Car appreciation... the aesthetics, the engineering, etc

How come it's £180 BTW?

Even the multiple socket size sets I'm seeing are <£20, and the sensors seem to be £40-60.

I would say that with information available today there are lots of simple jobs you can easily diy on modern cars. Equally there are lots of simple jobs which are incredibly hard.

Eg

• VAG pollen and air filters (just unscrew a few screws and pop replacements in)
  
• Mini blocked washer jets (remove and rince tank out... after removing wheel and all arch covers without loosing or breaking anything)
  
  

Fyi it may be done up very tightly and you should double check whether you are meant to lube the threads or not.
