Thanks for pointing out the problem!
Link now amended on original post but also added below.

I basically copied it from a thread I have posted it on in another forum - the link was then effected. This one should now be fine.

Omega General Help / BWM Diesel 2.5 TD: Ticking Noise (inc. Footage of
« on: 23 August 2006, 19:51:39 »
Hoping someone can help me a little. My Omega has the BMW 2.5TD.
Firstly, this is going to be a longish post to give full background so apologies for that in advance.
Background
Basically I have a strong 'ticking noise' on idle. When revved to say 2000 rpm or above the noise seems to be considerably reduced / goes completely. I've had several suggestions such as Hydraulic Tappets, Timing chain / Tensioner, Injectors etc.
My question is, are these engines usually 'quiet' (subjective I know) at idle? I know all diesels are louder than their petrol equivalents - but do they usually suffer from a specific ticking / tapping? Car is a 99, T Reg with 124k on clock.
I have had hydraulic tappets changed for new ones which didn't cure the problem. I also changed the Water Pump as a precaution as I understand these are a weak part.
A few days ago I popped into a BMW specialist in Manchester who first commented that "these BMW Diesel engines are usually bullet proof" (I know some people disagree about this engine). He said that he has worked on these for years (in BMW cars obviously) and not generally seen too many problems. He had no explanation of what the noise was.
I have also been to a diesel specialist who said he has done a reasonable amount of work on these BMW diesel engines - again I was told they are 'very durable' - which were his words? Anyway, it was suggested that this could very well be an injector and to consider having them overhauled as my car has done 124k. He thought an injector(s) may be sticking OR leaking too much fuel past the nozzel(s) i.e. leaking fuel as the piston is on it's way back up causing the 'tapping noise'? (not sure if I've explained the second bit right?).
After doing some ringing around I can get them overhauled / a re-conditioned set - exchange - for £16.50 each + VAT = £116.33 for all 6 including VAT. Is this a good price? I will gladly pay the money if this is definitely what is causing the noise. Today I noticed the noise was very intermittent, unlike usual when it is constant - engine sounds great (for a diesel) when the noise is not there.
Would really appreciate advise as the car runs perfect in all other ways and it's spoiling the car. It has been like this since I got the car about 6 - 7k miles ago. I wouldn't say the noise is getting any worse either. Tends to do it less from cold (although still there) but worse when engine is fully warm.
Footage of actual Noise
See attached link where I have tried to capture the noise by using the movie function on my digital camera. Ignore the footage itself as I needed to be in the drivers seat to rev the engine (no one to assist I'm afraid) and so ended up pointing the camera down towards the ground to get the best sound. You may need to turn up your volume to get the best sound effect from this clip, but the noise captured is a fairly good representation - maybe listen to it a few times to get best feel for the noise.
Only lasts 20 odd seconds - hope this works!

Anyway I'll see what people in the know think on here to the noise first.....particularly interested in peoples comments who have one of these and can compare with theirs!
Thanks in advance.

Omega General Help / Re: Retrofit Cruise Control Problem on 2.5TD
« on: 11 October 2006, 14:46:35 »Quote
Quote2.5TD stalk is 2 wire.....the standard stalks (i.e. petrol) are 4 wire as they have a supply line and 3 return lines, one for each switch.
The TD stalk works with a single wire thanks to the fact it has resistors in it so a different resistance is presented across the two wires depending on what switch you press.
NO 2.5TD ever used the 4 wire stalk....its simply an error on how the parts department is reading/interpretting the info.
The correct part number is 9181012 (as confirmed by my friendly and compitent parts manager)
Many, many thanks to both you and 'The Boy'for help in clarifying the correct part which I have now correctly ordered. It is unbelievable how what should be the simplest thing can cause so much confusion and hassle. Added to this, the ingnorance and incompetence of some vauxhall parts departments (and service departments come to think of it) leaves me in no wonder why vauxhall get slated for poor customer care by many. It's a shame because some of the dealers are quite good and cars are great in general.
Thanks again. I will post when I have the part to confirm that it works - should be here tomorrow.
Confirmation that I got the Cruise Stalk today - part no. 9181012 - and it does indeed work perfectly. This is indeed the 2 wire switch.
Massive thanks again to Marks DTM Calib and The Boy for excellent information.

Hopefully someone will correct me if I'm wrong, but 2.5TD cruise stalks are 2 wire, all others are 4 wire...
Right.....maybe getting somewhere! From your information there are three part numbers listed.
9181014 - this is the one I have = 4 wires, this is what vauxhall have listed against my car reg number, but doesn't work. Could the final number in this code - 4 - refer to number of wires?
90460318 - this part I'm now told by a different dealer is superseded by the next number.
9181012 - leaving this final one which I have now ordered for tomorrow. Again, could the final number in this code - 2 - refer to number of wires? Hopefully this one will work and presumably is the 2 wire one?
In answer to your comments, some TD's must have a 4 wire stalk (9181014) - although it doesn't work on mine - as this is listed against the 2.5TD alongside 9181012. Would be interesting to compare these part numbers with those listed against petrol models.

Soz, only have same tools as dealer for identifying. Ask the dealer to call Vx Tech services to properly identify...
Don't suppose you are local to me?
No, I'm on outskirts of Manchester.
Do you reckon this will work with one of the other stalks listed?
FAO anyone who has done this to a 2.5TD
Could you have a look at the id sticker on the underside of your cruise stalk - there should be 2 letters which will probably be one of the following:
BM
AJ
BK
This would help me loads.

Hmmm, I posted that in a hurry last night without really looking (hence posting all of them for 2.5TD).
What is your engine number (should be on DLVA V5 logbook)?
Engine No. is 30829118.
Just having issues with Vauxhall dealer as they are saying that unless I know the exact part no. they are not willing to order as both of the other no's are not stocked by them. They are adamant that the one I have is listed for my car when quoting the reg no.
I think another possible way of ID'ing the stalk is from the id sticker on the underside of the stalk. The one I have is BM, the other two, 90460318 is AJ and 9181012 is BK.
Are you able to help any further in identifying the correct one?

So, if I am reading your info correctly (apologies if I'm being thick) there are three different part no's (inc. the one I have - 9181014). The other two are 90460318 and 9181012. Any idea which of these two it will be? I think my engine is X25TD, but that doesn't help as they are both listed for this engine.

Clutch switch can be tested with Tech2, I would like to think that dealer knew how. Clearly stupid.
No light on dash.
How much was new stalk?
Thanks very much for your quick reply's. You are right about the standard of the vx technician - could tell he didn't really know how to use the Tech2 in detail - but to be fair he was doing it for me as a favour - I managed to speak to him in the car park - explained that I had just bought a new stalk from them and could he enable it for me (without the £40 odd pound associated charge)!
Anyway I think your comments seem logical regarding the the 2 and 4 wires - must admit I thought this didn't seem right. Don't suppose you know the part no. of the 2 wire stalk do you - would certainly help me out a lot? Dare say my clutch switch is fine then.
Stalk cost £41.78 inc VAT.

Omega General Help / Retrofit Cruise Control Problem on 2.5TD
« on: 09 October 2006, 21:16:26 »
Hoping someone can give me some advice.
I have read quite a bit about adding Cruise Control to Drive-by-Wire Omegas - I have a 99 2.5TD (last of old shape) which is Drive-by-Wire. It is my understanding that all is needed to install Cruse Control is the upgraded stalk (unlike on cable driven models). Then, when fitted, this may or may not worked straight away - if not a Tech2 will be needed to enable the cruise function on the ECU (although some will work without this as they are already enabled).
So..... today I purchased a brand new stalk from a Vauxhall dealers and proceeded to fit this (direct replacement) and found the extra cable that lays loose in the loom which also needs connecting. I then went for a drive and it did not work! So I went back to the dealers and managed to find a friendly vx technician who hooked up the Tech2 machine in an attempt to enable the cruise function. However, he was unable to find a menu allowing this to be carried out - apparently this should be under the 'new programming' section but did not appear. He then went through other menu's and was able to find a reference to cruise control and that with the ignition on it had a 4.7v feed, but nothing else.
I have several questions I need answering.
1. I was told by vx parts man that there are a few different cruise switches listed, but when cross referenced with my chassis no. the correct one was part no: 9181014 which I purchased and have installed. Is the diesel stalk different to petrol models? Could I have the wrong stalk?
2. When I installed the cruise stalk - I noticed that the extra 'cruise wires' from the stalk has 4 cables, however the multiblock on the car loom side only has 2 cables going into it. I'm quite sure this is the right one as the block connector fits perfectly together and I can't see any other loose connectors?
2. I was advised by the vx technician to check if the clutch switch was present which I have and can confirm it is present - how can I check if this is functioning correctly? Replacement is approx. £20 + VAT but I need to know if the one I have is functioning correctly first?
3. Does this procedure only work on face lifted Omegas - mine is the old shape but as it is the 2.5TD I know it is the Drive-by-Wire type and have been led to believe it will work on mine.
4. Does the Cruise function have a light that illuminates on the dash?
Sorry for all the questions but I would really appreciate some knowledgeable advice.

Big thank-you to Nixoro!! I tried again but applied more force as you suggested (absolutley bricking it that the key was going to snap!). Anyway the lock made a clicking noise and the door opened!
THANK YOU VERY MUCH FOR GOOD ADVICE!

Yep got the key but it won't open! I only have the one key so am scared of breaking it in the barrel I used a reasonable amount of force but can't get it to open. The lock button sort of moved a few mm but that's it.
Is there no other way?

Hope someone can suggest a way for me to get back in my Omega.
I have just disconnected the battery (a long story why and not relevant to this thread). I have then closed the bonnet, but STUPIDLY I had locked the doors with the remote before disconnecting the battery and now I can't open the drivers door - must have dealocked them without realising.
I can get into the boot but can't fold the seats from there so that's a non starter and the drivers door barrel ain't opening the door lock. I also can't get the bonnet open - any quick suggestions without casuing any damage?

Omega General Help / Throttle Position Sensor Query
« on: 27 January 2007, 14:19:21 »
Just a quick query - maybe someone will know the answer. I am having problems with a lumpy idle while slowly coasting along in my Omega (2.5TD) but NOT when stationary.
Anyway today I have gained access to a 'Snap-on Diagnostics Scanner - MT2500'. Firstly, no fault codes are logged and I can't see anything that jumps out as being obviously wrong except for one possible thing. The Throttle Position Sensor is measured in both a % and voltage. At idle this is reading as 13% and only goes up to a maximum of 87% with the accelerator pressed to the floor. Surely these figures should be 0% at idle (i.e. no throttle applied) and 100% with accelerator pedal pressed to the floor?
Does this indicate a faulty Throttle Position Sensor? Is this contained within the accelerator potentiometer fitted above the pedal?
