What the Glow Plug Light (Diesel) Means on a Chery Omoda 5

Frequently Asked Questions
Why is the Glow Plug Light (Diesel) on in my Chery Omoda 5?
On a Chery Omoda 5, the Glow Plug Light (Diesel) comes on because a monitored value crossed a threshold the car considers abnormal.

Short answer: sometimes, but not indefinitely. Given this indicator's low priority, respect the warning colour and the car's behaviour. When in doubt with your Chery Omoda 5, the safe choice is to stop and have it checked rather than risk further damage.

Some fixes are almost free — tightening a cap or a connector — while others involve a sensor or component and its labour.

Will the Glow Plug Light (Diesel) reset itself on a Chery Omoda 5?
