Hi

Any codes stored?

Use a cheap OBD2 reader to get the C3 error codes.

Hello simuzer, you may have a faulty engine temperature sensor. So the ECU doesn't know when the engine is hot and alters the ignition and fuel incorrectly.

Your engine (TU3) probably has 2 engine temperature sensors fitted. One for the dashboard and one for the engine ECU.
The engine ECU one can be faulty and it is located on the coolant outlet housing at the gearbox end of the engine.
