Hello,

I read on the net that you can have the injectors cleaned.

There are good home remedies to cleanse that.
Would like to expand and 'insert' it.

Unfortunately, since I wasn't careful in chemistry, I don't know
what means I can use to remove the carbon.
Oxalic acid?

Fingernail, emery cloth and knife.

This may be a horror for many here, but it is normal for us and it works without any problems.
It is only important that when cleaning the tip, the dirt is not smeared into the spray holes, so always clean at the appropriate angle of the blade towards the tip. After scraping the shaft, you can polish it a little with emery cloth, but also watch out for the tip (spray holes).

If you have doubts about your work, you can still pull the trigger from the injectors. A nozzle tester is sufficient, and in the best case scenario, a function generator with a power output stage (which you can also build yourself) is available.

Hello,

Fingernail, emery cloth and knife.


Then the injector is pretty safe in the bucket.
I suppose it's about the engine of the 320d.

Without a subsequent injector test, IMHo can save yourself the work.
Attempts to clean coked TDI injection nozzles both with ultrasound (110W with cleaning solution) and with mechanical cleaning were unsuccessful.
Either the dirt didn't come off, or the nozzle was in the bucket afterwards.

Regards, Rainer
