W208 Not shifting up When Cold

[steveoelliott]

Hi all,

I already happen to know the trigger / cause of this problem as a specialist resolved it for me previously.

This issue is most prevalent when the car is cold. I notice that when the gears do not shift up the orange light around "D" is not illuminated (need lights on to see this normally). If you wiggle the selector until "D" is orange then the gears start changing up / down normally.

The specialist previously replaced something to resolve this but 4 years on it has returned.

Any ideas what the part replaced may be? I don't have old invoices or contact details.

Thanks...
