Hi - 2010 Saab 9-5 2.0 TID4 2.0 Diesel. Has anyone had a fix from their repairer for the following ongoing problem. The vehicle is fitted with glow plugs that has got sensors in them. If the sensors get clogged up with carbon build up it will send a message to the engine ECU and a "Service Vehicle Soon" warning will come up in the centre display. The vehicle will then go in to limp mode. Vauxhall issued a download and fix on all Vauxhall Insignia 2.0 CDTI models with the same problem. Saab did not do this and Vauxhall Dealers can and will not do the fix. Therefore you have to replace all 4 glow plugs at a cost of £450.
Can anyone suggest a long term fix without replacing the glow plugs please?
