My 2002 Jetta TDI 1.9L has been throwing the glow plug dash light warning since I've been driving it (January 2019). The glow plug harness is pretty ratty, the rubber insulation is cracked and breaking apart. I'm assuming that is what's throwing the code/illuminating the dash light. Just wondering if any of you have an opinion on what harness I should get to replace my existing one.
Is there a way to test glow plugs to check if they need to be replaced as well?
What are the symptoms of faulty glow plugs/glow plug harness?
I live in South Carolina, so cold isn't really an issue until late winter. But even then it's well above zero (Fahrenheit) and I haven't had any trouble starting the car despite the glow plug warning. TIA.
