Where are the 307 1.6 hdi engine number friends

hello friends, I took the car to the inspection today, because the license is deformed in the inspection, the engine number should be read, but the engine number should not be found, you will go to some kind of authorized service. even the service wants 350 lira money Does this have a chance to be seen comfortably?

Then it makes more sense to renew the license. Page was 88 TL

First of all, welcome to us. As our suitor friend says, it is more logical to renew the license leaf.

The problem has been solved guys, I took the risk and got the catalytic converter casing on this day.
But this time, we had to disassemble the turbo hoses while inserting this casing, and when I gathered again, I felt a slight decrease in performance in the vehicle.

Get well soon. Exactly my teacher may not be seated properly or check the gaskets again. Is there any leakage?
