KE Jetronic Troubleshooting

For most pre-1991 manufactured W124s, the fuel injection system on these engines are mostly using Bosch KE-Jetronic.

Though mostly mechanical in nature and lacking the feedback O2 sensor to correct the air/fuel mixture, it was considered sufficient in providing the control of the injection of fuel back in the days when fuel was still relatively cheap.

After 20 odd years, the KE Jetronic still delivers the fuel but probably not as efficient as there are several components in the KE Jetronic Fuel Delivery system that might have been overlooked by owners.

Key Components of the KE Jetronic(CIS-E) System

Rough starts, difficulty in starting, rough hot/cold idling, heavy petrol smell are all symptoms that the KE system needs to be looked at.

Clearing Choked Scuttle Drain on the W124

The W124 is a magnet for dead flora.

On dry seasons, one may not mind much about the leaves accumulating along the scuttle drainage paths.

However, once it rains, the scuttle drains might get choked and the dead leaves start to become compost and chokes up the drain.

As we live in the tropics and park under trees for shade whenever the ride is taken outdoors, there is an issue with dead leaves and branches choking this scuttle plenum drainage path.

Scuttle Drain Location

The drainage path for water coming down from the windscreen goes narrower as it guides the water down to the floor via a small piping.
