Omega General Help / Rear Springs (with self-levelling)

« on: 27 January 2015, 18:24:12 »

Hello,

Sadly, I cannot find any aftermarket rear springs to fit my Omega Elite saloon.

The dealership wants £292 for a pair!

Every Trade supplier has informed me that they can no longer get aftermarket stock. The only option is the main dealer.

The BOGE part number is 25.E49.0 - No longer manufactured.

The aftermarket springs I have had before with reference CS23067 - No longer manufactured.

This is very serious as my omega is now becoming so expensive to maintain that I simply cannot afford to pay such ridiculous dealership prices!

The Dealership quoted me the GM part number: 9193197 .

Any help would be greatly appreciated.

Cheers

Andy

Found a not too dis-similar saga on here and the problem was the rubber 0-rings sealing the breather box on the top of the engine. Two small o-rings.

http://www.omegaowners.com/forum/index.php?topic=54962.60

So I am going to have to go through all the breather system to ensure everything is spot-on.

The car will now only idle (very, very badly) for a few seconds before stalling.

My previous post which suggested it was fine when cold - but not when hot - has been proven wrong.

If I find the answer - and I prey that I do -  I will post it.

Have let the car cool right down and it is worse than ever!

The car starts and then dies after a few seconds.

Full throttle will not save it.

I will not be able to change Crankshaft Sensor with not being able to get it on the ramps.

Paperclip Test reveals Fault Code 19 & 13. 13 being O2 sensor - but the car has just had new down pipes and new NGK Lamba Sensors in the last month!

This car is costing me a fortune. I will have to hire a car now too!

The Bosch Crankshaft Sensor is Part No. 90540743 form the dealership.

I have been trying to narrow down things to the following:

1. The car always starts without any problem.
2. When cold the car idles fine - the ICV is recent and has been tested with another I have.
3. Car warms up and runs fine. No idle problems.
4. Once up to temperature I stop the car and re-start. No problem with idle. Fine many times.
5. Drive car over a longer distance and then stop for short while - 10 mins.
6. Car starts but idle is terrible. Car wants to stall.
7. No power to throttle. Foot hard to floor. Nothing - then suddenly kicks in. Struggles hold revs.
8. Full throttle application - which is difficult -appears to clear it.
9. Engine then runs and idles fine.
10. Turn engine off. Leave for a short while. Starts fine - Terrible idle as per 6 above.
11. Engine allowed to cool completely. Starts and idles fine.

Are these the symptoms of a crankshaft sensor?

I was not convinced that the Independent Garage that undertook the live data was fully competent.

Are we back to looking at the temperature sensor? The garage stated not.

Do I buy another ICV? This is getting expensive!

Help!!!!

Vauxhall Dealership has said they will test the Crankshaft sensor at my expense of £98+vat. If the part is faulty - they will fit another at no cost. If they believe that it could be some other factor - they will charge me the £98+VAT.

Again - the car always starts. It becomes lumpy and difficult to idle. Then stalls. There is never any problem starting the car.

I doubt very much that the sensor is the issue.

Does unplugging the multi-pin from the ECU cause any problems? Erase anything? Obviously, I would not do so with the ignition on.

Thanks for all your kind efforts so far - each is greatly appreciated - thank you

Following a live diagnosis with Tech2, the garage has informed me that both my MAF's are working (old and new) and that the temperature sensor is also working.

The garage suggested it could be a blocked or poor spray pattern by a fuel injector at idle but could not suggest any other fault.

They erased all the fault codes and when I got home I carried out the 'paperclip test'. It showed only one fault - 19 Crank Shaft Sensor. (one of the codes erased by the garage was 31)

This was replaced only the other week with a Bosch part bought from the Vauxhall dealership.

If it was the Crank Shaft Sensor I would have thought the car would not start?

Again, the car always starts. It only develops difficulty idling and this results in no power when you apply the throttle. Leading to the car stalling.

At a complete loss!

I have found an Independent garage with Tech2. Hopefully, he will be able to tell me if my MAF is working - but can Tech2 tell me if the engine temp sensor is at fault?

If the car does manage to resist stalling and gets me to the garage it will no doubt be hot. Will this have any impact on Tech2's ability to evaluate the engine temp sensor?

As always, I am at the mercy of the individual operating the Tech2. The telephone call was not reassuring so I have to be armed with as much knowledge as I can when I go in.

Cheers

Many thanks

I am going to try to find someone tomorrow who can provide live data as to whether my MAF is working or not.

Wish me luck!

Is this the one that needs replacing? The one with the orange circle around it?

So it is the Engine Temperature Sensor that may need replacing - not the Engine Coolant Sensor as per the kind 'How To' guide below:-

Thanks for the help so far

The fuel filter was changes only two months back for a Bosch Filter.

The problem occurs upon starting. Today I managed to get the car to keep going and when the engine temp was hot it ran fine. Took it for a drive - fine. Stopped and re-started a number of times - fine. Then I left the car to cool down a little - re-start - problem is there again. Bad idle and no power at all to the accelerator. It will then stall. Sometimes it will manage to stay alive long enough for me to manage to floor the throttle and keep it going. Usually, throttle makes no difference. Again - it's as if the choke has not been pulled out

I do not have a garage and to remove the top of the engine to replace a temp sensor is not a small job in this weather.

I have swapped the old Bosch MAF with the new and no difference. Except for my wallet!

Trying to find a garage who can undertake live data checks. Halfords Autocentre perhaps?

Please keep the help coming

The previous Bosch unit I suspected was faulty did not give any fault codes. There was no EML either.

Disconnecting and re-connecting the new one has left 73 & 74 in the car's memory me thinks?

I could not find a Bosch MAF cheaper - so I really don't want to p**s off the supplier as everyone else wanted considerably more. Cheapest was 175+VAT !

I did try a Cambier from a different supplier but that saw the car stalling upon acceleration and reduced the car's acceleration considerably.

I might check what its giving out by sticking pins in the connector's wiring when its running (trying to run) for both units against a volt meter.

The same part at Vauxhall was - wait for it - £265 + VAT !!! And it is exactly the same Bosch part!

It would be incredible if the new MAF was to blame?

Help!!!

The pins in the connector are fine.

The part was purchased at a reputable Trade Supplier. It is not a fake part off the internet.

It cost £185 !!
