Enabling Nav in Cluster Display

[miro]

Thinking more about this, I think that the dealer has screwed something up.

Your car is a facelifted W208 so you have all the right connections for the diagnostic plug in place. The odd thing that the dealer did was to somehow manage to 'lose' your cd changer from the COMAND. If I remember correctly the dealer doesnt actually need to touch your comand or its config, just enable NAVIGATION = PRESENT and save.

Try Tony Purslow in Guildford, they enabled mine and I have a CD changer like you.

I have not seen Pin 34 on any CLK I worked on. I moved it there myself in all cases.

Please go into diagnostic mode (select AUX input by pressing SYS key, then selecting AUX). Then hold down the 3 buttons, MUTE, 1, 3 all together until diagnostic mode is entered.
- Now goto the configuration screen, and tell us what is ticked and the numbers in the bottom left
- press RET and goto diagnosis then D2B components
- does the actual column match the config column
- please tell us what is shown on that screen
- press RET and go into error list, pls tell us what is there, then hold down MUTE and 0 together to clear the error list
- press RET twice and go into versions, wind down the screen to D2B and go in there and tell us what is there

Hello again gents, thanks for all the replies so far.

Just to see if it helps, here are the answers to the questions posed by Richard.

Answer to 1.
TV Tuner: Not ticked
Telephone: Ticked
Telematic: Not ticked
Telematic via D2B: Not ticked
Analogous BOSE: Not ticked
Combi Self Aligned: Ticked

Answer to 3.
The actual column matches the config column in some cases and not others.
POS ACTUAL CONFIG
000 1C8 1C8
000 190 0F0
OFF 000 190
OFF 000 000
OFF 000 000
OFF 000 000

Answer to 5.
The error list had the following on it.
SPE Code Type CNT State
N1112 0X0000 021 P
B1767 0X0001 002 A

I cleared these errors with the instructions above.

Answer to 6.
Ser No. SW Ver. D2B Proto
Handy No No No
T-Aid No No No
SBS No No No
CDC 00087178 1.12 2.3
Sound No No No



According to the Russian website where you can see the spec of your car from the chassis number, I've got BOSE, should that be reported somewhere above? Or is it somethat that needs to be enabled?

Also, I should point out that the dealer DID enable Nav in the cluster display, but in doing so that stopped the CD changer from working. I value the CD changer more than Navigational arrows so had them change it back.

So, does the collective wisdom say that I need to swap the diagnostic pin over to resolve all the problems? Or does this issue run deeper than that?

I really do appreciate all the assistence so far.

Cheers,

Andy

Answer to 1.

OK, as you have BOSE (and BOSE was analogue in the W208) Analogue BOSE needs configuring. I cant remember whether the W208 needs combi-self-aligned or not, i.e. if the cluster self-centres text that the comand sends it - it is obvious if it's wrong once the cluster is working

Answer to 3.

OK, 0F0 is the code for the phone - comand came out of a car with a phone in it. The COMAND see itself (1C8) and the CDC (190) - but it is programmed to think there is a phone in the loop before the CDC - that should be fixed - and may be the cause of the oddities. (It may not be though, only fixing it can tell!)

The error list had the following on it.
SPE Code Type CNT State
N1112 0X0000 021 P
B1767 0X0001 002 A

N1112/0 is a D2B error, and I suspecct that is caused by the misconfiguration above - BUT it could be caused by a problem on the D2B bus - which would also give you the "no cd player" problem.
B1767/1 means that the wheel size has not been properly set on the COMAND - you should do that in the menu where you set the tyre size and tell it if its old or new tyres.

- Check in a day or so to see what errors have occured.

Answer to 6.

Thanks!

You need to move the diagnostic pin [assuming you have the connector under the bonnet, which I think you do] and have the MB dealer reprogram the COMAND (enabling the Analogue bose since you have it), and reconfiguring the D2B ring, and then try the cluster setting again. The dealer should then check that the navigation instructions look OK on the centre (i.e appear correctly formatted), if not, they may have to turn off/on the "cluster with self centering text" option in the COMAND coding.

Richard I can't thank you enough for your help here. I don't know how or where you learnt all this stuff but the fact you do is a huge bonus!

If anyone has a picture of the diagnostic connector on a W208 facelift model I'd be most grateful. Also, anyone have experience of swapping these pins over?

 

[Rose Chap]

Things have gone from bad to worse.

Now the CD changer isn't being picked up at all. I think the problem must lie with the C1 connector as power isn't even getting to the changer (I can't eject the magazine), but no amount of wiggling of the connector is yielding any joy.

Does the C1 connector use the same pins as the C2 connector or does it need longer ones? I used the same pins as I used for the C2 connector and I'm wondering if they are long enough.

Am I on the right track with this or is there something else I should look at?

Should be the same pins, the connector shells are both made by AMP. Have you got a volt-meter ? Unplug the connector at the CD changer end and check for power there ..

Also, see what the fault codes say, and see if anything at all is visible in the "actual" column on that display of the things on the D2B fibre bus I mentioned before

Alrighty!

I nailed the problem down to the pins on the back of the COMAND not making contact with the pins in holes 5 and 6 of my C1 connector (which supply + and - power to the CD Changer) due them just not being pushed down far enough into the connector.

Being unable to push these pins any further into the C1 connector I needed a solution. I must have seen too many episodes of the A Team as the fix I arrived at was small lengths of tightly wound aluminium foil inserted into the C1 connector, with the proper pins pushed in on top of this.

When the C1 connector is connected into the COMAND, the corresponding COMAND pins compress the aluminium and ensure a tight fit and ergo a connection providing power to the CD changer!

:bannana:

I've checked a few things and my diagnostic connector is under the steering wheel (thanks S1GAR), so I shouldn't need to swap any pins on this according to what has been said here before.

Now I'm back in the position I was a week ago, I still need a friendly dealer with a STAR machine who can interrogate my system properly.

 

[s1gar]

i think you have not crimped the wire on properly (without sounding rude). if its not done properly the pins dont go all the way into the block. i had suffered with this. i bought the merc loom because i am rubbish a crimping wires the smaller the pin the worse and harder it is because they bend slightly and hence dont fit in the block. the onlywire i had to put into the block was the speed pulse wire. it would not go in excatly as you have described. i applied some prussure and it eventually went in. anyway hope this helps..................p.s. if it was a real a team job you would have made the foil from a coke can and flattened it to exactly the same thickness using a cucumber.....have fun

In praise of Greenoaks!

Another update to this tale of agony and ecstasy.

Yesterday I kompressored into Caversham with the intention of seeing a MB specialist to get my cluster re-coded to show navigation arrows and for the COMAND to be told that I don't have a phone but do have BOSE.

No luck, the MB specialist in question don't have a Star machine (despite what the lady on the phone told me on Friday), and the chap advised me to go to Mercedes.

Feeling somewhat deflated at this point, I decided to drive to Greenoaks in Reading to see what they said, not expecting great things, given their reputation on here, and the fact it was a Saturday morning.

To my surprise and delight, I was quickly introduced to the service manager who said "I'll just see how busy my guys are" and lo and behold came back to ask for my keys and took my car into the workshop there and then - all without an appointment.

They changed the cluster so now I have the arrows I was wanting which was excellent, but they did say that they couldn't interrogate COMAND as it wasn't hooked into the K Line diagnostic wire.

Given that this little buggering wire seems to be the bane of my life, I asked him to show me where the diagnostic interface is. Answer? Under the bonnet, the oppostite side to where the fuse box is, near the air con system. This is a breakthrough as this was getting confusing. Some facelift CLKs seem to have it under the steering wheel (s1gar) and indeed I seem to have a port there too, but maybe its not used?

Now I know what I need to do (pin swappage on this connector) there is only one final hurdle to jump before COMAND can be coded properly.

As soon as my hangover recedes enough to allow egress from bed I'll head outside and poke around. Pictures to follow!

One final thing to add, Greenoaks were really really good. Not only did they take me without an appointment, they did the job in about 10 minutes, and the bill? £0.00!

Well done Greenoaks Reading!

It is comforting to know that there was no exceptional cause and that the matter was resolved in the usual way. Would hate to think there was a gremlin.

You could probably have done this on the forecourt, it actually takes about 10 minutes if you have the tools ready

Quite agree Miro! Thankfully this problem was fixed with good old Waitrose aluminium foil!

 

[BarryS]

I'm sure I jinxed you with my earlier congrats (before the problems) so I'll say nothing until I hear everything is fully OK. Did want to add that Greenoaks Reading did a good and fair job for me on my first service although they failed to add the COMAND arrows into the speedo display but from your experiences I'll get them to have another go at the next service time.

Yup. Miro, have you seen any real gremlins from the D2B ordering ? I've heard of oddities in the voice-rec/phone when thats wrong.

Cheers

I use Greenoaks of Bracknell, and I find them superb. (Sales, Service and Parts).

Given Greenoaks did rather badly in the "MBClub awards" , is it one branch of Greenoaks that is causing bad feeling ??

Cheers,

Richard

There are several strict rules in MOST. The voice control must be before the UHI module and also I have found that if you have digital TV tuner and Harmon Kardon then you may get a random louder and softer in the volume - from complete silent to totally loud. Changing the order of the tv tuner and amp seems to remedy this.

As for D2B and critical faults cause by order .... havent really heard of it but I would say that the ring is sensitive to bad joins. I rewired my whole car with a fully optioned D2B optical ring from factory. I found that I have no problems at all.

I am just about to pull the whole thing out and go for MOST in my year2000 W203

I think the problem with Greenoaks seem to centre around the Slough branch, though they were fine at replacing a blown headlight bulb the other day - all done with no appointment for just over a fiver in the time it took to read the front page of the Telegraph.

Interesting to hear you really rate the Bracknell branch - I might give them a go next time I need a service.

 

[BarryS]

I've never found that I could book into Bracknell - their service advisers are always busy, receptionist takes my number but service never call back - this has happened 3 times before I gave up on them for good.
Their technical guru also couldn't tell me how to get the phone working when I bought the cradle from them. They wanted me to book the car in for STAR programing. I later worked out myself that I needed the radio to be turned on (weird I know), as simple as that. That was before I replaced with COMAND.
Finally, their courtesy car is a Smart. No thanks.
I'd definitely stick to the Reading branch!

Hi i am in Kent but i can always carry out programming with my Diagnostic equipment.

Staff actually rotate so be careful... Slough branch was enough to stop me going back to Greenoaks for life (apart from a blown bulb) that I had to source and fitted it myself.
