| Sveiki!
Braucu ar e90 325D 2007 automātu. Vai kāds ir saskāries ar šādu problēmu: apstājoties ar mašīnu un turot bremzi ilgāk par 10 sec, kad startē, ir tāds kā trieciens/sitiens uz uzsākšanu. Ieliekot kārbu DS režīmā sitiena nav tikai uz D. Lasīju netā, ka to varot atrisināt ar "Disabling the NIC in the EGS".
Ar mašīnu braucu jau 5 gadus un tā ir kopš sākumiem. Agrāk, kad uzsila mašīna pazuda, bet tagad ir visu laiku.
Varbūt varat ieteikt kādu programmētāju ar kuru varētu pamēģināt šo metodi?

As part of a Service Bulletin SI B 24 03 08 issued Jan 2009.
SUBJECT
E9x, E6x with 6HP19TU - Jolt and Delay when Pulling Away
MODEL
E90, E92, E93 (335i) with N54 and 6HP19TU from 03/07
E60, E61 (535i) with N54 and 6HP19TU from 03/07
E60 (528i) with N52K and 6HP19TU from 03/07
SITUATION
The customer may complain of a delayed engagement and a harsh jolt when accelerating from a stop.
The situation occurs only during the engine warm-up phase (cold engine), and cannot be reproduced in the Sport Mode.
CAUSE
EGS software (unfavorable NIC – Neutral Idle Control) calibration
SOLUTION
On a customer complaint basis only, check the vehicle's integration level.
If the integration level is:
On E9x vehicles - E89x-07-06-520 or lower
On E6x N54 vehicles - E060-07-09-530 or lower
On E60 N52K vehicles – E060-08-03-550 or lower
Reprogram and recode the complete vehicle with a current Progman version (target levels are E89x-07-
09-518; E060-08-03-510; and E060-08-09-520, respectively, for E9x, E6x N54 and E6x N52K vehicles).
Important Note:
The NIC (Neutral Idle Control) feature disengages the torque converter from the transmission when the
vehicle is stationary in the Drive position; the service brakes are applied; and the engine is still in the warm-
up phase. The NIC function eliminates engine load when vehicle is stopped, reducing fuel consumption.
Although the EGS software changes (as listed above) are improving transmission comfort feel while still providing the benefits of the NIC feature, they still may not be acceptable for the most discriminating customers.
In such a case, on a customer complaint basis only, deactivate the NIC function by performing the "Converter lockup clutch" retrofit, using the current Progman/ISTA P version.
P.S. Pietika tikai ar kārbas atjaunināšanu un nav obligāti jāatslēdz NIC. Cik saprotu šis risinājums der 6HP19 kārbām.
