Just bagged myself a 2.5td estate elite. Loving all the extra gadgets that I didn't have in my cd td.
Anyways there are a couple of electrical gremlins but I'll get round to sorting them out. So not sure of I'm being a dope and don't know how to get the cruise control to go on or if it's not working.
Can someone give me a quick run down of how it works, thanks
-
Press the button on end of the indicator, one with nobble. Press it again goes faster. One with dimple slows the car. Big one underneath cancels it.
Along with clutch and brake pedal, this also disables cruise.
You might want to read the manual though :y
-
Will give it a go in the morning. Thanks.
-
Petrol models need you to be going 18 (iirc) mph or faster for it to work, unsure if this applies to diesels, but its something to be aware of when testing.
-
Also touching the throttle temporarily, it remembers the speed you set it at, and allows the car to return to this speed after you have released the throttle pedal. This is intended for overtaking. Also touching the brake pedal cancels it.
Tip is it takes a second or two to kick in. I find best to hold the throttle pedal where it is, touch the 'on' button, wait a couple of secs, then release, otherwise you get an awkward surging sensation as the comp reads the speed, you slow by say 3 mph, it actuates the mechanism to hold revs appropriate for the original set speed, realises you're doing 3mph too slow, then gives a little stab of throttle to bring you back up to the original speed. Slight 'bunny-hop' sensation which can feel like you're on a driving lesson.
Also you can use the 'go' button as a throttle pedal. Just hold it in (over 18-ish mph) and the car will accelerate, in an Auto this is particularly delightful experience as you've no gear changing to worry about. I find the way it speeds up is neither too slow to be glacial/boring, nor make the instantaneous fuel consumption drop to 7mpg, as it does when I use the loud pedal!!!
-
As others have said...comes as second nature after a while ::)
-
DBG, thanks for that "throttle-holding" tip; I never knew that and I've used cruise control for years!

:) You're welcome. Personally I love it, and I use Cruise all the time, but being able to move from a theoretical 20 to 120 mph with your feet comfortably nestled into the carpet, by operating a single button feels like something very space age to me. I also love the way the throttle pedal actually moves down as you accelerate, just like KITT in Knight Rider!! :y :y
-
Tested and not working. Like mentioned there's a couple other electrical gremlins including memory seats working but heat not.
1st port of call will be the fuse box as I discovered a couple of fuses in a pocket so fingers crossed it's an easy fix.
If not a fuse any suggestions?
Thanks

Clutch switch, brake switch, stalk... to name but three possibilities ::)
-
Being a TD, I wouldn't mind betting its had a new indicator stalk... ...and the wrong one fitted.

That would be my first call as well, the 2.5TD's use a BMW Resistive Pad type switching against normal on / off contact switch as used in the normal VX Engined Omega's.
Even if its the original type, they get tired over a while, or as TB's states its been replaced with a VX type one.
-
Could be the case it's been replaced as it's real crisp and clicks real sharp. What way can I tell for sure that it actually has cruise control?
If it doesn't, is it much of a job retrofitting it in?

The TD is one of the few Omega's where just fitting the correct Stalk wins you a Cruise Control feature irrespective of model spec, as its already enabled in the ECU (in almost all cases).
If you have a DVM or Volt Meter handy, you can disconnect the Stalk plug and measure the Stalk across the two wires, fairly sure from memory there a resistive value even in idle mode, pressing any of the stalk buttons will change the resistive value, where as a normal stalk your be measuring open / closed switch contacts.
Fairly sure I did a 'How to check your TD Stalk is working' thread somewhere in FAQ Section but can't seem to find it now.
-
First check if the trailing wire from the stalk is 2 or 3 wire (just remove upper cowling)
:)
-
I fitted it to my 2001 cd cause i had it in my 98 cdx but now i always forget its there and never use it ;D
-
Removed the plastics round the steering wheel there this morning along with another heap of stuff. Anyway this is what I found. All wiring seems all ok and plugged in ect but I know nothing about wiring so have a look and tell me what yous think.

Looks 'normal'. May be corrected on this, but the [what looks like a] single wire with foam round it is the cruise control one? This based on owning an Omega with non-functioning cruise, and upon inspection, snapped wires here. The rest of the stalk functions worked fine.
Three wire on petrol, two wire on Diseasel, I think. :)
-
Bad angle picture. Need to double check. There's 2 wires there. Maybe 3
-
It's got 2 wires for the cruise control. One is white/light grey the other is a light blue.
Any ideas what to check next? I've a multi meter at home but would need talked through what to do

If it won't switch on and all else seems in order, you need to renew the clutch and brake switches as one of the might be sticking which will prevent the cruise from engaging :y
-

or at least check its adjustment. I once fitted a new brake switch (wouldn't come out of Park) and lost cruise unless I lifted the brake pedal. Another click on the switch sorted it. ;)
-
If no good on the above (as it costs nothing to check) my next port of call would be another switch. Depends, I've got a few guys round my way that have odd old Omega bits which I m lucky in that I get charged a pittance, or even given hem for free. There must be someone who has a spare on here. To be honest, even f it turns out not to be the switch, worth having a spare one anyway, as they're on the 'known failures at high mileage' list.
I'll look in my spares boxes, as a TD two-wire one is no use to me, and have no desire to return to Turbo Weasel ownership in the future :y
-
My '99 TD CDX has cruise as standard, therefore as Elite, yours must have had a failure if its a new stalk. :y

If you've got a TD 2 wire stalk fitted, measure the resistive loop of the stalk first, this tells the ECU a Cruise Stalk is fitted, as without this the Cruise wont work, no matter what button you press.
Disconnect the Stalk and with the Stalk isolated, measure the loop resistance (across the 2 pins) you should see a loop resistance in the region of 670 ohms. Then by pressing each button in turn you should see the following resistive changes -
Normal, Idle, loop resistance = 670 ohms
Press Cruise On / Speed Increase = 67 ohms
Press Speed Decrease / Resume = 167 ohms
Press Speed Reset / Cruise Off = 1.6k ohms.

Thanks very much all of you guys. Will try the multi meter and check the adjustment on the switches on pedals.
Daft question agsin as it's an area I've never had to poke at but is the switches on the pedals easy got at of is there a certain degree of stripping needed?
My td estate is in beautiful condition and just want to get these niggles sorted. Have everything working as it should.
Oh yes and get my lsd fitted but that's another story....
-

Fixed that for you. ;D

It's 2 wire. Will check resistance then pedal swithces
:)

Cheeky bugger. It's the lsd out of my old silver saloon. Never let me down. Will get a wee thread on the go for that when I start stripping and painting ect

Just done this with help from my neighbour. All readings are as you mentioned.
Take it the next port of call is the pedal switches????
-
Got a good poke about the switches. Christ there hard to get at.
Anyways I know bugger all about adjusting them. But could see they were all plugged in. Anyway found this on my travels neatly tied up in a knot out of the way
Any ideas what it is?? And could it be something to do with the cruise control?? Like I said the 3 switches on all pedals are plugged in.

That's either telematics or traffic master related ;)
-
Thankfully the traffic master doesn't do anything when pressed so obviously disabled. So what's this telematics thingy-ma-bob?

TM Network was switched off years ago, Telematics is a Nokia Phone Unit add-on to the NCDC HU's that lives in the Glove Box, which I'm fairly sure yours wont have before you ask.
Out of interest is yours an Opel or Vauxhall? and what model flavour is it?

Vauxhall 2.5td estate elite year 2000

Pre or post facelift :-\

It's a facelift
