recall was issued for W639 Viano models produced between 1 February 2011 and 31 July 2011. In these vehicles, the ‘A’ pillar trims may dislodge from their mountings if the window airbags were deployed during an accident, potentially striking the occupants (PRA 2012/13070).

OM651 timing chain and tensioner wear
