Not sure if you've still got the car, it being 2 months later, but at 108K you should have a year or 2 left in it. However as you rightly say (and I'm at a similar place with mine) there is a point when spending more money on it has to stop. That said, being the sceptic I am, my first thought is ....is the garage you used reliable ?, or did they say just that there was a bigger problem because they were unable to solve a simpler one ?. My suggestion is twofold, 1, if I were in any way suspicious of the accuracy/integrity of the garage I used, I would have it checked again by another garage to confirm. And/or 2, depending on cost, try a different ABS Module/pump based on seeing on the eBay picture as to whether or not it looked identical. Point to note, In the past I've been very successful in buying parts for unusual car base on assessing the advertise picture(s), and only had a problem when the picture wasn't actually of the part being sold !!! Good luck.
