I know that the diagnostic tool is used to reset the oil counter (electronic). And if you don't do this then you might have warning lights on the dashboard. And the gearbox paramaters isn't able to change to suit the new oil.
I personally don't believe that the four speed gearbox on a my car is so advanced that it is crucial to the operation of the gearbox. Must be much worse not changing the oil at all. The point of changing the oil is to make the gearbox last longer.
So when you change the oil without using a diagnostic tool will this in any way cause the gearbox not to function (I mean not being able to drive the car afterwards) ?
So you don't think your gearbox is advanced?
S - "normal" operating laws.
T - Gearbox reheating and protection laws.
" 1" Programme selector connection.
" 2" Gearbox oil temperature information.
(L1) Economy pattern.
(L2) Medium law.
(L3) SPORT pattern.
(L4) BRAKING pattern 1.
(L5) BRAKING pattern 2.
(L6) DESCENT pattern.
(L7) SNOW pattern.
(L8) Unlocked pattern.
(L9) Heating pattern.
(L10) Thermal protection pattern.
The ECU uses 10 selection laws :
- 6 Auto-adaptive laws
- 1 Law specific to the "snow" program
- 1 Unlocked pattern
- 1 Engine and gearbox reheating law
- 1 Gearbox Overheating Protection pattern
If the "sport" and "snow" warning lamps flash simultaneously, it signifies:
Presence of faults in the system (3rd hydraulic, also known as the "emergency mode")
- That the gearbox oil has overheated
- That the gearbox oil is old
It's your choice of course if you decide not to do it - but you have been advised.
