Is your warm-up regulator still OK? We measure it on our test station – control pressure cold, warm and with vacuum, tightness of the diaphragms and the heating element – and compare everything with the Bosch specifications for your regulator number.

How it works

  1. Book the test here – the shipping instructions arrive immediately by e-mail with your order confirmation.
  2. Remove the warm-up regulator, drain the fuel, plug the connections and send it well packed to KFZ Teile Thot, Widdersdorf 36, 84079 Bruckberg – with a note (name, phone, order number).
  3. We measure your regulator. Nothing is taken apart or adjusted in the process.
  4. You receive the result with the measured values. If the regulator is OK or you do not want to have it overhauled, it goes back at our expense. If it is to be overhauled, it stays right here – and the 49,99 € is credited.
