No worries mate.  From what you say it certainly sounds like the crank sensor.  I would not drive it until you get the new one fitted as you have indicated in you last post.  You can be sure that it will let you down if you do.

Good luck with changing it - just follow the guide and you will be fine.

Hopefully back on the road again very soon!

Good luck with getting the correct part.  I have a trade card.  I don't know what kind of a hurry you are in but I could get it for you and post it it on if you like - this will add time before you can effect a repair though.

Anyway, let's hope that it is just the crank sensor and normal service will be resumed!

Car was registered 16/06/1998.....W0L0VBP69W1229357..hope that helps..if I know exact part can get next day delivery so up and running properly..although as stated before is running ok so could this all be "red herring" these sensors play up and then die or just die

Either failure mode is possible...     Mine played up with poor starting, showing a code 19, so I changed the sensor immediately on advice from here.  Result - starts as it should do and has done so ever since.  Others have experienced different forms of failure.

When you say poor starting what do you mean?  Did the engine turn over for a long while prior to starting for example?  I am interested to know as mine does not always start "on the button" as I feel it should.

Crank sensor is easy to see from under the car.  Get under the car and look up at where the oil filter is on the passenger side of the engine.  You will see a black right angled plug with wires coming out.  This is the crank sensor.  I think that it is held in position with a single bolt which is probably a torx.

If the sensor is failing, you were lucky to be able to start the car again - apparently, they normally die and it is a tow home.  Sort the crank sensor first and then reread the codes and see if the others that you mention appear.

There is an excellent how to guide on the crank sensor replacement by the way.

Hope this helps

Many Thanks for that, it makes sense. I doubt the last owner had it changed as he did nothing else to it.

Do you know when the cambelt and tensioners were changed (if at all)?  If not, or you are unsure, have them changed ASAP.

autobox fluid (would you believe the vauxhall dealer couldn't work out which one I was supposed to use?! - probably would believe that..)

 ;D ;D ;D ;D ;D ;D ;D

Have the pump changed anyway, no matter how it looks to them. Who knows what happens in 40k, with the engine stripped down that far, might as well do the water pump for the sake of 30 quid!

Agreed - get the pump done - total peace of mind then!

Omega General Help / Re: Performance Braking?????
« on: 26 April 2007, 22:39:08 »
Likewise, I no nothing much about performance parts - always preferred to keep my cars standard.  However, what I do know is that you should use vented discs and not solid.  The Omega has vented as standard in any case.

As The Boy says, the brakes are very good and I too suspect that there is something not right somewhere on your car.  Maybe a piston in the brake caliper has seized or the sliding section of the caliper is seized?

Good luck with whatever you do.

Well, I think I'll be going back to have a chat with the manager on Monday armed with a print out of the relevant page from their web site because there is a world of difference between what they promised and what they delivered.

I will be asking to see the before and after temperature measurements (I don't believe they bothered to take any) and asking for a refund if they can't produce them, especially as they claim to charge nothing if there's not a 10% difference between the two (thatever 10% means when dealing with temperatures - no doubt they work in degrees Kelvin!).

..but I am conscious that it's hardly swealtering weather at the moment, the car is new to me so I'm not familiar with a system that's working properly and maybe my expectations are not realistic. Maybe someone could confirm based on the following that my system is not working satisfactorily.

The outside air temperature was 15 degrees today, the sun was shining and I drove home (20 miles) in shirt sleeves with the climate set to "lo" and the fan at full speed. Based on other air con systems I have experienced this should have quickly lead to an uncomfortably cold car. The reality is that it was a degree or two colder than I would have preferred but I didn't really get the urge to give up and dial in some heat.

The air con does give some cooling. Switching to eco mode does raise the temperature by a few degrees at a guess. The compressor is engaging, the auxiliary fans are running at low speed and the condenser looks clean and not blocked with debris. The pipes in the driver's footwell to the heater matrix do run reasonably cool (slightly warm but not at engine temperature) so I think the HBV is cutting any significant supply to the heater matrix.

I wouldn't have minded if they'd said that there was a fault in the system that can't fix. They only offer a recharge service after all. I wouldn't really have minded paying for their efforts if they'd been up front with me and provided whatever suggestions and information they could as to what was wrong. In the event they sent me packing hoping I wouldn't argue.


Agreed - your system does not seem to be running a peak efficiency - like you, I would expect the car to be too cold.

Also agree with your other comments - good luck with the refund.

I expect the Kwik Fit people work at -273 degrees Kelvin - certainly in the brains department anyway!

Did you have to pay anything for that woeful service?

If the system is now fully charged, then some diagnosis is required - i.e. what pressure is the system running at on both the high and low side, is the condenser being cooled correctly, is the received / dryer in good order, the evaporator, the expansion valve and, finally, the compressor??

Good luck with getting it sorted - and at a low(ish) cost.

Hi Jon

Thanks for your replies - all very informative.  I will take a look at the link your provided.  I have an interest in A/C systems in cars and my first car with A/C cost me 1000 to repair (this was in 1999) this was on my Cavalier which I still have and the A/C still works as I have it re gassed and a new receiver / dryer every 2 years.  Has worked for me which I why I recommend the same to others.

How long should a system have a vacuum on it prior to a refill with gas and lube?  I was always under the impression that the longer the better but have since been advised that this is not the case.  Which is correct?

I also agree with you about the cans of gas available at Halfords etc.  I always advise people against using these for the reasons that you have stated.

But the receiver / dryer should be removing any moisture in the refrigerant.  If it is not, then it needs replacing - all this of course assumes that there is moisture in the refrigerant.  Could also be the expansion valve at fault.

As Kevin says.  By the fact that the compressor is engaging, I would suspect that there is gas in the system therefore fairly safe to say that there are no leaks.  As Kevin says, a decent outfit will check for leaks in any case.

It is vital that they do the service as already said above.  After it is done and the system is working again, make sure that you run the air con for a minimum of 10 minutes at least twice a month.  This keep the seals is the system nice a moist and prevents them drying out.
