If you can afford buying a petrol car, do the swap now.

Your engine sounds like it has very limited life expectancy.

There is a series of checks you have to do but they will cost you money.

You need to check the injectors that they are not leaking.

You need to check the oil pick up that is clean.

You need to check whether your engine is one of those which needed rebuilt.

The turbo suffers from bad oil circulation. So if your injectors are leaking and the dealer spotted this problem, sooner or later, your engine and/or turbo will give way.

Any knocks from the engine are a big no, no matter whether it is a petrol or diesel. I would not drive this car with the engine doing that.

Just an fyi, it turned out camshaft on my car was warn out, metal particles in oil blocked oil strainer and caused damaged to turbo due to oil starvation. In case anyone experiences hesitation in their Mazda 2.2 diesel from 2012/2013 production years, inspection of camshafts might be necessary.

Look at life through the windscreen, not the rearview mirror.

You can reset your oil light after an oil change by using Forscan and a bit of wire to earth a special connection in the fuse box under the bonnet. Think I saw something on this forum somewhere. I have done it myself , but on a Gen 3 and it works. You can also connect up the wire , turn on the ignition engine off and press the accellerator 5 times in 5 seconds.
If you contact Mazda UK they will send you the info for your car as fuse boxes may vary.

Despite driving over 13k miles/year I  still require to change the oil every 6500 miles, just as they say in the handbook
about very low mileage driving.

Many thanks to Mareng73 for that comprehensive reply.
Problem/resolution  by you described exactly , I am sure.
The car was bought in 2018,  10k on clock , from Milcar Mazda , with a 12 month warranty and I wrote to the main Mazda Tech people ,explaining problem  after RED light came on after 6500 miles , mostly motorway driving.
They blamed my driving and changed oil/filter  under warranty.
Of course , it kept happening every 6500 miles thereafter , out of warranty.
 Crooks , by any other name.
We never had these problems with the Sulzer RD90's , a proper engine !

HI all

Re the DPF warning coming on after 11,200 miles. I understand the light is also used as a service indicator and has to be reset when the oil is changed otherwise the ICU thinks the oil hasn't been changed and tells you so. I had my 6TS serviced at a local independand garage and this happened 1100 miles after the service. The garage claimed they knew nothing about resetting the service indicator which isn't included in the open service software they have. It cost me another £200 for a second oil change and a reset at the main agents, whom I don't like due to their patronising attitude. It seems that only Mazda agents have access to this particular bit of kit. If true it sounds very like protectionism at our expense.

If you equip yourself with a wifi OBD reader and Forscan lite software, downloadab?e   at about £4  you can reset oil condition after changing it.
