What it means

P06E0 means the engine control unit, or a separate glow plug control module, has detected a voltage or current in the cylinder 11 glow plug control circuit that is lower than expected when it checked the circuit. This points to a short to ground, excessive current draw or a fault in the driver for that circuit. Cylinder 11 only exists on engines with at least eleven cylinders, and how the glow plugs are driven and numbered depends on the model and engine.

Symptoms

Engine management warning light on
Harder or longer starting in cold weather
Rough running or white smoke on a cold start
Slightly higher emissions or fuel use during warm-up
Glow plug warning light flashing or behaving abnormally on some models

Possible causes

Glow plug control wire for cylinder 11 chafed or shorted to groundlikely
Glow plug for cylinder 11 shorted internally or drawing too much currentlikely
Corroded, damp or damaged connector or terminal at the glow plug or control modulepossible
Glow plug control module or its output driver for cylinder 11 faultypossible
Blown fuse, faulty relay or poor power or earth supply to the glow plug systempossible
Fault inside the engine control unit, or a software issue where the manufacturer lists one for this enginerare

How to diagnose

Read all stored and pending codes and the freeze frame data, noting engine temperature and battery voltage when the fault set, and look for other glow plug codes.
Check the battery condition and charging voltage, as low supply voltage can upset glow plug circuit diagnostics.
Check the relevant fuses and relays for the glow plug system, following the wiring diagram for the specific engine.
Visually inspect the wiring, connector and terminal for cylinder 11 and the glow plug control module for chafing, heat damage, water ingress or corrosion.
Measure the resistance of the cylinder 11 glow plug and compare it with the other plugs and the manufacturer's specification.
Check the control wire for a short to ground with the connector unplugged at both ends, and check the module supply and earth.
Use a scan tool that supports the system to run the glow plug output test and watch the commanded and actual state for cylinder 11.
If the wiring and glow plug are good, check for a software update for the control unit or module, then consider the module itself.

How to fix

Repair or replace the damaged wiring or connector for the cylinder 11 glow plug circuit.
Replace the faulty glow plug, using the correct specification and tightening to the manufacturer's torque.
Clean or replace corroded terminals and secure the connectors, sealing out moisture.
Replace the blown fuse only after finding the cause of the overload, or replace the faulty relay.
Replace the glow plug control module or repair the engine control unit if testing shows the driver has failed.
Apply a manufacturer software update only if one is documented for this fault.

Can I keep driving?

Medium severity

The car can usually be driven short term, as a single glow plug circuit fault mainly affects cold starting. Get it checked soon, because a shorted circuit can overload the control module, and cold starts may get worse.
