Dear readers,

I just replaced the timing belt on my Golf IV SDI, engine code -AGP-. Now, I want to use the VAG COM tool to check the fuel injection timing.
'Where can I find the diagram showing the start of fuel injection (as a function of fuel temperature and other factors)? In the past, this was often done using a micrometer. Unfortunately, I'm not quite familiar with VAG-COM yet, and most importantly, I'm missing the diagram.'

Are there any SDI owners who have the wiring diagram for the Golf IV? Unfortunately, the Polo has a different diagram.

Thank you very much.

Hello, it's been a while, but here's the information:
Up to production date 04/99: Field 2: 55 (Injection start); Field 9: 90 (Fuel temperature).
Field 2: 51 (Bb) ; Field 9: 110 (Kt)
You can create a diagram from the data.
From production date 05/99: Field 2, range 25-78 (ideal 55); Field 2: 90 and above.
