Carsdoft 7.4 mercedes

Hello all,

I wanted to know your opinion on the carsoft 7.4 mercedes.

I took a multiplex 7.4 to troubleshoot and monitor a problem of consumption of my sportcoupe w203 2003.

convinced of his ability to see the data from the engine control unit (edc16) I had the unpleasant evidence that does not connect with the ecu.

All I see is good almost all the others... including that of the exchange drive that I would never have told you to read...

According to you there is no way to do it ? maybe by moving the pin assignment of the connector ??? I doubt that it is only a matter of multiplexing wrong since version 7.4 should read all of the machines up to 2004...


according to you, I hope to do something????


Thanks to all

azz how many answers !!! DOHHH

hello strange that you do not link should go well from 1996 - 2004

with autocom then see a whole of things, with das all....

thanks for the reply :)
in fact, I picked it up because I was hoping to see something about gl injectors.. but do not connect with any of the units!!
with regard to autocom... I also have one.. it's so good. But nothing about what I needed!
After that I changed the swirl I have serious problems of consumption.. before redo the ecu I wanted to understand what happens under the 2000 rpm where it seems to be too fat..

hello house, we have the w203 sedan but edc15, the injectors do not see them with autocom. I have problems on the ezs are tt deactivated keys

s?iega the problems that you have

the problem is simple !!! removed the swirl and the egr... all perfect. but the loss of performance and fuel consumption is high. Especially under the regime full of the turbine, where the well-known smoke and a drop in performance. I believe that you disable the swirl mechanically and not by the map has helped.. but before acting on the rail pressure and the torque limiters I wanted to be sure not to have any injector out-of-phase. Hard to say... and go in a mercedes would do little seen, which do not provide for this type of changes, and their quote for the repair was around 1800 euro.... unthinkable !!

the ecu is a edc16. and the medium has the nag5... then before each change I wanted to study at the bottom of the pattern and figure out how to change every particular, without going to trial... the thing that I hate to do a priori, without a minimum of theoretical certainties!!!!

unfortunately, I have asked several times to the opinion of someone who has more experience... but no one wanted to ever share your opinion ! so look.. in the meantime I have made over 10000 km, and everything is stable. Even I noticed that it consumes less taking the engine above 2000 rpm. And the computer board obviously takes the butterflies.. even indicates consumption of close to 20 per litre when I don't I get even with the wind at your back above the 13.... an exaggeration !!! at the best of times, I was always next to the 16..

hello then the swirl and the egr you should first close them from the map before making them mechanically, it takes you to an imbalance.( I speak from what I understand from the forum). before the consumption went well and the response?
excuse in the 1800's, preventive interventions had to do on the machine? with autocom you can not see the values of the mass air flow sensor, rail pressure etc.***** and it involves the exchange 5 nag
that errors have the ecu ?how many miles has the car? as the gear oil nag5?

the egr is already closed by the map ... the swirl unfortunately, no. I had some problems with the damos and insecurity do not have them removed. In the 1800 euros changed manifolds, motor mounts, ecu auxiliary heating and glow plugs. All things that I have already fixed ... the medium has 300000km... for what I don't dare to make changes without being sure. But it is perfect and does not consume oil for nothing. the transmission was rebuilt 100000 km ago... so all is well . the values I see all of them with autocom... but difficult to interpret if you don't have of the absolute values of reference as may be with the star.. a short lighthouse' accurate control of the mass air flow sensor to see if it falls into the standard or at least with loscilloscopio ec the face to get to the maximum voltage. for the rest I have no other ideas.. everything seems fine.

hello that errors from the engine and transmission(enter autocom in the exchange?) ? the swirl you should remove them from the map to eliminate the loss of power (according to me), I can't help you I've never done it.
the exchange should have need of a change of a dry ( every 60000 km), if you have any error can be or that should be replaced on a socket.
cos? not ? simple without knowing a minimum of things, if you can by a p? values.

no error motor exchange. Maintenance and washes exchange facts with regularity... but nothing do with my problem. .

Hello corland,

I have a W203 2.7 CDI 2001 and are 272.000 Km....
I too have the same problem with the multiplex car soft 7.4 reading to me from all the units, except that of the motor....

With regard to the increase of the consumption ? perfectly normal if you've changed the swirl removing it out of the way, as the cos? doing, you have changed the torque curve deteriorandola strongly at low revs..... As far as I know the problems of the collectors of these machines, when you reach Kilometraggi high, they can not solve, as many do, by removing the swirl, worth a strong decrease in performance at low revs and a strong increase in consumption.....

I do not think then that map to close them may be a better solution, why?, in that case, you'd have a significant loss of power at high engine speeds.....

What? the problem that you dannno the swirl? Oil is leaking or what?

However, keep in mind that today, you can find collectors new competition around 250 euro, with the replacement of the actuator pierburg you're around 370-400 euro of materials, if you have the patience to let you work on your own ? spending more? that honest and the machine returns new....

I know how much the material, but I discarded the idea, just for that reason. More forward collaudero' a system that I built to restrict the air at low engine speeds and we'll see what happens...

Surely any intervention, to be effective must act just on the conduits, in this case, it's not just the electronics to achieve an optimal result....

To read the CDI unit, instead of how you fixed it? I am interested as before to spend money on the things I would like to have confirmation from someone who has already? resolved....

use other types of diagnosis. but sessuna makes me see the autocorrezioni on the injectors

The car soft ? the only one in that price range that, if it worked, you should be able....

Can I know what do you think is the pi? suitable for w203, (except for the star, of course, that it costs too much)?

To tell you the truth, I think they must be all in the same way those of normal use.... those who more or less. Of course, to see something more than you have to have the star...otherwise it's just a simple diagnosis superficial!!!

But if you, having the same problem, you are already? managed to read the CDI unit, e.g. with the autocom, I can spend the money with a little bit of security in ir?. For this I would like to know which do you think is the pi? suitable for work with these models of the early W203.

but your problem which is???? and that means it is exactly ?

W203 C270CDI 2001. As a gi? mentioned in this discussion, I purchased a multiplex carsoft 7.4 which I read almost all the units except the engine ? the pi? important... If not I understand also hurt you ? happened to pi? or less the same thing with the Car Soft?

Are 273K Km; how problems should I change myself the collectors, why? oil is leaking from the hinges of the swirl, and I have a little bit of engine oil consumption that I can not understand what subordinates?by; the turbine is now worn out, games excessive thermal, seals or gaskets, just, efficient etc

I would like to purchase a diagnosis to be able to read the engine control unit as it should....

now I understand better... I also tried with the carsoft to analyse the consumption of the injectors, but nothing to do./// can not connect to the cdi unit. At the moment I use autocom and I have to say that it is definitely valid.... of course you can do all of that... including the injectors... but in compensation, it is also useful because ranges a lot.
For the collectors do not wait any longer .. edit and.. also because in mercedes you would ask for more than 1000 euros for the replacement... and then we add another 4 or 500 euro of ancillary things that are always to be replaced... and unfortunately with the means so that they are not worth very much and it's hard to spend so much money

Thanks for the straight; then, if I understand, autocom at least reads the CDI unit and for me not to ? little.

As far as the manifolds, I plan to replace them, but I have not yet proceeded because? I had other expenses (I just replaced the precatalizzatore top, eliminating the central, and the front brake discs. However I think I organizzer? to do the job on my own (Mercedes-within only if they are forced). The change does not convince me because, the afterlife? any mappings, all those who have done that type of work, have had problems with the delivery and consumption... I have to say the truth, you can feel that the collectors are not the best, but the car all in all is quite good (from the point of view of performance has only of irregularity? in the provision of power, I think due to the swirl that do not open more? smoothly will probably be deformed); the problem more? obvious ? leaking oil from the hinges that now have seats worn.... However, I also bought a programmer MPPSv13 to copy the map ori, but couldn't even with this a "Read" the control unit (me recognized, but not the law).

Strange,,, you should read it with tranquility! I read and I write to you even with the galletto 1260 ( even if there is courage to do so )...
For the cdi, please keep in mind that if you don't want to do anything that you want to only read the errors the elm connects perfectly !!! I use it with the cel to see the values of the rail and the other sensors when I do the changes... For the rest, Good Luck :)

Thanks...

Actually according to some, the cock not ? exactly the best... But if it works for you, that's okay, cos?....

I had assured that I would read without problems the map, but instead.... I don't know if something wrong in the procedure (I'm quite newbie in these newfangled electronics) I just hope that it is not the ecu to have communication problems.... Prover? with the autocom...

Thank you for the information and maybe keep in touch to exchange information.... Having vehicles that are very similar, we can certainly give you a hand....
See you soon.

Tieri in mind that I do not use the 1260 to program... they were just tests I did to see if it worked and, above all, to make you understand that if it works, he must also work your, and then you're doing something wrong !!! p.s.' autocom is a diagnosis, not a programmer !

Still good job ! hello Alessandro

Thanks Ale...

I feel stuck with my but up to this point... I Meant to say that prover? to read the DTA buying an autocom....

For the map I have to find someone more? expert me to explain in a few steps as I do for reading why? probably something wrong....
