I can see you're determined to have your car pass first time, but you are going to unnecessary lengths to do so. What I would recommend is to put the car through the NCT without doing anything. If you fail, correct the problems they tell you to. What you have listed below (1-5) goes without saying. 1. Do not change the oil if you don't need to. Make sure there is enough oil in the engine, that's all. Out with the dipstick and check the level. The water they are referring to is the water in the cooling system. Check your water expansion bottle to make sure there is enough water in the cooling sytem. Check your manual if you're not sure where it is. 2. The correct tyre pressure should be located in your manual or it can be found on the inside of your car's front right hand door. 3. Make sure they work, do each of the jets spray water? Are your wipers in good condition? Are they cleaning the water from the windscreen effectively? If so, you're good to go. Make sure you have enough water in your windscreen reservoir also. 4. Yes it is possible, 9/10 times it's the bulb, so if you've any bulbs not working, get to Halfords or Auto Care and replace them. You will fail if 1 bulb isn't working. They always check the bulbs. 5. 1.6mm of tread depth is the minimum tread depth for your tyres in Ireland. Make sure your wheel nuts are secure and that the wheels aren't damaged/buckled. Best of luck and as I said, don't let them waste any more of your time. Just put the car through and see what they say.
