Thanks for the replies guys. I am having a mega rubbish time trying to sort this darn temp fault out. I have made a bit of progress but have been otherwise distracted trying to make it look more presentable. How do you rate the CMC spings? I'm a bit of a toss up with mine. Think I might have to get some custom springs with shortened dampers. Seat wise I've got some pretty comfy capitan seats currently but still very undecided. I will try and update with actual updates Saturday. But for now have this.

I've been pretty poor keeping this up to date. Photo bucket seems to have become super rubbish lately which seems to make photo updates a little bit annoying. Anyway. I had planned to use the T4 for a run down to the West Country, I tried my best but unfortunately there was just too much to do. I moved the van recently and t become apparent that there are a lot of things that need tending to with this van. However before I get onto that, let me update this in regards to my engine temp problem. So, as I showed earlier, I replaced both temperature sensors, gauge still doesn't work. With that I decided the dash had to come out. To remove the dash I had to pull the wheel off. Could this be the possible cause to why my horn doesn't work? Broken contact ring. And what appears to be a damaged, although could possibly be repaired with a bit of solder? Anyway, back to the dash. Looking at this, I speculated that the dash hadn't been removed before. Yuk I then split the dash up following this link here. www.vwbooks.co.uk/vw_info/t4_gauges.htmI found the 6 pins at fault and to my surprise I found that someone had been here before. Someone has already resoldered 3 of the pins. I thought whilst I am here, I might as well do the other 3. First attempt at this kind of thing really. I did the top 3, someone else did the bottom. I threw the lot back together, put it in and guess what? Still doesn't work! Thinking about it again I probably should have soldered the bottom again, it may have deteriorated since being repaired, but I don't want to damage the board. The other option that I see is perhaps throwing a different dash in. This is something I have wanted to do for a while actually as my clocks have a clock and speedo, I would prefer a speedo and rev counter ideally. Does anyone know what other dashes fit in these and work? Ideally with a rev counter. There is an odd looking wire near the sensors which could be a contributor, no idea what it does though but it has been fiddled with. Does anyone know which sensor feeds the gauge, the 2 pin or 4 pin? Also, does anyone know what the resistance this should show through the heat cycle? Also, I think this little feature is pretty cool.

Electrical gremlins almost seem to be part of t4 ownership, mine has a non working temp gauge, a starter that doesn't like cold mornings, possibly an intermittent battery drain/faulty ignition switch, the non working screenwash was a missing relay. There's a wealth of information about the faults and how to cure them on the t4 forum Mine also suffers from badly done, filler covered scars. Ttfn Glenn

Ah mine has a good 20kg of filler in there!
This era ignition switch is usually a cracked plastic housing which results in the contacts not... Well, contacting. I had the same problem in my 944, a mate in his mk3 golf, from what I understand they're all of the same design. A £5 part, but requires the steering wheel and steering lock off.
I've tried all of the suggestions on the T4 forum but we seem to have struck a blank. I am hoping that a new set of dials may sort the problem. I have as you can see speedo and clock, where as I would prefer a Rev counter. I am currently investigating potential replacements.

The voltage reg problem on the clocks is a common problem area, but the solder you need to reflow is in the back of the temp gauge itself, done a fair few in the past.

Thanks for that link Glenn, I was actually reading through that last night but didn't get as far as the Passat section. I did however get this. They're early corrado clocks and after checking with a work colleague who has a 93 G60 he confirmed that they are cable fed and that they can be made to work with the MPG feature... Not sure I really want to know that to be honest! Says they were shipped out yesterday, so hopefully when they arrive they will solve my problem.

Hey buddy, do you still need trim bits for this? I am almost certain my mate has one decaying in his yard. I can ask him if you need anything? Cool van btw, I have an eye on a day van conversion but vw are to expensive for me!

Hey buddy, do you still need trim bits for this? I am almost certain my mate has one decaying in his yard. I can ask him if you need anything? Cool van btw, I have an eye on a day van conversion but vw are to expensive for me! YES!! Very much yes! I will drop you a PM in a second. The idea of a day van I think is awesome. I end up with surfboards, kayaks, fishing rods and all sorts crammed into my truck, where as the van offered a load of space, comfortably, plus I think the dogs will enjoy it a bit more. The van is fitted with a tow bar so I can still tug the bike on trailers and jet skis. I agree. VW is incredibly expensive. I had a vito which was awesome, and the Renault Traffics, Vauxhall Movano and similar sized vans offer excellent value for money in my opinion. I keep looking at the newer Vitos. Some remap to 180hp, incredible MPG and come with a load of features, 6spd box, air con, electric packs, sat nav. Makes me kinda wonder why I got this! Then I remember it was incredibly cheap.

PM received! :-) I will pop down there tomorrow and have a word,see what's what :-) sure its there, it was beside a nice range rover classic 3door V8, hence why I spotted it! Amazing what lurks on unassuming industrial estates.... 63 pontiac grand prix nearby.
The vito sounds more luxury car than van to me! There is something about the t4 vw though, i think it maybe looks quite 'traditional van like' if that makes sense? Still silly money,so well done on getting one reasonably, Sounds like it will be a useful peice of kit when ready! It is also interesting to see how different people treat their work vans :-P

Thank you very much! That's the part I need most of all. Well, along with a few other bits. I might actually send you another PM with a few more bits actually hah.
Yes, there is something strangely alluring about the T4, I think it may be the boxey, Rubix cube, retro square look to them. I like the way there seems to be so much variation between them. Plenty on fancy 19" wheels with Bentley style trim... Then there's the banded steels and camo seat cover brigade.
A friend came to me the other day actually saying he was in the market for one but didn't want to pay £6,000+. There seems to be a few reasonable ones out there if you check daily. All ex work vans or caravelles (which are less common) but some are reasonable. Plus I guess it gives you the option of fitting it out exactly how you wanted rather than how someone else has made it. Got to confess, I am a bit lost as to how to lay it out. Guess I need to get the thing road worth first!

Any pointers? I need to do the same to my 94 1.9d Thanks for the info, that's the first time I have heard mention of that. Could you give us any more info? Thanks again Take the clocks apart and reflow the solder pads - failing that, pop just the temp gauge in the post and I'll do it for free. I recognise your user name, Caddy Forum or somewhere? Yes, caddy forum, T4 forum, retro rides, GTD forum, pretty much anywhere really I'm like a plague. Don't go the 19" rim route - ruins the ride and looks bobbins. Oh and the T4 is expensive for good reason, when you come to sell you wont loose a lot if anything such is the demand, my first one I owned for 4 years and lost a fiver, this was well before they became really popular. There are three terminals on the temp gauge, +12v, GND (ground/earth) and signal. If you short the signal to the gnd the gauge should go to max and the led flash - if it doesn't the fault is in the gauge unit, if not the fault lies elsewhere - either the supply to the gauge (check for 12v) or the wire to the sender (should measure a few hundred ohms between the signal connection and earth. Blue looks good, graf paint? don't buy the cheap springs, hey are just not up to the job especially if you go for a camper conversion, you wont need different (shorter) dampers, the HD sachs dampers are good upgrade and about £150 for a set if you look around.

Thanks for the reply Reg. I've tried it on the dash backing, however if when I throw the corrado clocks in I still get no gauge movement I think the problem may be in the sensors or related wiring. Which sensor feed the clock, the 2 or 4 pin plug?
I knew I'd seen the name somewhere. Would have been caddy forum.
Thanks for the offer of repair. If I totally balls it up I may well be in touch.
The van came to me with 18s on, with a 45 profile tyre which I can only bet will take about 100 miles before it gets on my wick and they get replaced.
There was some lowered springs and dampers, CMC perhaps or T4-R-US for cheap, but the chaos inbox is full annoyingly.
I saw you was looking for some lazer cutting. Drop me a PM if you fancy, I have access to a pretty large lazer.

2 or 4 pin??? Are you talking about the sensor connections??? Normally it's 2 x 2 pin connectors or 1 x 4 pin You have two sensors, one sets the glow plug time the other drives the gauge - short out the gauge wiring to earth and the gauge should go to max.
The laser cutting is a project for work, however as I've handed my notice in and only have 8 days left, I may not be arsed.

Thanks again for the help. Yes I've got a two pin up top and a 4 pin down bottom. My van is a petrol, 4cyl 2.0, so a little lost now as to why it's got the two plugs. You can kind of see it in this very bad photo. I'm guessing that it's going to be the top 2 pin plug that feeds the clocks so perhaps I should start by shorting that out. Ah fair enough in regards to the laser work. I thought it was to make something better/faster/look cooler.

Page 5 on here www.1946vw.co.uk/vwbooks/vw_info/T4_pdfs/T4_Base_Wiring_from_May_1999_on.pdfwould suggest it's the YEL/RED wire at the sender - do you have one???, if you short it out there may be a fault with the earth brown wire so I'd always short it to a metal part of the engine to eliminate the earth wire as a possible fault. I think you have a more serious problem with those five strange thick black wires that are fitted - they should be solid pipes containing diesel.
