206 hdi 135.000 maintenance

Friends of the vehicle approached 135,000 kilometers, and I want to have a maintenance in general, there is no problem in the vehicle, just a noise like metal squeak on the right road from the front right, brake discs and pads have just changed, what are the things to do.
I am waiting for the advice of more experienced peugeo users. Would you also recommend a good master in vehicle izmit?

Change the filters, change the oil, make sure the trigerin has changed, so if you are not sure, change it definitely.

I will change the indispensable room such as oil, filter, the timing unchanged room will change, but apart from these, what are the parts that must be checked or need to be changed?

Have your linings checked except for this, but there is not much to do, if you want to be comfortable, you can have the injectors checked.

sometimes there is a sound like metal creaking on rough roads from the front right.
