Vectra B
|
Subject: A number of complaints have been received concerning temperature gauges reading high ( in red zone ).
Vehicles: Vectra and Omega B with X20XEV engine.
Condition: There are a small number of engines manufactured with a defective temperature sensor supplied by Zertan in Spain. Defective sensors can be identified by the manufacturers logo and production date stamp between 98/12 and 99/07 which are stamped on the hexagonal flats of the unit as shown below.
Remedy: Please carry out a cross check with Tech 2 and verify the engine temperature by using the coolant temperature sensor for the Fuel Injection system. If the coolant sensor shows a different temperature reading than the temperature gauge, the temperature gauge sensor is defective.
Parts Information:
Description Part number Temperature Sensor 03 439 088
Sensors from supplier VDO are not affected. The warehouse stock has been cleared and all delivered parts are OK.
Important Information: At the moment we are only aware of problems reported on Vectra and Omega with X20XEV engines produced in Kaiserslautern ( X20XEV 14......). Astra G and Zafira are not affected by this concern. If any other engines are found to have the same concern, please feed back this information to us.
Please check your stock and ensue that Zertan sensors in the affected range are not used for remedial action.
