1.9 DG rear oil sender leak

Hi all - it looks like the oil sender thing on the rear of the engine has sprung a leak. The haynes doesn't say a lot about this one! What's the story? Does it have a gasket? O ring? Easy to get a socket on it without removing too much or is it water pump off? Any help much appreciated..

Must.....resist..... temptation....aaaah, it's no good - the urge is too strong!!!
It's a switch, not a sender. It's on the front of the engine, not the back.
There. Phew, that's better. Soz but it's a compulsion I suffer from.

If will be easier for you to get to the switch if you remove the drive belt
[Pedant mode] note I didn't call it a fan belt or an alternator belt
I am going to express a different view as to the location of the switch. For me it is on the rear of the engine, for the same reason that number 1 cylinder can also be called the right hand bank. Even if I'm underneath looking up [/Pedant mode]

An oil sender is a sender. An "oil sender thing" IS a switch! Heheh..
So if I remove the fanbelt from the rear of the engine I can get a round tube spanner in there with a clicky arm spanner and replace the copper doughnut on the sender?
Not at the van right now, heading there in morning...

Not in the world of VW flat fours, the front of the engine is the flywheel end.

After all that you went and called it a fanbelt
I did it with a socket and ratchet. 24mm off the top of my head
Removing isn't too bad (from underneath), getting the new one started on the threads depends on how big your hands are (from the top)
Let us know how you get on

That must be an air-cooled thing. So when asked to replace the rear main oil seal, you'd remove the front (sorry, rear) pulley? That's a bit rum. Don't often hear people say "just got to bolt the gearbox onto the front of my engine"
Number one's still on the right whichever way you look at it (unless you're inside hanging over the back seat), but back right.

Are we ready for confusion
RMS is always at the flywheel end, but in a transverse engine it will be located on either the left or right hand side of the car, so I can see why you say the RMS is at the rear of the engine.
Move to a different car, say recent Boxster / 911. They have essentially the same engine, different capacities. In the Boxster the gearbox is behind the engine, in the 911 the gearbox is ahead of the engine, in the traditional layout. Number 1 cylinder can therefore be on the right or the left.
I borrowed the following from another site. VW original numbering convention seems to be at odds with the later DIN
, though the industrial engines would comply
From page 395 of the Bosch Automotive Handbook, 5th edition:
Number the cylinders
(DIN 73021)
[ Applies to motor vehicles only. For internal combustion engines for general and marine use, the reverse direction (as viewed looking at the power-output end) is standardized (ISO 1204 and 1205, DIN 6265).]
The cylinders are numbered consecutively 1, 2, 3, etc. in the order in which they would be intersected by an imaginary reference plane. As viewed looking at the end of the engine opposite the power-out-put end. This plane is located to the left when numbering begins; the numerical assignments the proceed clockwise around the longitudinal axis of the engine [ fiqures are referenced ]. If there is more than one cylinder in a reference plane, the cylinder nearest the observer is assigned the number 1, with consecutive numbers being assigned to the following cylinders. Cylinder 1 is to be identified by the number 1.
The figure for a flat engine shows the #1 cylinder is the when looking at the engine from the power output end is located on the right bank at the furtherest cylinder from the power output end.
Convention sometimes plays a part too. Do you refer to the straight edge that you measure with as a ruler or a rule (ultra pedant mode on)

Well, that's that cleared up then.

The front of the engine faces the front of the vehicle hence why No 1 cylinder is the flywheel end and the main bearings are numbered 1-4 from the flywheel, also applied to Renault rear engined vehicles and when the engine was moved to the front behind the gearbox Renault 4/5/16 but not the rear engined Skodas that was an engine turned around from the front engined previous models and No 1 was at the rear.
