I use watchmakers eyeglasses, 2X, 5X and 10X. It may have been better to just "touch-up" the black areas, leaving the white symbol alone?

David. that's what I did (or try to do) but occasionally got some on the clear [white as you put it] and then scraped off but that scratch. Next time I will try using a sharpened match say - i.e. something a bit softer. Better still, a smaller brush, steadier hand and more patience!

........[fuel flap switch].........
I think they are about £18 new but I wanted to try this as I might now tackle 2 of my other switches that are worn - air recycle and scan - the latter will be a challenge.

No luck reassembling the fuel flap switch today, just couldn't get the button to stay in the housing, so bought a new one. My local independent Audi garage [Audi VW Centre in Melksham] got one within an hour. It was just over £21 (falling £ doesn't help) compared to £30 to £36 on fleabay. Mine is a genuine VW Group item (according to the other side of the box).

They said their distributor had 2 on the shelf - now only 1 so don't all rush at once!
 
. . had a right result. Two amber lights on the dash, cruise control not working and brake lights failed. Took it Coventry Audi who, while I waited, fixed the lot (repaired the brake light switch as none in stock and on backorder). They also fitted the heated door mirrors that recently arrived from the group buy with Crewe Audi and then washed and vacuumed the car.

And the best bit? No charge. As I said, a right result.
 
Well, a really big moment for us at the weekend.

We said good-bye to our A2 after 12 very happy years. We bought it as the second owners at 4 years old and apart from pepperpots and replacement seats, it was pretty much as it was the day it left the factory having accumulated 90k miles in 16 years. Very sad to see it driven away - it's been nothing short of spectacularly good.

We've just bought our second brand new car in 25 years (I don't include company cars which were borrowed and possibly not cherished :rolleyes:) and as its Japanese, we're hoping for 10 good years. It's a hybrid so hopefully it won't drop out of fashion quite as quickly as a diesel would have done.....

The even better news is........the A2 is staying in the family. :D Our niece in Sheffield is just about to qualify as a nurse so this was a gift to her to help her get to and from work. So if you see an Azure Blue 51 plate A2 with pepperpots and and Essex registration 'oop North, that'll be her!
 
TODAY I...........

The A2 has been having a battery drain problem but now its hopefull been traced to the CCU unit .

My local mechanic has found that removing the right hand plug in the unit to stop the current drain..

The plug has been disconected over the weekend and all seems ok ..!

The car is reading above 14v now when running ....

But what now ? Can this be traced further and the correct part replaced..

Any help greatly appreciated

Stevie

It would be worth trying a replacement CCCU.

I could lend you one to try out if that would help.

Hi Stevie,

The right hand connector is the main power connector for the CCCU.

I don't think the diagnostics have actually given too much of a clue as to what is wrong.
Just because the power has been removed from the CCCU and no further current drain is noticed, doesn't pinpoint the issue to the CCCU (unfortunately).
The issues could still be any part of the Comfort System.

Trying a replacement CCCU might also not be respresentative of acurate diagnostics.
The swapped CCCU would need to be coded to EXACTLY the same coding as your existing Q-code CCCU, otherwise systems that are not coded will not partake in the Comfort System, and once fully coded you might still have a problem.

There are many things that could be causing a drain, and a good way to start troubleshooting is to remove all fuses from the fuse box and test current draw using a digital multimeter.
Replace each fuse, with all the cars doors closed and test each one 5 minutes after inserting and without opening any doors or turning andthing electrical on or off.

It can be a difficult task fault finding these issues, but if battery drain is occuring overnight, or even over a couple on nights, it's likely to be something quite substantial (depending how good and how new your battery is).

Rob from WOM Automotive diagnosed a very hard to identify issue some while ago now that was a failed front door window regulator/door control unit - basically the electroic module that opens the front front window and determines what the door locks do.
If you have a search for WOM or battery drain, I'm sure you'll come across the thread.

Good luck in resolving - and have patience.

Hi Steve.

sounds good.:)

would this just be a case of disconnecting the battery , remove the plugs and swapping the unit over ...
if this helps the issue then i know its an CCU unit problem.??? the central locking was making strange sounds before the plug was removed . so maybe an issue there...

Are you talking about a new unit or a used one. Also is there any aditional work needed when carrying out this swap..

Hi Jeff..

thanks for your reply..

i purchased a new Varta battery thinking the old one was the issue ,but its still draining over 3-4 days ...

i will pass on the information to the garage and hopefully something will show up ....

Contra to general opinion, I have swapped at least 20 CCCUs andn not one has had to have any coding, be it rear electric windows etc etc.

The whole point here is to just try the swap as is and see if the issues remain, if they do still remain you have lost the 10 minutes that it takes to swap them over, it it eliminates it then fantastic.

As Jeff has said by unplugging the main feed you are not just disconnecting the CCCU, you are also removing power from the interior lights, alarm and windows.

So it may well NOT be the CCCU, but no harm in eliminating it as a cause?

You just unplug yours and plug in the replacement one/, the key fobs would need to be recoded to the CCCU but as this is just to see if this reduces the drain there is no need to bother coding the fobs.

The Q CCCU is the least reliable of the lot and you would be better off with an AF anyway.

If the one I lend you works you could swap the fobs for ones that suit an AF CCCU if you want to keep the better CCCU. (I could even code a new shape key for it if you have resolved your drain issue.

But for now a quick swap over MIGHT eliminate the CCCU as the cause at the very least.

I think my point has been missed - but I agree the CCCU swap is quick to achieve.

Hi Jeff,

your point was not missed you have a lot of experience and knowledge and your input is always on the ball.

I was just trying to explain about the swap.

All packaged up and will be posted first class tomorrow.

I have included a remote half that matches the AF CCCU (one that was actually paired to the CCCU I am sending).

So if it should fix the problem it may be worth buying it off me? (£50 for an AF unit is a very fair price?)

...collected my replacement A2 1.4 SE
91,000 miles, Island Green, soul black interior.
It came with every invoice for every penny ever spent on it, including the original purchase invoice.
It needs a couple of small jobs doing, new thermostat, new rear brakes (drums and shoes), the tracking is a bit out too but that’s being done tomorrow. Hopefully I’ll manage to get the thermostat and brakes done before weekend too.
I’ll post some photos tomorrow as it was too dark to get any today.

So glad to get rid of that awful BMW courtesy car and get back in a proper car.
