Heck, Neil  you got three good years out of the thing....and the next one
cost you thirty bucks, you said?  I paid $35 for a spare that I have....
   I guess $12/yr for ECUs, that could be affordable.....

  I am joking here in a way that points out how cheap parts are for the
Jetta/Fox/Rabbit motors...and I am joking about spending hours and hours
figuring out why your $30 ecu failed after only three years (of you using
it)....
   I know, a learning process and kinda like doing the cross word puzzle if
they still publish those......

  I recall them wanting $2800 for a used rebuilt ECU for my Porsche 928...
