So lets start from the beginning..

Biggest problem is, that my Elite is very jumpy when cold (cold?).. It jums doesnt matter at what speed, its like driving on a small wodden sticks / flat tyre etc.. Must admit, that there is small hole in backbox (its not loud). But must admit, that have got that problem not really when car is cold.. After 15 mins drive engine have got temp around 95'C, which I believe is normal. But car is still jumpy. Doesnt matter are you driving with constant speed or accelerating. Its OK only on neutral, but you can feel it as well, and again as well when stop. There is loose of power as well. Revs seems to be OK (not jumpy). No EML on, no errors at all.
After 40 miles last night and about 45 mins everything was OK (read: great as should be!). And again. Car cooled down, and this morning again the same..
That is first problem, a and Im hoping you will help me here!

Second problem - aircon (Dual Climate) - it blows only hot, doesnt matter is it switched on or off. Its winter, so Im not really bothered, but..   Prefer to know.. Been advised, that it needs only re-gassing...

And last questionsmall problem with my stereo, but please check ICE section.

Thanks in advance for all your help Guys (and Gals)!  

Merry Christmas and Happy New Year from all my family to all OOF Members and all their families!!  :exclamation

Replace the cold start switch mate, sounds to me like the engine doesent know it's own temp ?

Or cud be a vac hose split causeing a air leak...

As for the climate control, try holding the off and auto button at the same time for 5 seconds, that resets it, might be a long shot but cud be worth a pop...

Thanks, just one more quickie - have got small crack (2in) in right top corner -

http://www.motuk.co.uk/manual_830.htm

Will it affect MoT in the future?

Re aircon - should I do it on ignition on or off?

Re engine - where is that switch? Noticed (never seen it uin my previous Omegas (but temp seems to read OK) that after I will start my engine gauge is going down from top (red) to the current temp instead from bottom line (cold).. Which hoses should I check? If it is splitted hose, why it seems to be OK when car is (more than..) warmed up?

[ELITE-3.0-V6]

Do air con with ignition switched on..

The temp switch is not the same one that does ur guage, its for the engine management system to tell ecu of temp...

Its located beneath the inlet system and joins the 2 cylinder banks together i think its got 3 switches in it in total but not exact sure which one is which..

[Paul]

As unfortunately Im not mechanicaly minded.. How to get access to that switch? Is it DIY  job?

[Paul]

Ho ho ho, just one more xmas question!

My Cruise is not working - nothing happend after I will press any of these buttons. Any ideas? Or am I doing something wrong?  

[JamesV6CDX]

I think he is referring to the CTS - coolant temp sensor. This is located on the coolant bridge, at the back of the engine, in the V.

Before replacing or condemning any components, you need to diagnose the fault with a bit more clarity and direction.

The first step is to read if there are any fault codes stored in your ECU.

You can do this with a paperclip on most models and count the flashes - see maintenance guides "paperclip test".

Also, pull out a plug lead on each side of the engine, and check for oil in the plug well that may have damaged the plug leads. This is caused by leaking cam cover gaskets, and is common. This could well cause a misfire, and going by your description of the car being "juddery" this could tie in..

Go and check those things out, and also a visual check in the engine bay that all vacc hoses etc are seated and all electrical connections appear secure.

When you have done that, post up the results and we will take things further...

I'd second exactly what James said.

Read the fault codes then look for oil in the plug wells.

[Paul]

As explained before, no em faults in ecu at all. Will check plugs later as weather is terrible (rain instead of snow)

[JamesV6CDX]

As explained before, no em faults in ecu at all.

Have you actually flashed out the codes? It can still store codes even if the EML is not on.

If the issue is a misfire is on the HT side, then on a drive by cable engine such as yours it will not flag a fault code.

Let us know what you find in the plug wells. But personally I think the coolant temp sensor is barking up the wrong tree. Even if there was no / bad signal from the CTS, the engine can still run without a misfire, in closed loop mode.

[Paul]

Right, checked codes - have got 12, 144 and 145. I reckon it is not OK?

Short video:



And this is how car runs on cold (please note that on 2nd gear and 3rd Ive got my feet on the ground..



Didnt managed to check spark plugs - how to get there?

Checked for any leaks (air / oil) and cant see any at all.

One and only 'oily' place is on a last pic. Oil is clean, no water in oil and no oil in water. No maya as well.







Mileage is 120k

[Paul]

Anyone?  :-?  

[JamesV6CDX]

You don't need to take plugs out (yet) - just pull a lead off each bank, and look for oil in the wells...

[JamesV6CDX]

Codes 144/145 are immobilisor related, and unlikely to be a cause for concern.
Code 12 is the start of diagnosis - no cause for concern at all

So there are no tell tale codes

The "shaking" of the engine you describe does sound like a misfire, I'm prepared to bet it's DIS, leads, or plugs.

The first thing to try is to remove a lead from each bank (not a plug yet, just a lead) and look for oil IN the plug wells.

[Paul]

Thanks, but where are they located in X30XE? Can anyone point me in right direction?
