if you have an ignition amp stick with the factory airbox and put a green cotton / K&N in it rather than a cold feed pipe

you need to clear the codes off and see what comes back. They might be years old

Also if the ignition amp is faulty it won't throw up a code

Not yet, sort the other codes first

camshaft position sensor looks easy enough, it's just on the drivers side front of the head

Coolant fault

 16500/P0116/000278 - Engine Coolant Temp. Sensor (G62): Implausible Signal
Possible Symptoms

    Starting the engine when engine is warmish or warm, idle rpm immediately is 1200 - 3000 rpm.
        Diesel: an indication is extreme long time burning time of the glow indication light.
    With all engine temperatures seldom idle rpm will vary between 900 - 1000 rpm.
    With engine warm (90 °C) the engine temperature suddenly drops (70 °C) and slowly comes back to 90 °C.

Possible Causes

    Wiring and/or connections faulty
    Engine Coolant Sensor (G62) faulty

Possible Solutions

    Check wiring and connections
    Replace Engine Coolant Sensor (G62)

Special Notes

In MY 1995-2002 (?) in Europe at VW-cars the G2/G62 had the bad reputation of breaking down often. The default G2/G62 is black and all replacements are green.
Check if the correct Coolant Fan Control Module/Relay is installed (check part number using parts catalogue)!

Speed sensor is easy enough to change too
