The hang-up with post-2003 X5 software products from Dinan was that BMW switched to a valvetronic engine. For the past three years Dinan has been working through each of the BMW models building new code for valvetronic engines and transmissions (engine software must be developed prior to tranny software). They have completed many of the new cars (545, 645, 550) and are now finishing the 650i's software code set.

Next up: E53 X5! They estimate that within 3 to 6 months they should have the engine and transmission software complete. I informed them of my X5 trying to hold 4th gear (unless I really mash the gas pedal) as I slow down to 20MPH to round a turn. They said the improved throttle response (engine software) and slightly more aggressive shift points (transmission software) should help.

I put my name on their list of buyers once these get developed. I expect a call by mid-summer. Maybe if we all call to get our names on the list it may prompt them to complete this effort faster due to demand. They have a 4.4i in their lot just waiting to be used for development...

Their phone number is (800) 341-5480. Extension 1, for Sales. You can either speak to Scott in Sales or Eric in High Performance Tuning. Just get on the list

Exact same issues here on my 2006 4.4. I will call on Monday to put myself on the list!
