Apologies for posting an Astra query in Omega forum, but the audio system in my car is found far more in Omega than any other Vauxhall, so I am hoping to get some help here..

I've a 2001 Astra with Siemens NCDR1500 stereo.. The previous owner had a wrong version of Philips CDC3 changer installed (-TA suffix) which was not working at all, so I bought a brand new version of CDC3 (-TB suffix) which is the right one for my car and installed it in the glove box with the plug pre-wired for CD changer.

Although new CDC3 came with a code, the system never asked for it.

The issue is that the CD changer does not work through CDC button on the headunit at the moment. It starts working when:

* The headunit is switched OFF and 4- CD magazine is inserted into its slot in CD changer.

Then headunit switches ON automatically followed by display messages of "Check Disc 3, 2 etc" and then finally the display message "Check Disc 2".

Then the first song of CD1 starts playing and then in 5-10 seconds, I think the CD changer freezes, the song stops and then nothing at all..

The headunit still carries on as normal if you press other buttons for audio, NAV etc... The only way to re-start CD changer (for again 5 seconds only) is to switch headunit OFF, take 4-CD magazine out of CD changer and insert it back again when headunit is in OFF mode...

I have to take the sat nav disc out every time I wish to listen to an audio CD which is not very helpful at the moment..

Could someone please highlight what is going on?

Thanks for your help in advance....

Hi, Would just like to add that Vauxhall part number for my new CDC3 is 91157147.

I tried to insert pics but don't know how as the windows browser tab did not open on this thread..

[Marks DTM Calib]

From memory (the Omega does not support CDC3 units) the CDC3 is coded to the headunit using tech2.

[ksareen]

Thanks Mark

I've a DTC/ code reader that I bought off cheap from fleebay that has a blue tech2 sticker on it, do you think plugging that one into OBD will help?

Or
Do you recommend anyone with a tech 2 who can do this job? I hope you won't say Vauxhall as I don't know how much they would charge.. any idea?

[TheBoy]

I have same setup as you in my Omega (NCDR1500, CID, CDC3, and telematics unit), so its a system I know reasonably well.

The CDC3 is paired to the NCDR1500 in the same way the screen is.

Do you have the original code for the NCDR1500?

Where are you, might be worth updating your profile, as we have 4 tech2's in the club - see http://theboy.omegaowners.com for locations.

It is possible your replacement CDC3 has a knackered laser or mechanism.

I'm afraid a dealer will not be able to help you in this scenario, but there are options

TheBoy's mail has put a smile on my face, thank you so much as I've the same setup (with telemactics etc), so I've got some hope now..

I don't think my NCDR1500 came with any code, the reason is that I've disconnected it several times and changed battery etc, but it has never asked me for a code. It just works fine when I put it back even after a month. I will still take a look in the books but I very much doubt that I've a code for it.

The CDC3, on the other hand was bought "brand new in sealed box" from Vauxhall dealership who ran a clearance on fleebay (hence the part number 91157147), so it would be upsetting to find that the laser is knackered. It did come with a code but the headunit/ display never asked for it..

I could not find a way to update my profile any further but I shall look again. I am in Basildon, Essex and travel regularly to Birmingham on weekends..

Thanks once again TheBoy, I hope you would get me sorted...

[Dave DND]

Sounds to me like its the wrong version of CDC3 for the NCDXX units. The fact that it came with a code are the reason I have cause for concern, as the NCDXX units use a different version of CDC3 that is not coded.

[ksareen]

Dave

You may be right. However, please note that I've presumed the 4 digit number stamped (literally) on the box in which the CDC3 came as the code, you may laugh at me if that is not supposed to be the code as it never had any kind of label on it to help me understand what it meant..

Oh dear, now time to take the smile off your face 

The NCDR1500 does indeed have a code. Its not a traditional code in the sense of one that needs to be input after battery disconnection, but a pairing code.

The Infotainment devices - NCDR, display, CD Changer and Telematics - are all paired to each other at time of install.  The idea being that if one of the items is removed, it can't be used elsewhere, as it hasn't been depaired from its partners (its not as entirely clear-cut as that, but thats the principle).

To replace faulty components, assuming that the faulty component is too faulty to allow the other components to be depaired from it, you need to replace the faulty component with one in 'Delivery State' (ie, unpaired), and pair it to the other components using the original pairing code of the other components.

If this original pairing code is unknown, you have a big problem, as we have yet to devise a way to depair the NCDR1x00 or the telematics units.

Do you have the original CDC3 that was fitted to the car, or wasn't one fitted?

[TheBoy]

Sounds to me like its the wrong version of CDC3 for the NCDXX units. The fact that it came with a code are the reason I have cause for concern, as the NCDXX units use a different version of CDC3 that is not coded.

Thats less of an issue, as we can work around that.  I was using a 'TA' CDC3 with a NCDR1100 in my old diesel Omega.

[Dave DND]

If you are thinking swapping the vertical PCB with the original, that would work.

I`m thinking it sounds like a CDC3 from a CCR600 combination?

[ksareen]

Dave, TheBoy:
The CDC3 from CCR500/600 is the one with ident -TA which is what I had in the car before.
The car was never fitted with a CD changer from factory. The previous owner saw the plug in the glove box and put one CDC3 (91157146 or -TA ident, the one you use with CCR500). It never worked at all.
When I bought this car, I did some enquiry and found that I need a CDC3 91157147 (or ident -TB) to work on this car. So I sold the -TA and bought the -TB.
I made some progress as the music started playing for 5-10 seconds which means the wiring/ unit are OK but some configuration needs updating for it to continue to work OK.
TheBoy, I don't have the carpass/ vehicle pass card. Would the NCDR1500 code be on there? If you could mention an example, I can scan through the books (including the audio and NCDR1500 ones) and see if I can find this code?

If it was factory fit, it would be on the carpass. Replacement carpasses from dealer between £15 and £45 so shop around.

It is likely to be same as immobiliser pin, certainly thats the default on Omegas.

nah, the one he had was from ccr600, new one sounds right for ncdr.

Need original ncdr/screen pairing code for this, then a bit of dodgy tech2...

[ksareen]

TheBoy

This does seem to be factory fit as I've all the manuals etc for audio and telematics..

So, if I get a carpass, are we back in business?
I will tell them explicitly the reason for getting the carpass being the need of code for NCDR/ immobilizer as they are the same.

I think there won't be a need to depair the CDC3 as it was never fitted in a car before (bought it brand new)..

Does the car need to be present at the dealership to get a carpass? Any experience with £15 ones, could someone name them and fame them please?

P.S. TheBoy: lol @ dody tech2s...
