Car troubles again

For a couple of months, I’d been getting the “engine problem” light and each time it went to the garage, the onboard computer reckoned there was a different fault. The vacuum pump, glow plugs, mass air-flow sensor and oil level all caused it at one point or another.
Not content with this, my car has now got a slow puncture on the back tyre and the locking wheel nut key snapped when the garage was getting it off! Gonna cost me yet more money to get it sorted tomorrow 🙁
