Engine Coolant Level Warning Lamp Illuminated – Volkswagen Golf
We are having trouble finding the cause of an engine coolant leak on a 2013 Volkswagen Golf 1.2 TSI. A coolant pressure check with the engine cold did not provide much help. After a road test when the engine was up to normal operating temperature, there were signs of a coolant leak near the airfilter housing, but we still cannot find the source of the leak. Can you help?
Yes, we have come across this fault before and it affects Polo, Golf and Jetta models with CJZA/CJZB/CJZC/CJZD engine codes. The engine coolant leak is due to a coolant pipe chafed through on the air filter housing. Fit a modified engine coolant pipe, complete with protective sleeve. The protective sleeve will prevent recurrence of the fault. Finally, ensure that the engine coolant level and anti-freeze content are correct.
