Firstly i replaced my engine coolant sensor a few weeks back. Flashed up code 21 on CEL light.
After replacing this its flashed up again!!! Why???
Secondly, after cold start up i can hear ticking coming from the left side of the engine. It aint the solenoid ticking. Could it be injectors?
Its starting to do my head in now as iv had no luck with this car whatsoever.
Any help would be great
