A well-known issue with FSE units from the GR family is scoring in the fifth cylinder. There are two different theories: either a local overheating caused by a design defect or the infiltration of abrasives directly into the combustion chambers through a gap in the air filter. Defective valve springs. Engines produced from 2005 to 2008 were subject to a recall campaign for the replacement of defective valve springs, which could simply rupture due to impurities in the metal. Rattling of camshaft adjusters. A common problem with GR series engines is rattling of the camshaft adjusters upon startup. Sometimes it can be resolved by replacing the sprockets, but usually new couplings need to be purchased. Other problems. Weak points of the engine include short-lived AFS mixture composition sensors, lambda sensors, ignition coils, and the fuel pump. Also, there are often issues with fluctuating RPMs due to carbon deposits on the valves. In the engines of the early years, corrosion of fuel lines and leaks at the cylinder head gasket joints were occasionally encountered.
