What does this fault code mean?

The control module has detected a signal that is too low in the circuit to the glow plug for cylinder 4. The glow plug heats the combustion chamber at start, and when its control does not work a cold engine becomes harder to start. The code is general and does not say what type of fault it is.

Possible causes

Contact resistance or oxidation in the connectors
Signal wire short-circuited to ground
Defective glow plug control unit

What you can do

1Read and note the fault code, clear it and start the engine when cold to see whether the fault returns
2Check that the fuses for the glow system are intact in the owner's manual
3Look at the connector on glow plug 4 and the wiring for loose contacts, oxidation and chafed spots
4Use a multimeter to check that the wire to glow plug 4 has no contact with ground (the body), with the connectors disconnected
5If you have a diagnostic tool, you can activate glowing and see whether cylinder 4 is included
6If the fault remains after these checks, have a workshop check the glow plug control unit

Symptoms you may notice3

Engine hard to start and cranks slowly
Problem noticed at cold start
The problem may also appear after use, and it is hard to say when it occurs

What the fault can affect1

Glowing is switched off for the damaged glow plug
