Hello, is there anyone able to permanently eliminate the noise of the 1.6 TDI CR injectors?
I am attaching the file of a Golf 6 with pcr2.1
Thank you

Downgrade sw before diesel gate or your injectors are in bad condition

On 1.6 you have to remove a valve on injectors pipes which it gets blocked always and you have to re-adapt with VCDS min. Fuel quantity and its done!

No injector noise anymore.

As you can see on the image .. where the unburned fuel gets back from injectors on the end of the pipe.. there is a plastic valve.. you have to remove that valve and connect the pipe again but without the valve!

You can adapt injectors minimum fuel quantity with VCDS - > engine -> enter security code -> and you will find to adaption list.

Please dont forget to press thanks and rep!

No need any downgrade

Just find the proper valve .. remove it , connect pipe and do with vcds

The adaption time will take around 10 minutes and after that just drive a bit and u will no hear any noise anymore!

I have fixed too many like that.
