VCU is a good first check.
Although a cheaper check though harder check, I would prefer to do is the auto-adjuster on the drums at the back. the spring that holds them in the right place and allows them to work without adjusting to the max each...
Thank you.
Have since removed the master from the car and "un-built" it 😅 Following removal it looks like the seal for the fill under the actual container was very cracked leaking and just falling to bits, some other seals were good and others...
Ever since I got my 2003 TD4 Sport, the turbo lets out a growl or a rasping noise when it is working, say when the car changes down on a hill and the turbo comes in again.
At 53k miles, I didn't think it was a turbo bearing, now at 68k it has...
Check main ground from battery to chassis for good contact and ensure the crimp lug has no corrosion ,check ground strap from engine to chassis and gearbox to chassis and all subsequent earth points and ensure you have your DVM on dc voltage
Have you confirmed the battery is charging.
Could be a bad earth, when it gives the fault test battery voltage plus to minus and also plus to earthed points, ie the engine. Should all be similar readings.
Do the sensors plug in independently to the module? If so does the issue follow the sensor or where they are plugged into. Try just one sensor at a time. Maybe a damaged cable that's picking up interference, you could try oscilloscope on the sensors
Ah I suppose key 1 and key 2 are completely different inputs so you can connect them to two different resistor networks. I don't know why I didn't think of that.
That's put better than my explanation! Spot on. The other wire, key2, to the head unit could give extra functions by doing the same. Not sure where the settings are on the head unit but I imagine you can work it out!
Thank you for replying.
What you said worked.
Just to be clear:-
The two wires that you cut come from the steering wheel controls to the back of the factory head unit plug.
You earth one of the wires to chassis.
You connect the other wire to the...
The 2 above pics, top one shows which 2 wires cut from the steering wheel. Meter between them and the resistance will change with each steering wheel button.
The second shows one of the above wires to earth and the other to the input on the...
Use either 1 or 2, from memory it's the resistance to earth. May need to earth one in the loom. I can check tonite.
Then there is a menu to learn what function is what. Can use long press for different functionality.
If desperate, pic 2 above shows the little clip that holds the brake shoe in, one for each shoe, cut them off at the back( might not have to do this) and use a puller to remove the hub. Might only be a small lip but shoes could be dragging. The...
If its the fl2 then I think there is a tool to access it easier. Don't over tighten it. If you move it the it's bound to be in the way of something else. With practice it should become easier to to remove and not get so much oil down your arms...
