dct installed.
so when swap was finished, i drove to make some test riding. for about 30km i've got fault codes few times.
this problem was seen only when i drove in two legs (one on brake and one on gas), and tried to start acceleration immediately after braking. so then car lag for about a second or two, and gave a fault on dash.
long story short, it looked like oil starvation. oil level was good, like manual recommends.
but, i saw in ista, that on m3 gts, dct takes one liter more.
transmission fully the same on both cars - so no different in oil volume to the level plug.
they won this problem simple and easy - where level plug locates, they fits banjo, with end turned to the top. so, you need to top up oil like always, before it goes back, and then, you fit this banjo and top up additional liter thru the end.
after that you'll get oil level higher that usual, and chances for getting oil starvation reduced.
so, i needed to test this assumption, and i was jacking our 135 on one side and topped up this liter without any banjo
tests after that shown that problem gone.
