2010 New Generation Saab 9-5 Service Vehicle Soon
Very fustrating as not very happy with SAAB. I had this problem before when the SVS "Service Vehicle Soon" warning comes up in the centre info display and the car goes in to limp mode. When you do a diagnostics it comes up with various fault codesP0396 and various other P03 codes. The codes will direct you towards a DPF sensor and cylinder pressure issues. What is causing the SVS light to come on and the vehicle to go in to limp mode is to do with the pressure sensors on the glow plugs and build up of soot on the sensors located at the bottom of the glow plugs.
Vauxhall issued a Technical Service Bulletin in 2010 relating to Engine A20DTx - Engines effected are A20DTH/A20DTJ. A20 DTH is the Saab 9-5 and Vauxhall Insignia 2.0CDTI. Glow plug with prssure sensors related failure codes and suggest the vehicle be recalled and a reflash be done with the latest software available as per CW40/211 on TISWeb. The new software will not activate the SVS light any longer in terms of malfunction from the glow plugs. Guess what Saab did not mention or offer a solution and Vauxhall will not do the software download required. Thus you have to replace all 4 glow plugs at a cost of £100 each total £400 every 2 years plus the labour associated to fit these glow plugs.
I have experienced this before and at a great cost to myself eventually (after being charged for and EGR Cooler, A DPF sensor and a regeneration of the DPF to no avail) tried to get a Saab dealer to do the upgrade but without an success. This particular dealer even invested in the latest software to read the codes on the NG Saab 9-5.Therefore had to replace the 4 glow plugs (part number 55590467) in April 2016. Three years later the same problem costing me now another £500. Certainly someone in Saab must know about this issue and can do someting about it in stead of us spending money for such a simple workaround.
If anyone associated or know of anyone that can have a word with Saab then maybe all the New Generation Saab 9-5 owners that remain loyal to the brand can get some help. I have seen various posts relating to this problem on the forums and can imagine that I am not the only one that has gone or will be going through this.
