Tested and overhauled Bosch warm-up regulators for the K-Jetronic (part numbers 0 438 140 …) – for classic Mercedes-Benz like the W107/R107, W116, W123, W126 as well as other vehicles with Bosch K-Jetronic. Every regulator is tested before shipping.

Your own warm-up regulator is faulty? We overhaul your regulator for a fixed price of 400 € incl. return shipping – so the genuine part with the matching part number stays in your car. Faulty warm-up regulators we buy for 50 € each.
