My 335xi is going in for its 1st service. What is the consensus on the new software?

I've read that there are problems with the new software upgrade. Will the dealer give me problems if I tell them not to alter the software? How bad is the turbo lag? TIA

I didn't try and refuse the new software so can't answer that part of your question. Regarding turbo lag, there is a bit more when flooring it at low revs but nothing noticeable at medium or high revs. If it had been done without my knowledge I might not have noticed it but I was looking out for it from forum comments. The exhaust pops and burbles on the over-run which it didn't used to to, and the vacuum-operated flap in the exhaust sometimes makes a metallic noise - both of these are because of the new software. The fuel economy is improved a bit. If the software has been changed to protect the longevity of the engine then the dealier might give you a hard time if you refuse.

You may only have to deal with the lag for a few months.

They won't update the software unless they have a reason to. If you're going in for maintenance, then there is no reason to update the software. They'll only update it if you tell them of a problem in which programming is part of the repair.
