I just realized you're in the Netherlands. Toyota only seems to be taking their time taking care of the US customers.
Is the coolant pump part of the recall? I had my steering shaft replaced 3 months ago and just submitted my receipt to Toyota for reimbursement when I got the letter. However I saw nothing about a coolant pump.
You do not give any indication where you are from but you can check on the Toyota web site or wait for a letter from them about the inverter coolant pump.
