3b s2 coupe resurrection

[andy10v]

Forgive me, for I have sinned.

Bought my first diesel, an 80 1.9 TDI.





Does anybody know where the coolant temperature sensor for the gauge is?

Got a few wee bits to tidy, but seems like it will do the job nicely. It does mean I have a surplus ABY coupe now though

To me it looks like it could be the blue plug on the water outlet on the right hand side of the fuel pump.

[andy10v]

I was eyballing that one, it goes into a fitting in a large coolant hose. Just wondered if there is one for ecu etc as I am not overly clued up on dag dags.

[TimE-J]

If its a 4 pin plug then IMHO that would more than likely be it, again though I'm not 100% sure.

Funny looking spark plugs it has

just gone out and checked my 1.9 tdi mk3 and it has a 4 pin plug in that position so I would say that that is the sensor.

[andy10v]

This blue one is a two pin (1995 80 1.9tdi, so the later ecu I beleive)



Another electical thing in the water on the back of the block (pipe heads for the heater matrix)



I presume this is the egr setup that is often gets blanked off?

Except with you lot it will be pistons and con rods, and then a shell or something

[andy10v]

Does anybody know what the 80 1.9tdi gearbox ratios/final drive are? (or where to find then?)

Does quattro and fwd use the same abs setup?

[andy10v]

Also where does the engine wiring loom terminate? Is it at the ecu or does it go across the dash?

Drilled and tapped the turbo hotside, stud is m10x1.5 so progressively drilled up to a 8.5mm hole. I don't have a pillar drill so vice and hand drill, snapped one small drill bit which was a PITA to get out, ended up drilling 3 tiny holes around the snapped bit, and was then able to remove it with tweezers and continue.



Tapped


Then opened the top of the hole to 10.5mm for the 1mm shoulder on the stud


And installed


What is the installation procedure for the stud?

I bought a C spanner to help with turbo removal, is there any other special tools needed?
