"Glühstift Zusatzheizung" nachrüsten ? | Posts 16+

I took that picture with my brother's digital camera. I even still have the original image, but you can't make out the number much better in it either.

Likely number.

Block 1: 8A0 or 6A0.
Block 2: 810 or 818.
Block 3: 487 or 497.

@ Kusi
Disconnect the glow plug connectors and take a piece of 1.5mm² wire. First, connect one end to the glow plug connector (due to the risk of short circuit), then take the other end and touch it to the positive terminal of the battery.
If the glow plug is intact, you will soon hear the water in the flange start to boil. Repeat this process with the other two glow plugs.

Best regards, Andy.

@ Andy

Thank you for the advice. I'll definitely try it out sometime soon.

Kusi.
