AFN Engine Glow Plug Fuse: What Size?

Translated on 30-09-2026, 21:43.

hello,

Are there more than one fuse for the glow plug system in the AFN engine Golf 3? If so, where might they be located? I found an 80A fuse in the fuse box, on the top right, connected to a relay. Is it related to the glow plug system?

Best regards,

The search would have helped you too.

The glow plug fuse often causes problems, and it is also well hidden in some vehicles: for example, in the 1997 Golf 3, it is located as an oversized flat fuse, poorly accessible on the top of the central electrical unit, while the owner's manual refers to the inner fender of the engine compartment.
In vehicles with a fuse box located on the battery, the glow plug fuse is usually located there.

I also found that, but I just wanted to know if there were more than one.

Hello,
If all the glow plugs receive their 12 volts, then no more fuses will blow.
Otherwise, the wiring in this area is so well-organized that...

What is the purpose of connecting multiple fuses in series?
