Mercedes s Class Command not switching ON

[Oktawian]

Hi there , I really need help as my command screen in my Mercedes s class 2007 doesn't turn on . The screen is black and I need it to work.

Is it some fuse or something? If so please tell me which one and where the fuse is

 

[John Laidlaw]

Think you need to take this car back - too many issues!

 

[Wighty]

Was it working before the dpf clean was done ?

 

[AMGeed]

I agree with John above.

Loss of power and a Comand that doesn't work suggest the car possibly has a few more hidden faults. If you can, get a refund.

you want me to travel back with a car that has no acceleration 1700 km again?

the car has no acceleration and i cant go back 1700km just to get refund. if i get the car fixed ill go straight up back to my country and tell them they made my car worst

 

[AMGeed]

Where is your location Octaiwan? Not Taiwan?

Obviously 1700km is too far to get either a refund or have it fixed by whoever sold it you.

Now you need to find an MB specialist, not main dealer, to locate and fix the cause of your problems.

 

[John Laidlaw]

He's near Luton now Roger and the car has come with him from another country- 1700km away and not practical to return. I'm suggesting a visit to Wayne Gates in Harrow- closer than 1700km!

 

[AMGeed]

Yes so I see now

Thank heavens its not Taiwan

Re the Comand problem, have a look at this guide to do a reset of the system. You should have a fuse chart either under the rear seat or in the tool kit or wheel well to check to see if any have blown.

yeah man THAT'S THE PROLEM I DONT HAVE ALL MY FUSES IN THE CAR LIKE A BRAND NEW ONE. i do have fuses blown but listen the mechanic tld me he was gonna take off one fuse and then put on back but he didnt and now i dont know which

 

[John Laidlaw]

What an absolute nightmare!
Can only suggest again the above, contact Terry at Wayne Gates or as Craig says Phil at Welwyn Merx, it might cost a little now, but you've a pretty unusable car at the moment!

 

[Oktawian]

some mechanic in my city did the command monitor in seconds now he has to do the acceleration as he said its might be the flaps in engine

 

[Oktawian]

he checked on the computer all the diagnostics and the flaps came up . I will ask him for the full problem list to be printed for me and everything that he has done and stuff .

 

[John Laidlaw]

Good luck

Its a diesel ? sounds like swirl flaps. These play up. They are little flaps in the inlet manifold that helps create turbulence as the air enters the combustion chamber... many think they are a total waste of space on BMWs and you can't even feel the change when you throw then away.

On the V6 Merc tractor engine, under the turbo (in the middle of cylinders between the V at the windscreen end) is the turbo. Oil mist / filth from the engine drips from the turbo and upsets the drive motor for the swirl flaps. Making it as good as new is quite pricey. Not sure how much or what the impact is on a Merc of binning them... but I doubt you need them.

If lots of fuses are missing that can be std in many modern cars. The slots for all the optional toys exist, but were never part of your car. Fuses for kit that should be there and should work on modern stuff I can image may confuse diagnostic systems from helping you fix stuff you do need or want to get working.

If the car is old check both batteries are in good condition (there's a huge battery hiding in the boot) or electrical gremlins will keep popping up

YEAH MAN, youre exactlyyyy right wow how'd you know. NICE. so the mechanic is telling me that its the turbo oil driping onto the engine everywhere but the thing is that it drips on the swirl flaps and he wants a lot of money for the swirl flaps power actuator or something like that . the thing that powers the flaps i think.

BUT HELP PLEASE AS I DONT KNOW HOW MUCH SOMETHING LIKE THIS COSTS. AS HE WANTS £385 for the power actuator i think for the swirl flaps. I went today morning and he takes £40 for the computer diagnosis check and so he told me what the computer said that the problem might be and so he caled me in and told me he would have to change the power actuator of the swirl flap? i think

 

[Mr Filipov]

Had he swirl flap actuator done on my previous CLS320 CDI last year. Standard stuff. Change the rubber seal on the inlet pipe with the MAFs that connects to the turbo every two years (about a £15 part from MB) and that should prevent that in the future. Keep in mind rubber perishes over time.

I'd heard 900 quid to do the whole job, that might be main stealer pricing, but I wouldn't bother chuck the swirl flaps in a skip where they belong

this is not your car but I expect this guy will know if you can bin them and for how much

there's lots of actuators on eBay for under 100 quid and you can probably get your repaired


just been reading 4.7k ohm resistor on the wires makes the car think the swirl flap motor is happy, then just jam them fully open and carry on driving as if you just spend 900 pounds - you can't tell the difference

You are purchasing a repair for fault code P2015 or other swirl flap related fault codes on all cars that use the Mercedes OM642 3.0 V6 Diesel engine. This is a common fault on these cars and is caused by oil dripping onto the motor that opperates the swirl flaps in the engine causing the motor to fail and put the car into limp mode. No power and will only rev to 3000rpm. The replacement of the motor involves removal of the fuel rail, injectors, fuel filter, turbo charger etc and aproximately 6hrs labour plus cost of motor. This repair emulates the swirl flap motor and prevents the car going into limp mode restoring power. After carrying out this repair your car will be completely back to normal or possibly better. There are no negative side effects, loss in performance or economy caused by using this repair instead of changing the motor so could also be used as a preventative measure. I run this on my own car so have fully tested it under all driving conditions including towing etc. This is an easy, permanent plug and play diy repair that requires only very basic tools, on most cars only a screwdriver. No mechanical knowledge, cutting of wires or soldering etc required. The repair takes between 5 and 20 min to carry out depending on car/ skill level and could easily be done at the side of the road so even handy just to buy and keep in the car to save being stranded as this problem usually just occurs with no prior warning. Comes as a complete kit with all parts required to complete repair and detailed fitting instructions
