Fuel Injector Calibration: How-To Guide

Translated on 16-09-2026, 9:07.

Hello everyone, I'm new to this forum and still getting familiar with it. I also have a question for you.
I own a 2012 Caddy with the 1.6 CR diesel engine, identification number CAYP. The problem was that one of the fuel injectors was defective (the old one was 03L130277B, and the new one is 03L130277S). Do I need to program the new injector, or will the engine management system automatically adjust the learning values for the new injector?
I hope you can give me some advice.

Thank you in advance.

Yes, you need to calibrate/adjust the injector.

Can someone explain to me how to do this using VCDS? That would be great, thanks.

If you have VCDS, use the same email address for the forum as you do for the shop, and try logging out and logging back in – there might be more information available then.

I've been searching for hours and haven't found anything. Could someone please help me?
I'm still not quite getting the hang of all the forum's functions, but I'm trying my best

Hi Tobä!

Were you able to understand everything that the weasel wrote above?

But I'd be happy to explain it to you in more detail.
Without a valid VCDS license, there is no support available here - END

Playing dumb doesn't make it any better...

Best regards from Munich!

Hello everyone!

@Tobä, I have to apologize to you upfront...

I didn't know that Gerrit had lent you his VCDS and I suspected that you were using one of the -unfortunately- many pirated copies.

Take a look here to see if this helps you or your team.

Thank you all for your efforts. I understand that you're being cautious, and I'm not upset about it in any way. That's why Gerrit got involved to get more information. But everything is fine, I managed to fix it, and it turned out to be easier than I thought.

Thank you again, everyone.

Best regards, Tobe
