I changed the oil the other week on my 300tdi auto R reg. Once done the oil light flickered once the oil was warm/hot at tick over.

After searching these forums I changed the sensor and the light hasn't flickered since.

Should I be worried ? why did this happen after the oil change ??

Have you put back a different grade of oil, had previous owner put thick oil in due to problems.
Or did switch go faulty at same time as oil change coincidences do happen

It's usually a symptom of a sticky oil pressure relief valve, but if you changed the sensor and it's OK I shouldn't worry. If in doubt, I'd change the valve, which is usually a simple job (I haven't done one on that engine). Symptoms are high pressure at revs and low pressure at idle.
