My 2015 Octavia 1.6, 154k on the clock drops power dramatically when it’s ready to regenerate, no warning lights appear, it’s just like if it was in limp mode but after a couple of miles it’s fine again .

On my 2016 50k 1.6TDi the fuel consumption drops a bit, but I don’t notice a loss of power during regeneration . Does your DPF need a clean out?

Forgot to say I’ve had DPF cleaned out improvement

How often is the regen process taking place. Once a tank is about normal. If you are in a town, try taking the car out onto main fast roads and giving the car an Italian tune-up (fast, hi revs, high speed driving). Failing that I've discovered that putting in a cetan improver into the diesel can massively improve performance and and keep your EGR valve and DPF in tip top performance.

I find running on Shell V Power diesel helps keep the engine running better. It does cost more but I find I get better mpgs aswell. Plus it has additives and cleaners to clean the fuel line and injectors so win win for me.

The Regen is quite regular as I am aTaxi driver and cover 100 miles per day approximately, I have never put any additives in my fuel but I use Shell V Power all the time.

Always use Shell V Power nothing else I bought the car with10k on the clock and I have never used any other fuel, 99.9% of the time the car runs as sweet asa nut, I have only had to replace the Alternator in the 4 years I have owned the car,

I think an Italian tune-up would help. Doing lots of stop/start work will cause issues.
