DETAIL
Please remove issue 1 6O/05/95/US and replace with issue 2. The SRO for re-calibration had previously been omitted.
It is possible for early front height sensors on the Range Rover 4.0 SE's to experience water ingress problems. This condition can result in the following
fault codes being set:
1.
Front height sensor out of range (left or right)
2.
Front corner valve stuck closed (left or right)
The condition may also cause repeated levelling changes to maintain a given ride state without flagging a fault code.
A revised height sensor was introduced at VIN 306631. This sensor is easily identified by having a "glossy" wire lead (old condition sensors have a matt
finish). Also on the rear of each sensor there is a unique date code. The production change was made at date code 34994, (the sensor being manufactured
during the 349 day of 1994). Any sensors with a code after this will be to the revised design level.
ACTION REQUIRED
Upon customer complaint of an EAS fault that shows front height sensor out of range or front corner valve stuck closed, follow the procedure below.
