This was more fun when Jardo wasn't here.

Nobody ever posted anything, how can you say that?!

I can sort it if you want Robin, just get all the bat crap and moth wings off it. That's grim.

Not sure if I've got space to do it up here though, probably best for you to throw me £20 for fuel and do it at yours.

I'm actually with you on that one Jardo, even as someone who know's you away from the forum, so is more interested in your going's on than most of the other guys reading this, I'd still quite like it if this thread could leave out a lot of the discussion our little 'friendship group' has with each other. I think it'd help the thread get back to being a bit more varied. I like it when other people post in here, and there's been a few awesome cars posted up (nice E21 if I remember right?) that have just been a single post followed by pages of our ranting and the owner never bothering to post again. We're missing out on interesting stuff because of it. I think having a thread that any arguments/in depth discussions can go over to in order to continue's a really good idea. It's like that HID thread being separate, it's meant there isn't a 3 page argument about HID's clogging up this thread further.

In fact thinking about it there used to be the VW thread, the Mini thread and the french cars thread, maybe we should start a 'VAG' thread for all our little 'groups' rantings?

Why not just make a group on Facebook then? You'd have better mobile support, non-TF members could contribute etc.

My issue with facebook is that everything moves around to fast, I can't keep up as soon as I spend a day or two away from the computer, and then I can't be arsed to catch up. Forums are nice because people don't voice their every insignificant thought, and they have some restraint because it's truly public, so thing's are all a little slower and more thought out.

Anyway, to keep it at least vaguely on topic, I spent last night looking through Passat wiring diagrams and I think I've made some decent progress towards deciphering the wiring I'll have to do to get the 20vt to run in the Scirocco. I'm still a little stuck on the immobiliser as they Haynes I've got doesn't seem to make much mention of it. Does anyone know where the immobiliser's receiver is actually located on VW's? (In particular in a 1999 1.8t Passat sport.)

A facebook group wouldn't be any faster than this.

On mk4 platforms, it is in the black plastic collar at the end of the ignition barrell, literally right by where the key slot is. 1 green wire, 1 black (was on my a3 anyway). It then goes back into the clocks, where the actual immobiliser circuit is. Most people with engine swaps just do an immobiliser defeat/delete though...

Ah cool, thanks for that George, that's good news because I've still got the whole column and the key. Were the wires spiraled around each other? There's a pair matching those colours coming from the clocks that Haynes have cunningly left those off the diagrams. That's easy enough to sort then, I may actually use the immobiliser, as I've got aftermarket central locking which has space in the key for the chip and that ring looks easy enough to fit onto the Sciroccos column. If not I could hide the key/ring somewhere in the car, but somewhere I can get to so I can remove the key if I leave the car anywhere dodgy. I don't really want to have to send off the ECU as I'm in a bit of a hurry to get the car back on the road, plus the extra security's a bonus, for the sake of 2 wires why not, I'm using the Passat clocks anyway as mine are shagged.

Oh, it's a Bosch Motronic M3.2 management system by the way. (Well, the ECU's part number comes up as an M3.8.2, but I'm guessing the '8' just denotes that it's a Passat system?)

Yeah, Robin, they are twisted together for data screening.

The ring IS removeable; I took mine off, and glued the transponder chip onto it, and stuck it in the clocks (I had no ignition barrell. I started the car with a push button, and had the ignition switch under a military style flip cover. "Security" came by the form of a motorsport battery kill switch (not exactly secure, but it was kept in a locked garage when I wasn't using it...and it was so raw to drive, I'm pretty sure anybody that nicked it would've returned it pretty damn quick haha!)

Jardo, he probably will, but I remade the WHOLE loom without using a wiring diagram (ever seen the amount of cabling in a bare a3?! (without the dash...90% of it is behind there)) Custom looms take a loooooong time! Plus, I did mine for want rather than need, hence the "slow" progress!

Word Seamons. Every time I pull the lower dash pad out a bit of me dies.

Just booked my mate into Niki's to get his Mk5 TFSI mapped. Now he's trying to chicken out. Need to peer pressure him into doing it, I let him drige my A3 and he agrees the extra power is worth it but he is being a girl.

Cool, thanks. That means I'm done with deciphering the clocks now, they don't look too bad to get working really. My main issue now is that the engine loom I've got is the horrid type where the first meter or so of it is encased in foam, meaning it's a pain in the arse to trace any wires through it. I may have to try and get a loom with the engine, because this is a nightmare. The connections between the cabin and engine looms all go through it before going back to the ECU, bloody modern cars!

Yeah, like you say, making a new loom's seriously time consuming, especially with modern stuff. Given more time I'd love to re-do all the wiring in the 'rocco as there's some not ideal repairs in there at the moment, but I don't think I'll have time to do anything more than remove the worst of it. I'm wanting to keep all the new engine stuff separate from the original wiring, just taking feeds where it has to, so I can tackle the cars wiring later when I've got money for a second car and somewhere more permanent to work on it.

Edit, yeah, I pulled it out of the column just now, easy enough, the main concern with using it in the 'original' place on the Scirocco is whether the original ignition barrel's narrow enough for it to fit around. If not I'll probably wire the Passat's ignition barrel into a hidden location as kind of a kill switch/cut-off so I can remove it if I feel the need.

The worst bit of the loom is behind the glove box. There's a good thick wrist-sized bundle of cables going though there. I reduced that to about 10 cables.

There's so much unneeded bollocks in the loom :P

There's really not that much in the clocks once you get rid of the bulb monitoring stuff, abs sensors, door sensors etc etc.

I had that foamy stuff too...its a b*****d! I pulled the foam off, but under the foam there's still the materially loom tape, which is REALLY sticky, and leave the wires in a right mess!

Wasn't impressed with the way some of the cables were jointed from the factory, looked a right bodge!

Yeah, some of them seem to be spliced by just going into the same end of a crimped connector, and then some heat-shrink stuff stuck over the connector! I guess in the long term it's more reliable than soldering, but it does look a bit crappy! I think I'll see if I can get away with leaving the foam in-tact, it'll hopefully keep things pretty tidy, it's just a pain working out the wiring to the connectors between the engine/cabin.

I drove along a new bit of the ring road today wondering why there wasn't any traffic. This is why:

It just erm... ends. The other part of the ring road also ends in a similar fashion, they can't afford to connect it up. I love this country, it's so silly. And the fact that it looks like a huge penis just makes it better:

Haha, yeah! A few of those joins had different coloured cables in them too, very messy!

Your some kind of electrical engineer aint you? I'm not looking forward to doing my honda>mini wiring but i guess it should be simpler than the audi.

will adding castor make my suspension raise up when i turn.

ie when sat still i can tuck my tyre under my arch and sit pretty much flush, then when i come to turn it will raise and clear the arch?

just thinking at the moment. the e36 already does this but just not enough with my rolled(not flared) front arches

It depends how much of a scrub radius you've got. As you're running pretty low off-set wheels (if I remember right) it will likely make the inside wheel raise slightly but not the outside one, although it may raise marginally because of the other side lifting. It'll only make a very marginal difference though, the amount of castor you'd have to add to make any noticeable difference will ruin how the car drives, heavy steering and extreme snatch-back/self centreing/tram-lining.
