Potential complaints:
■ Limp home mode
■ Regulating throttle does not work
■ P0638 “Throttle valve control – circuit broken”
On the vehicles listed above, water or moisture may infiltrate through the coupling of the connecting cable. This moisture may cause severe
damage in the interior of the regulating throttle, leading to eventual failure.
To avoid this you should check whether there are visible traces of corrosion or moisture on the built-in plug of the regulating throttle or on the cable coupling. If this is the case, then replace the regulating throttle and cable.
Replacement throttle
From the start of series production, a regulating throttle with the reference number 7523D has been installed in the vehicles mentioned. During series production (from 2009), this regulating throttle was replaced by a PIERBURG regulating throttle.
The regulating throttle 7523D installed until 2009 can be replaced by the PIERBURG regulating throttle 7.01754.10.0 using the adapter cable 4.07360.49.0. This adapter cable is sealed to protect against moisture.
