The BMW 118D E87 N47 is a diesel-powered vehicle.

Hello, I am interested in remapping my 118d. I have learnt that it has the potential to reach about 190 horsepower. I purchased the car a few weeks ago for the price of £xxxx. It had just 21,000 miles on it and came with a complete service history.

I'm enquiring about the need of having the chain replaced before the map, or whether it would be OK to wait a few months, since the vehicle is in pristine condition.

The chain seems to be in good condition.
However, while operating at that level of power, be attentive to any auditory disturbances and promptly make adjustments upon detecting any.
Uncertain about whether you will achieve the suggested miles, although it is difficult to predict.

Frankly, I am considering resolving the issue with the chain to avoid any concerns or difficulties.

The choice to do chain maintenance on a low mileage vehicle like that would depend on many factors.

Has the automobile undergone maintenance in accordance with BMW specifications or has it had additional oil changes?

What is the age of the car? If it is an early N47 model, it is more susceptible to experiencing failures.

I am uncertain about the frequency of upkeep, but I believe the automobile has had regular servicing and it is registered as a 2009 model.
