Owners of Mercedes classic cars (W126, C126 and R 107) are aware of the problem. The two-pole idle regulator is hard to find and then not exactly at a bargain price of 500 to 800 Euros.
It is also difficult to find it in a scrap yard, because the years of manufacture 1985 to 1991 are rarely found in scrap yards. Autosensorberlin has therefore added two more idle speed controllers for Mercedes-Benz vehicles to its range and offers them in proven LÖWE quality.
The idle air control valve (IACV) with part number 5351625 fits the models W126, C126 and R107, and replaces the reference number 408-202-010-001, 408-202-010-002Z, 0001411625 and 1411625.
It can be ordered here.
Also new in the range is the idle speed regulator for the 500 SE (W126 and C126). It replaces the Mercedes number 0001411425, or the VDO numbers 408-202-004-003Z and 408-202-004-002.
Please first match the numbers on the originally installed old idle control valve with our reference numbers. If everything fits, you can order here:
