Last day the EML came on and when I scanned using an obd2 reader, the error was P0673. The car was also complaining about low battery (it is about 6 years old) for few months. So I got a new battery and took to the local garage. They said there is a chance one of the glow plug will have a pressure sensor and if so it will be more expensive to replace. I asked to replace the pressure sensor one only if it is causing the issue otherwise replace the normal ones anyway,
After working on the car (replaced battery, and there was another error P2102 when they scanned), the garage said there were no glow plugs with pressure sensor and glow plug cylinder 3 was malfunctioning. They renewed glow plugs in cylinder 1,3 and 4. They couldn't take out the Cylinder 2 glow plug as it went tight when trying to undo it and they fitted it back. The car is an Octavia III 2.0 TDI 110 kw. I saw this post where glow plug with pressure sensor is discussed.
Does anyone know if this model would not have the glow plug with no pressure sensor? Any help will be much appreciated.
Thanks.
