Over the weekend I'm planning on replacing a few parts on my Golf 1.4 'L'.
I changed the oil pump and one of the pressure sensors around 2-3weeks ago and although my oil light does come on its not as much as before (virtually all the time) now it only comes on under around 1,500-2,000rpm so I'm guessing its the 'other' pressure sensor that I need to change as I only changed the one.

Here is a picture of my engine with the sensor highlighted in red. Does anyone know where any other oil pressure sensors are on my car?
And which one I need to buy, here is a list from GSF Car Parts.
Secondly, I changed my headlights to Mk4 style lights a while back and have noticed people flashing me. I've worked it out that one of my bulbs is flashing! When I stood in front of the car the other day I noticed it flickering, is this a sign of a dead bulb?
Do you know where I could pick one of these up? What bulb is this? Front Fog? :/ I dunno
Is this the bulb?

Any help is greatly appreciated. This forum has helped me so much since I've owned my Golf!
