C0293 Volkswagen Crossgolf code definition:
C0293 is a kind of OBD-II Diagnostic C-Chassis Diagnostic Trouble Code for Volkswagen Crossgolf.
C0293 Volkswagen Crossgolf is defined as Cylinder 3 Injector Circuit Malfunction. This code means the PCM (powertrain control module, also known as ECM or engine control) has detected a problem in the injector or its wiring, or in injector circuit for cylinder 3. Other symptoms that may indicate this problem are when the Check Engine Light illuminates and when there is a visible lack of engine power.
Symptoms
Symptoms of a C0293 Volkswagen Crossgolf diagnostic trouble code may include:
- Faulty or damaged wiring
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Poor fuel economy
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.
|
Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code
- Rusty exhaust systems, cracked exhaust manifolds or damaged or missing gaskets or donuts will cause air leaks.
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Crankshaft Position Sensor Circuit Performance Problem
- TP Sensor Learn Not Complete Problem
- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- Kick-Down Switch Failed Short Problem
Repair Processes :
Pack the connector cavity with dielectric silicone compound (same stuff they use for light bulb sockets and spark plug wires) and reassemble.
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
