Thread: What happened to your D3/D4 today?

I can sorta see the machine fitting aspect but the thing is tapered and the splines are rounded, so I can see a torque vector there that'd lift the socket off the head as it's turned. I just kept pressure on it as I torqued it up.

It's amazing how slight the 10nm torque is on the water pump mounting bolts. My baby air ratchet nearly overtorqued them just spinning them in.

I stripped the washer pump. Mainly I just wanted to see how it worked. Clever little mechanism. The pump is more positive displacement than centrifugal so it can create a negative pressure on the non-operating side which actuates a little sealing diaphragm. The motor was seized up. I assume the shaft seal failed. Common fault for washer pump motors.

My new Eurospare pump arrived today. This weeks job. $45 at AllFourx4 Spares who have a good range of LR service items and less the UK shipping all works out nicely.

Took 10 minutes to do the pump and most of that was removing and replacing 2 screws and 2 push pins from the wheel arch.

Didn't entirely go according to plan. I ended wearing a couple of litres of washer fluid.

There's an intermittent whine now. Sounds very much like the whine from the water pump, but quieter and comes and goes from traffic light to traffic light. I'd never have heard it with the water pump whine.

Only 4 things left. Tensioner, idler, PS pump or fan pulley.

First time poster - Port Melbourne.

I just picked up the Disco Queen, as I have quickly come to call her, a white 2014 TDV6, basic model with what must have been no options, with 210k, 3rd owner.

Being a tech addict the basic head unit functionality needed help.

I decided that the fastest and least destructive DIY route that would also keep the factory menu should I want it (set the clock anyone ...) was to try one of these little units.

Used this CarABC model off of AliExpress for $245 - arrived in 8 days.

(there are several but after searching a bit found this one seemed correct - had to havce the LVDS so the touch screen would work)

Notes:

• It really was pretty simple to install.
• The harness they gave was dead simple.
  
  • I think if I had not accidentally plugged the LVDS into the main head unit instead of the screen unit, which resulted in CarPlay connecting and in music working over CarPlay but no display on the head unit screen it would have taken under 90 minutes but figuring out that dumb error took 2 hours - doh! But this was pilot error.
  
  
• In the end though, wired and wireless CarPlay was up and running 90 seconds after I sorted that out.
• The unit also has Android Auto - not tested but it is in the menu's
• DVD CD thing presumably works still
• Radio works
• Volume knob and steering wheel volume work
• Skip track <- -> does not work from buttons or the steering wheel but if I can figure out how to get into the admin panel I think there is a setting but this is proving a challenge - I will report back if I sort it out -but I can live with this
• You need to turn off the timeout setting in the factory menus so it doesn't take you back to the main factory startup screen
• Press "nav" and boom you have CarPlay or Android Auto
• tools required - the included panel tool, a T20 and a phillips screw driver
• this video is easy to follow although it is on an American version: https://www.youtube.com/watch?v=GzlsC2gur58
  
  • it is also the one CarABC links to with a QR code in the instructions
  • weird fact - I'm American and I happened to notice this shop is right where I grew up just outside of Washington, D.C.
  • this video is also good and he shows popping the center console at 5:13 - this made pulling the side trim a LOT easier - you do have to really pull hard to remove it
    
    • but a little dark so the other one is easier overall to follow https://www.youtube.com/watch?v=Oat1yz1Fuss&t=608s

Open heart surgery in progress - my wife took one look and said she was going car shopping :-D

Didn’t go so well removed half of front end to get at pump.

The Disco 3 pump supplied has a slightly different plug configuration.

Old pump not spinning seized on battery test.

Reassembled front end sans pump and now working out replacement. Don’t you hate that!

Yeah, that's the headlight washer pump. Wrong one supplied.

I put the car in offroad, turned the wheels all the way to the right and just peeled the inside of the wheel arch back. 2 screws, 2 push pins. Didn't have to remove anything else.

I thought this was the front /rear as has two outlets!!

The other one has one larger outlet.

In any case this one is seized. The plugs differ if you look at pins must be something VIN specific.

I went a bit further for access.

Oh, sorry I didn't see the second outlet on the pump on the left. Until I zoomed in it looked like the single outlet headlight pump.

That is peculiar. Microcat pretty much has the same pump across the whole D3 model run.

Made a start on replacing the HPFP, got up to the part of removing the crankcase breather and ground to a halt, cant get that ****er out no matter which way i hold my tongue.
Seriously contemplating cutting in half and JB welding back together, i can puller the breather forward so that the front legs are sitting in the oil filter housing but cant get it out any further than that.
