problem starting to warm audi a3, golf 5, etc..

[giulianoA3]

hello all, ? for a while that I hear about this problem, but I do not know what is due, immaggiono stuff electronics!!!
on my audi a3 8p old I had the problem of cold start, but the problem was due to the head, another problem that plagued these cars, recognized by audi..
now I have always taken a latest version of the a3 2006, with dpf, that I would like in the short-delete it!!to be honest, the older version was better!!boo!!

[magi1984]

the problem, according to a technical bulletin that VW ? due to the starter motor that loses performance and wear of the battery.
in fact, the technical bulletin says of change in these cases battery + starter motor

the truth? ? with a simple touch in the map that resolves the problem and the car owner save a p? of soldini

[giulianoA3]

ok, then the change consists in the modification of some maps, for example, are lowered down payments?or on the contrary?or is injected more nafta!!thanks!!

[magi1984]

is simply injected a bit of diesel in the pi? in the map that manages the starting of the cold engine

[-David-]

The Cio? just a slight increase in the mg diesel fuel-injected, cold, and resolves the problem of' hot start? I understood it well?

virtually you!!!I believed that you were increasing the advance payments, as you would in the petrol, but the diesel is not ? the same thing..

[magi1984]

in edc16 and 15 vag, I think, edc17, there are two maps for the goodwill, use it to motere cold, the other warm the engine. The diesel increase it on the map of the hot start that ? where the defect

[giulianoA3]

hello, I have heard that this problem also occurs on the golf 6, is resolved in the same way?possibly this version of golf can be read with mpps v. 12?thanks..

[magi1984]

always in the same way, but I don't know if mpps the fa or not

[giulianoA3]

it would be the one to try!!!

[magi1984]

it would be simply to check on the list of cars of mpps :)

[msport (exil77grande)]

from what I remember mpps law the edc17 vag but then you can riscivere a mod because it doesn't do the calculation of ck in automatic then the machine will not run and you have to rewrite the file ori bed earlier also I don't know about you but I think 2 times before writing a edc17 with mpps.

[magi1984]

I as well :D

the alternative to mpps for this machine, what would it be?

[msport (exil77grande)]

the alternative to mpps for this machine, what would it be?

if we talk about clones fg tech v2 otherwise official tools.

[scarface]

but has anyone ever tried to write a edc 17 with mpps?

[msport (exil77grande)]

but has anyone ever tried to write a edc 17 with mpps?

there are those who he did it with the v5 and in practice, it is verified what I have already written that it reads the file ori then the mod written does not compute the ck and not part then rewriting the file ori part.

[magi1984]

b? if ? only this calculate the cks on the file before writing it would not be a big problem...

[msport (exil77grande)]

I agree with you, but the test with mpps who makes it?

heheeh I'm not sure.

[explode82]

well I know who has done it ,but with v12 and calculating the cecksum with winols,I would not have ever done

[Ross]

In fact, and this only happens on cars with ecu Bosch, the first 3 curves related to the map injection to cold, are zero. Just copy the first 3 curves from the second map injection cold on before and it resolves.

[rocalci]

from information received from a**** workshop vw, the vw has adopted in ucu a working strategy that injects diesel fuel if the engine does not reach the 250 laps...
and ? for this that they make you change the battery and the starter, because it is enough that the battery lost a bit of efficiency, or the starter motor takes a bit of slack in the bushings, and spin a little more floor, the ecu will not inject fuel, then just change the map and the problem is solved in 10 minutes with a net-savings to the customer

Not all of the idea to change the ecu mapping to solve the problem,so many before you do pluck replacing the battery and starter motor
start-up and only at the end when the defect continues to be to mod the ecu

[rocalci]

Already, unfortunately, they are too suspicious ... and spend triple the amount not to fix anything or better to dab a bit of time...

[magi1984]

to me have happened to a couple of vw that despite the change in the unit continued to have problems starting when warm, and in the diagnosis, both before and after the change gave the error on the phase sensor. In those cases, the problem is not ? due to the map but ? of a mechanical nature

[rocalci]

well ok but what ? a particular case where you ? spoiled a sensor

[tezzero]

Without remapping the ecu, there are five add-on modules that connect to the 5 volt on the engine temperature sensor. also when the engine ? hot the control unit receives the information as if it were cold(the signal remains at 5 volts) and the car starts..then once in motion returns to normal..

It is the little to solve the problem of departures and a lot of that exists,but has nothing to do with the work done on the map,another planet

[rocalci]

already the little tricks the temperature sensor....

[munro]

yes, but have you ever heard a vag starting cold with the little??
it seems that the engine has the injectors staratissimi as it vibrates and limping...then? hot system....I say that ? a thousand times better than the mod in the ecu....

[legendaryslave]

quoto those who have said to change from map to resolve the 99% of the cases

[tezzero]

yes, but have you ever heard a vag starting cold with the little??

With the modules that I used never had a problem..obvious the map ? best... but if you find it difficult to read and write an ecu ? always an alternative way to solve the problem..right??

[rocalci]

also because, cold should not be any difference in start-up, since the module communicates to the ecu that the engine ? always cold during the start-up

[tezzero]

In fact..***** and I repeat to me no problem..

[tezzero]

Remember that a customer with a samsung before series engine vw 1900 tdi AFN I even sliced off the 5 volt and the car ? went well and for the absurd without light injection on..strange but true!!

[munro]

I of those modulini taken in germany, I have fitted a few on cars of friends, and in addition to having the problem mentioned went also a p? more I believe that a dozen horses take them with that contraption...honestly for? it could be that the ones I mounted I was slightly different because I felt many say that it was enough to put a transistor from the non-s? how many ohms to get the same effect and I was curious about there? I opened one of the forms of thinking he found a transistor, but I noticed that inside there was a real circuit...

[magi1984]

not ? a problem of phase sensor failure rocalci why? the car in the cold part perfectly, the only hot has the goodwill along
