Gatwick is like entering the Savoy compared with Luton airport, now that really is a depressing dump plus they have the cheek to charge you just to drop off passengers, not park just drop off, avoid Luton airport like the plague.

Great to see you and catch up yesterday Jim.

And you :-D Really enjoyed my day!

And another thing about Gatwick, it is so spotlessly clean, even the car parks...

Oh god yes it is awful! Tastes like Satan's jock strap (i would imagine).
Even 8 sugars and loads of milk couldn't disguise the foul taste!

I found this highly amusing. It conjured up mental images of the Sydney Mardi Gras after-party. :shock:

A tenner for parking isn't bad - Sydney airport is dearer.

They must have done a number on Gatwick for the Olympics, it was a complete dirty hole last time I was there, which is admittedly last October!

I always find Costa rough Jim, I think the coffee they use is too bitter. Starbucks is "ok", but you have to think of it as a pleasant tasting hot drink, rather than coffee, though the Colombian mafiaettes actually tell me their coffee is not bad at all.

Well, I have been having fun today...

I may have got somewhere with the Bendix ABS problems on the XM :) Paul (Citroenxm), bless him, gave me ABS two valve blocks at CXM, one good one and one bad one that I was free to play around with. And have I ever played today...

The relay board is sealed but with the use of a sharp craft knife around the seam it can be opened. There's not much in there, just a diode and a relay along with some potentially dodgy soldering. All aspects of the board can be tested without needing to open it and if anyone wants, I can go through the tests.

The one I opened tested fine so I turned to the valve block itself. I noted when I tested the resistance of the five electrovalve coils on the one presently on my car that four read 3.5 ohms but one was much, much higher. I found the same on Paul's duff block, one being sometimes 85 ohms, sometimes 22 ohms and at other times nearly open-circuit or nearly right :roll: Not right.

I checked the good valve block and found all five electrovalves were all 3.5 ohms.

I then pulled the valve block apart cautiously by undoing the four tight Loctited Allen bolts and splitting the block in half. The electrovales can then be removed. They're a lovely piece of engineering..

The valves themselves can be further disassembled by gently unscrewing their caps nearest the coil wires and the coil bobbin lifted out.

Here's a shot of the block in bits:

Image

By looking at the resistance of the duff coil I could make it vary by wiggling the wires from normal 3.5 ohms to open-circuit...

With a craft knife I have scraped away enough insulation to almost get to the coil terminations. Work has stopped at this point...

This is the partially excavated bobbin:

Image

So, it looks like that could be the problem. The ECU must check the electrovalve coil resistances on self-test just as it does the sensors. It looks like the electrovalves may be amenable to repair and if not, a good valve of the right type could be swapped from another duff block or the coil bobbins swapped over or re-wound.

To aid the identification of the duff coil, measure the resistance between the following pins on the 7-way valve block connector and pin 5 of the 5 way valve block connector with the middle plug on the relay board plugged in. A good coil will read 3.5 ohms

Each electrovalve has different coloured wires going to them to aid identification as follows:

7 way connector Pin 1 - Yellow
7 way connector Pin 2 - Green
7 way connector Pin 3 - Red
7 way connector Pin 4 - White
7 way connector Pin 5 - Brown

Although it's a 7 way connector there are only 5 pins and pin 1 is the one nearest the edge.

So, don't throw away duff Bendix valve blocks - they can yield valuable spares ;)

A huge thanks to Paul for making this possible :D

Also today Xac and Danielle popped around for a very nice visit whilst Cassy was having new tyres fitted. I guess they thought my place was a far nicer waiting room than that at the fitters :lol: It made a very pleasant afternoon indeed :-D

As usual Jim you are found in deep surgery :P

You have mastered the Xantia....and no doubt soon the XM :)

Yes, very much so Vince, something I've not done for ages now. Back to my old self really and I'm delighted. One small step on the road to recovery perhaps :) Really enjoyed doing it too.

Baby-steps Vince, baby-steps but that's one reason behind getting the XM. I really wanted to get my teeth into something new and challenging :roll:

The Bosch ABS (2SE, at least) has five-sided internal socket capscrews. An act of bastardry.

Evidently the Bendix one doesn't!

No, just four stupidly tight and Loctited Allen Bolts. It comes apart very easily although on a 'real' job as distinct from investigation I'd like to renew the O rings...

Has your 605 got Bendix ABS Adam?

No, it's Bosch. The relays are built like tanks, but I haven't cracked the bloc open yet as I'm hoping my recurrent ABS fault lies externally.

Have you had any diagnostics on the ABS Adam?

What's the symptoms of your problem?

I ask as a read of mine did indicate a faulty solenoid (electrovalve) if you look closely and interpret what it said...

Drop round and see me and I'll pop your 605 on my TEP92. That's if it has two pin diagnostic sockets...
