CCCU repair service

A2OC

Moderator
Hello everyone.

An unfortunate A2OC announcement. It would appear that due to the actions of member/s on this forum that the Central Convenience Control Unit (CCCU) repair service offered by A2freunde member 'Lau' may no longer be available to our community.

This is extremely unfortunate and disappointing given that the CCCU is prone to faults and causes irritating gremlins in the A2's electrics. The repair service from Lau costs less than £100 including a loan CCCU whilst yours is repaired, as opposed to a new part from Audi being upward of £700. :(

The background in brief:

Members are alleged to have not been communicating or responding to messages from Lau; claims have allegedly been made that the repaired unit isn't fixed correctly, and the 'loan' CCCU given on exchange while the members component is repaired has not been returned to Lau.

The latter aspect of this is most disappointing, as if accurate, this is tantamount to theft from a fellow A2 enthusiast. Not good.

Lau is a highly valued and respected A2 enthusiast, he is an electronics engineer by profession and ( to our knowledge) is the only person worldwide who can repair the faults which arise with the CCCU. He tests the repaired component in his own A2 prior to shipping the unit back to the customer.

As it is likely that the person/persons responsible for this situation were introduced to Lau through this forum, the A2OC admin team will do its level best to address and resolve this matter in order for this service to continue being available.

The alternative is damage to our reputation as the service would be confined to the German forum, and also more A2's are likely to be sold on or scrapped because of the cost of repairs being prohibitive to owners in future. :(

The proposed solution:

We will contact Lau in an endeavour to resolve this. Without prejudice, we will also contact the persons alleged to be involved in the matter which has given rise to this situation. There is always 2 sides to every story, and hopefully this is a simple misunderstanding.

If any A2OC member has been dealing with Lau and has outstanding communication or any dispute over a repair, please respond to him and also contact the A2OC team using the 'contact us' facility or email us direct: [email protected]

In order to preserve this service for the future, A2OC is prepared to act as intermediary for the service with Lau. This would entail the service being auditable on one of the club forums, and a refundable deposit being paid to the A2OC Paypal account before the service is permitted to take place between Lau and an A2OC member.

Let's hope we can sort this folks. It would be a tragedy for us to lose access to this service as a result of a misunderstanding or the acts or omissions of a couple of individuals. Your comments or feedback on this are welcome, including our proposed solution. Will this work?

And if this post is a little close to home for anyone - please contact us in confidence, we're sure it can be sorted out :D

Disappointing news :(.
In an effort to re-establish this forums' reputation with Lau, I, through A2 Cars Limited would be prepared to represent forum members requirements for replacement CCCU's and act as a conduit to Lau. All work could be carried out at our new workshop in Milton Keynes and would go a long way in creating a "standard". If beneficial, I am prepared to carry some items in stock to facilitate a faster turn-around time.

Just an idea.

Excellent propositions. I was unaware of this service, and hope it continues to be offered by Lau in future.
 
Sad news, as I've got a 2nd iffy CCCU that I would like to get repaired.
A loaner isn't an issue as my primary unit still works and is in the car.

Does anyone have any info on what actually fails on them, as I'm a bit handy with an iron so if it's dry joints, I can have a go myself?
 
As our A2s age we will become more reliant on fellow enthusiast to provide economic specialist services. It's sad that one such provider has been let down.

If the A2OC is prepared to act as intermediary for the service with Lau (and maybe in time others) that would be great. Being auditable, a refundable deposit, and a dispute resolution, even better.

Thank you to the committee for their action. Hopefully it will save the service with Lau.
 
Update: solution likely

Hi everyone.

Further discussion with Bret who is an admin on the German site would suggest this matter is resolving itself.

Also, to the potential benefit of A2OC members we have the opportunity to improve this service by making it available within the UK at a much reduced turnaround time.

Discussions are due to take place with Lau, (who remains the only known authority to physically repair faulty Cccu) and further details will be posted when the technicalities are agreed upon.

Meantime, this is good news for the club and provision of a cost effective solution to a common fault with our wee cars.

Thanks for your support.

Hi All,

If the offer to help with coordinating CCU repairs is taken up by Lau, it would be a huge help to A2 owners. It is likely that this, and other electrical issue, are likely to increase in frequency over the coming few years. Services such as this will ensure that repairs are, where possible, economically viable. I was shocked with the attitude of one Cambridge based dismantler when I objected to the £300 they quoted for the CCU, Audi do them for £327 new! It seems that as demand for used parts go up, the scrap value will see many good cars handed over to butchers for parts.

Oh BTW I just purchased a CCU for £65 from a fellow car enthusiast. Its been programmed now and I finally have working central looking and lights!

Hi All, I've just joined and ironically the first thing I've looked at relates to the problem I need help with!
Is there any further development with the situation with Lau?
I need to get my CCCU repaired which is an 8Z0 959 433 Q unit, if the Lau thing is resolved how or who do I contact?
Many thanks
Itchy
 
There is communication between Lau and forum members, please be patient a little longer.

Hi Itchy

Whats wrong with your module? My last post asking this was deleted by a moderator as I had broken a forum rule.

I have a CCM that I replaced since the key remote no longer opened the doors but was fine using the key. All other convenience functions operated fine. You can have this module if it is of any use?

Anyhow hopefuly moderators will go ok with the above.

A key that no longer operates the central locking often just needs pairing again, just putting it in the ignition, turning the ignition on and pressing the lock unlock buttons does the trick almost every time!

should have mentioned that I had the unit diagnosed using VCD and the remote chip has malfunctioned. That said everything else works ok.

Hi MAXAudi,

As I said, new to this. Not even sure I'm replying correctly!

I've no idea what's wrong with it specifically, only that every now and then the battery would be completely flat if the car had been left for a couple of days. After looking online it seemed the CCCU was the most likely culprit, so I removed it and the battery has been fine for the last 3 or 4 months! Hence I'm now looking to get mine repaired as they are too expensive to buy new! Any help or advise would be most appreciated.

Many thanks

Hi Itchy,

I am not an expert but if the module is causing a power drain I suspect a fault exist in one of its components. If this is the case, a fault code should be detected via VAG VCD (Audi diagnostic software).

I would advice that you have the issue diagnosed first before replacing the CCU unit. I would also avoid dealers since diagnostic prices soon skyrocket!

Having opened up the CCU I know that it has a number of relays and other chips controlling various interior conveniences. You could try re-installing the CCU and removing fuses one by one based on each convenience. If you eventually find that removing a specific fuse stops the drain, it is possible that the CCU is keeping this convenience switched on whilst parked. Another way of doing this more quickly is to use a multimeter that measures voltage across a circuit. You can buy them in Maplins for about £10 and various guides exist on you tube. The multimeter has two probes, a positive and negating, test each fuse one by one to check which ones stays on. Remember to do this after the car has been locked for about 5 minutes or when the speedometer has switched off. I am not sure how long the car stays on after being switched off so the above is a guess.

Depending on which convenience is kept alive, you could just run the car without it. For example, if it is the interiors lights, you might decide you can live without these if it avoids replacing the CCU module. If it is something more essential then it a repair or replacement will be needed.

I will PM recommendation for diagnostic work separately since forum rules are pretty strict on advertising.
 
A gentle warning. Please take care when using a multimeter to test wiring. Make sure you do not "test" any airbag or pretensioner circuits to prevent inadvertent activation and possible injury.

Hi Guys,

I did run some tests a few months ago and if I remember correctly(unfortunately I think the Alzheimer's is kicking in) it was a fault on the alarm controller. So I'm fairly sure the offending relay in the CCCU needs replacing, I just want to get it fixed as I can't stand the ear ache any more!

Is there anyone else other than this Lau character that can repair them?

Cheers

Mitch
 
Ah ok, well in that case my old module will resolve this but you will loose the ability to open the car using the remote. You will therefore need to unlock and start the car the old fashioned way. If you can wait I am sure Lau will be up an running soon.

As stated in the opening post of this thread, Lau is the only known person worldwide who can repair the CCCU.

The current status on this is that a member of the forum admin team has messaged Lau and an admin from a2freunde ; so we hope to have a positive outcome. This can take a bit of time when confined to written communications between people who really don't know each other; so please be patient.

Fortunately one of our team has fluent German so this should assist.

May we please request that any posting on this thread is confined to the subject matter of resolving the repair service from Lau and not drift towards any specific problems a member may be having with their car.

There are many threads on the diagnostics and servicing and repairs forums which discuss the CCCU. This is very much appreciated and will assure that this discussion is not diluted.
