TDI CAYD Engine: 1.6L, 75kW Performance

Hello everyone,

I have a Caddy with a 1.6-liter CR TDI engine. It has 420,900 kilometers on it.

Today, out of pure curiosity, I checked the calibration values of the injectors, and I noticed that according to VCDS, they are 7 digits long, but the injectors themselves only have 6 digits. According to VCDS, a zero is stored at the end. Is this correct, or should the zero be at the beginning?

According to vcds, the following value is stored for the injector (photo attached):
909DFG0



The injectors were replaced at 380,000 km.

Attached is a photo of an injector.

The engine runs relatively well, but it's a bit noisy.

best regards
axp

Hello,

"That's a good question, but if the engine is running well and there are no noticeable issues, I would advise against messing with the injector coding."
If I were to add a zero, I would place it at the beginning of the coding sequence, but I do so with no guarantee, as all my engines are 2.0 TDIs, and I have limited experience with the 1.6 TDI injection systems.

Best regards, Rainer.

Yeah it's a 6 digit code, I'm well aware of the additional 0 needed, but I tried all this already and when I attempt a coding it states a security access is required. Then I try whatever security access codes I have got but none work. (FYI I was a VAG dealer tech for 13 years, how simple things have changed!! Lol) Dana, I actually have a map stored for this, which I will post when I get near my laptop. But I'm not sure if it's going to be of any use. (Well, I hope I have one, as I've never used these before)

Okay, that works. Thanks again for the information.
