I have a E90 325d 2007. Lately it has started to cut ( I mean shut down and barely manage to keep the engine going)

It happens if i have somewhere between 50-100% throttle, and are going past 3300/3500 rpm

When it happens i have to swith ignition on and off to manage to driver further.

I use a Delphi diagnostic tool and found the following fault codes

3FC0 - Airflowsensor
3FF1 - Airflowsensor
438D - Throttle Actuator
4212 Glow plug 1
4232 Glow plug 2
4242 Glowplug 4
49A2 Weak AC cooling
426E Intelligent Battery sensor

3FC0 - Airflowsensor - I have tried 2 different sensors, same fault
3FF1 - Airflowsensor - I have tried 2 different sensors, same fault
438D - Throttle Actuator - Seems to be working fine, have also disconnected it, and it doesnt affect the cutting at all
4212 Glow plug 1 Guess these are just for starting anyway
4232 Glow plug 2 Guess these are just for starting anyway
4242 Glowplug 4 Guess these are just for starting anyway
49A2 Weak AC cooling - Dont have GAS on the AC system
426E Intelligent Battery sensor -

Anyone experienced anything similiar?

The car is btw tuned to abt 250 hp, but it behaves exactly the same with or without the tuned map

So, how old is you battery? I've seen these cars throw all kinds of codes when the battery is on its last legs or was replaced and not registered properly. I see you have a 426E which could indicate a bad battery which would wreak havoc on everything else. Or your IBS which controls charging could be bad.

i know for fact that my ibs is faulty, and the battery is good

To clear the 3FC0 and probably the 3FF1; you need to reset MAF adaptions in Rheingold.

I had the 3FC0 fault after cleaning my MAF.

From memory there may also be a throttle actuator adaption as well.

Rheingold will give test programs to help identify and resolve these issues.
