I May be missing something here but I can,t seem to see any place to enter time zone. Any way Courtenay BC Canada is at sea level and in the pacific time zone.
What may be the problem is that I have a new computer and when the power goes out here, which has been often due to recent storms, my computer defauls back to Jan1 12:00am 2001 and I dont notice the change I will change it back to the right time and see if that helps.

I will look up the ALDA thing
Re; post about testing for first gear there is no right or left slots in the 2 position and it does start in first gear. It does shift from 2nd to 3rd very quickly ie spending only about a second in 2nd gear. This may be a normal thing though.

I finally contacted a reputable Mercedes repair depot in Langley who emphasized that this car should not have any less power than the 80. He suggests that a valve adjustment is the first step. The slow acceleration at low speeds he claimed is a injection timing problem . He will reclock the timing pump which can be be moved 1 or 2 steps without taking out the pump. Further reclocking requires removal of the pump which will be more costlybut reasonable . Does this make sense?
