i picked up my 2018 340 a few weeks ago. the maintenance plan ends this november, and car is up for service now. (oil, air filter, microfilter (which i assume is cabin filter)). it's the last time service will be covered so obviously i'd be inclined to have them do it, free is free.

however, i also want to flash bm3. I checked with PTF and my software levels will allow for flashing without bench unlock. but of course, if bmw updates, i'll likely be locked out.

so i want the maintenance, but i don't want them updating the dme. on a routine maintenance, would they update it? can i ask them to ensure they don't update the dme?

They don't at my dealer on the maintenance plan. I was just in last month. When I go in, I do flash and lock the stock tune and dme.

They will ask before updating the ECU unless you are having issues with the car that needs an ECU update.

To be safe, I always ask them not to update the ECU without getting my permission first

thanks guys.

while i'm on the topic, I have 57,000kms on my car. assuming the plugs were never changed, should they be changed at this point, before i start running a bm3 map? and if so, during the 4 year maintenance schedule, are plugs normally changed somewhere in that timeframe (i.e. now for me, since im' towards the end of the 4 year mark)

yes it is time to change them either way

thank you. it's tough to get a clear idea of spark plug change interval by searching online.

since I bought the car from the dealer used, I'll just go there for maintenance and press them to do the plugs as part of maintenance as best I can.

it's the least they can do considering I bought the car from them

according to BMW here, they said 90k for the plugs. and because the car isn't notifying they won't do them.

57,000kms is only 35,000 miles. Earliest Ive seen BMW say to replace plugs is 40,000 miles with the mppsk. But if you diy I would do it at 30k miles.

no issue diy really. I've done it on my other cars in the past (Mazda and ford). only difference is this is alot newer, and more expensive .

but I've watched some videos and it doesn't look all that bad. I watched one video where the guy somehow got all the way to the back plug without removing anything but it looked pretty awkward and tight.

I'm guessing a couple hours the first time. and probably an hour tops once I get used to it.
