Osysis (Peter) asked me in a private message where to find the X308 AC waste-water drain tube, as he thinks, his is blocked.
I was just about to send him 3 pictures, when I realized that it does not seem to be possible, to add pix to priv. messages.
Hence, this brief new post here:

So I had a look at my X308 and I think I found it on our RHD Australian X308s:
I think it is just right of the passenger side (left) glove box behind the carpet:





I pulled that grommet-like tube-end out of it's hole carefully to avoid tearing it.
There are 2 easy to remove plastic nuts on the heat-shield under the car covering this area.
Removing those, however, does not bring you any further. Also, I do not see any purpose in somehow removing that heat shield.

You need a lot of finger-strength. to then get that grommet-tube back in again...

Cheers

 

So...this drain tube, if blocked, could not be cleared with a wire coat
hanger? I had a similar situation on a BMW and that is the solution
that worked for it.

 

Randy, the A/C drain tubes aren’t visible (or accessible) from the underside of the car and that’s why a coat hanger wouldn’t work. Easily accessible as noted in the above photo, it’s still quite easy to unclog the drain tubes.

This is just *another* reason why I prefer this vintage of the XJ platform. The X350/358 succeeding the X308 has a completely inaccessible single A/C drain. I’ve had to unclog 2 in the X350 platform and it’s a huge headache. The X150 07’+ XK is accessible once the transmission is out. 😂😂 I’ve done dozens of those.

 

"Hello, customer? Yes, we have the estimate to clear your clogged drains. We have to remove the transmission."

I can only imagine how that conversation goes...

 

That's very interesting. I wonder what the engineers were thinking?

 

Randy, I was asking that myself many times over at many occasions.
I worked as engineer in the X400 team in 1998 in Coventry.
Back them I did not know all the little Easter-egg surprises, Jag build into their cars, otherwise I would have had the perfect opportunity to sus this out...
But the X400 light-switches, for which I was responsible (plus some other switches), are all straight forward.

PS:
Just another example of "what were they thinking"...:
I am currently having the little shaft bits removed from the diff of my X308, as there was an oil leak.
I think it was the o-rings onn the outside of the bearings...
Barrat give the P/N as JLM2051. Sadly, it is kind of frequent that Barrat lists wrong P/Ns. The correct P/N is JLM20451. I had to call Jaguar to figure that one out - but here it comes:
This o-ring is most likely NOT for my X308, because this P/N is only for use up to VIN 846051. AFTER THAT there is no longer a separate O-ring available: It would be required to buy the whole bearing, I I don't even want to know, how many hunderets of $ that costs. If I were to order it anyway, just to see, it it fit or not, that would be AUD$60 per O-Ring - what a bargain...

I found a solution for myself, but not thank to Jaguar.

Another think I found out at the same occasion: Jaguar stopped some time around the X300 V6 to supply with their parts the information regarding the dimensions (of e.g. bolts and O-rings, cause that is actually all I need for that O-ring I am after - I just measured the one (deformed) one and had an educated guess...

 

They'll be thinking "That saves half a second on the production line or costs 0.2p less to make". Once the car is sold they don't care, it's all about making them as cheap as possible to maximise profits.
