It has been a while since I heard this type of problem :) We used to see this quite often at the dealer. The fix for this is a programming of the transmission which boosts pressures in the transmission. This is something that would have to be programmed by the dealer. There is also a service bulletin on this problem and is a known issue.
The one catch is if the programming was already performed. If so, and the problem persists, this would indicate an internal problem in the transmission and a replacement or rebuild would be needed.
However, most often this is easily corrected with a programming update. The SIB description is a delay on cold start when selecting Drive or Reverse.
I hope this information is helpful. Please accept and best wishes to you on your repair. Thank you.
Both people are somewhat correct in this.
You can continue to drive the vehicle. I have not heard that it causes any damage, but that it is just annoying at times.
In most states, the dealer is responsible for the vehicle to run correctly within at least a 90 day window. That might make this a responsibility of the dealer to correct. It depends on the conditions of the sale. I have seen that a few of these vehicles have not been programmed. The dealer should cover the cost for at least the programming for you as you just purchased this vehicle. The cost is low for this and it is only a 1 hour labor charge. If the problem persists then they sold you a vehicle with a transmission problem and it would be good to identify this quickly so you can take action if need be to return the vehicle or have them correct it. At my dealer we had to replace a trans. with the cost going to sales for this exact type of problem.
But I have had great success with correcting this with just the programming. I would recommend having this performed so you know the state of the transmission.
I hope this is helpful. Please accept and best wishes to you.
Glad to help further. I do not think a tune up will correct this problem as it is known problem that is usually fixable with the programming.
However, a tune up is due at 100,000 miles. Spark plugs are due, an inspection II which includes engine air filter, AC microfilter, and an oil service. I would have the rear differential fluid replaced. That is something most people miss. Replacing the transmission fluid is usually done at 100,000 miles. The fuel filter is a good idea as well at 100,000.
BMW recommends to replace the 02 sensors as well at 100,000 but in my recommendation, I would not replace them until they fail. A check engine light will come on and you can replace the sensor as they fail. Sometimes they can last quite a while.
For the transmission issue, just tell them about the transmission delay from park to drive on a first start. Tell them to use SIB 24 07 03 which outlines this problem in a service bulletin.
