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.

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 motorQuote:

Already, unfortunately, they are too suspicious ... and spend triple the amount not to fix anything or better to dab a bit of time...
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
well ok but what ? a particular case where you ? spoiled a sensor
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 planetQuote:

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....
