Default Stock 335i Lag Issues Below 3krpm? - 10-19-2020, 04:40 AM

Hi All,

I have a E93 on 67k with the factory fit turbos.

I get no fault codes or anything but if I out my foot down in 1st (auto) there's next to no power before I hit 3k.

BMW have confirmed wastegate omegle xender rattle on startup but not when driving.

The car cannot break traction with traction control fully off, including brake boosted starts.

Post 3k it takes off like it should and no codes are thrown up.

The software on the DME is IEZ1S.

I'm pretty much stuck as BMW claim all is well and nothing is wrong with the car.

I think the software on the DME is limited performance below 3k to mask wastegate rattle issues.

Any ideas?

I have heard of BMW software to mask rattle and people noticing lag. Maybe that is what you are experiencing.
Jb4 on the car ?
