Temporary idle speed increase


Safety-related campaign 10294

Cars in stock must be remedied before delivery. A personal communication must be sent to the owners of cars already delivered requesting them to get in touch with the nearest Saab garage as soon as possible to have the fault rectified.

Cars concerned

Saab 900 2.3i M95 with manual gearbox or automatic transmission (in Sweden this MI only concerns cars with automatic transmission) equipped with A/C or ACC and having the following chassis numbers: S2000001-S2020094, inclusive, and S7010001-S7016141, inclusive.

Background

Idling speed on some cars increases drastically a couple of seconds after starting. This increase in idling speed may continue for up to about 30 seconds. It persists even if gear position R or D is selected on cars with automatic transmission. In these cases idling speed drops from about 3000 rpm to about 1500 rpm. Extra heavy pressure on the brake pedal is then needed to prevent the car from moving off.

The engine management system's control module must therefore be changed.

Materials

46 11 109 control module.

Procedure

Check box A1 on the modification identity plate. If it is not marked, change the control module. See Service Manual 2:7 "Engine management system MOTRONIC 2.10.2" .

Replaced control modules shall be sent without delay via the importer to the Arnö warehouse, see separate information.

Marking the modification identity plate

When the car has been rectified the modification identity plate should be marked with a "7" or an "8" in box A1.
