Engine Cuts Off On Galaxy 1.9td1 130bhp 04

[z ali]

hi,i'm having problem with my 1.9tdi 04 galaxy and looking for some advice pls. first time it starts up fine i can drive as long as i want,then second time if it starts straight away then its ok but if it takes long to start which it does, then it will cut off straight away or it will run anything between 200yrds and a few miles,then cut off again. diagnostic shows d40 fault. can it be cam sensor? any advice pls.

Hi and welcome to the forum

 

What does the door LED do when unable to start?

It could be a faulty relay 109 but doesn't give a fault code.

 

Dont know what d40 code is

 

Are you using Vagcom to scan your car?

Evening

 

Same problem with my 1.9TDi. After reading the excellent post I've replaced the 109 Relay which is the Power Suppy Relay but having the same problem of cutting out.

 

Any more tips please?

 

Am looking at replacing the Fuel Pump Relay and the Fuel Filter.

 

Regards

hi relay 109 did not solve the problem.my machanic said next he will change the camshaft sensor cause that came up on daignostic as d40 or g40 fault code.the red light on door only come on once when ignition is turnd on and it dosent do anything when i start the engine.its getting dangrous and embarassing when it stalls in middle off roundbouts or road.any other sugestions pls.also i thought relay 109 is fuel pump relay.pls correct me if i'm wrong.thank u all.

Hi Z

 

The Actual 109 relay is the Power Supply Relay to the Engine. I Googled the Part Number as its an actual VW part and this was the result. After ordering the part from VW direct as way far cheaper than Frauds, they also confirmed the type of relay.

 

Im now a little confused that the Garage said its the Camshaft Sensor which is causing the problem ???????????? Would this single sensor cause the total power / electrical failure and make it that it wont start the engine then after a little battle start. If a sensor goes either faulty or intermittent then the Engine Management Light or ECU should kick into Limp Home Mode (NO)?????

 

Im not a Tech Head, as more a DIYer using common sense as other cars ive never had or heard of this problem before.

 

I've also been told that its possible that the Fuel Filter maybe causing the problem and needs changing

 

Did u have this checked out at Ford or VW?

 

Regards

109 is the power relay for injectors, when it's faulty will cause the LED on drivers door to flash fast while trying to start.

G 40 is related to faulty cam sensor

Morning Chris,

 

Any Idea Where this Cam Sensor can be located please?

Hi Bryan

 

The Hall sensor G 40 is located in the cylinder head behind the timing belt, if you look behind the oil filter you will see two multi plugs one grey and one black.

 

One goes to the cam sensor the other goes to the crank sensor which is just to the right of the oil filter in the block.

 

Hope that helps

 

regards Chris

As already said relay 109 is the power supply relay for engine ecu/injectors

 

Fuel pump relay is marked 53 in position 3

 

You can normally hear the pump for a second when you first switch ignition on, it only runs for a moment to pressurise the system and sounds like a squelch noise from under the car, if you cant hear anything then it's not working, it may even be a faulty pump or the connections to it.

The pump is accessed through a plate in the floor under carpet middle row of seats area.
