How it works

  1. Book the repair here – you'll receive the return address with your order confirmation by e-mail.

  3. We fully overhaul your regulator and get in touch if we have questions.

Why repair instead of replace?

Bosch no longer supplies new warm-up regulators. With the repair, your genuine part with the part number matching your vehicle is retained – important for the originality and value retention of your classic car. The refurbished surface also makes the regulator a showpiece again in the engine bay.

Prefer to swap it out right away instead of waiting?

We also have refurbished warm-up regulators ready in stock – with a 5-year warranty: View all warm-up regulators.
