While a joint is ok, I'm not sure a reputable garage would use one. By the time the joint was made a complete pipe could be installed. A pain on axle stands to get in but probably easier on a ramp.
Depending on level of security a money tin might be ok.
Leaving out of sight isn't always best as anyone who has access to the car,eg mechanics, may find it and you possibly wouldnt know straight away.
There is the option for a second lighter for the rear passenger, the cable could be there under the cubby box. You can then easily fish cable where you want it, even inside the cubby box.
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!
