I just installed a GFB DV+ on a 2010 MCS with evolve tune, FMIC and large exhaust.

I can definitely see a difference in the boost gauge during shifts and feel less lag and quicker pull during shift.

I do hear the flutter that the instructions talk about during low speed shifts.

The problem is that after I make a full power pull after the last shift it goes into half power mode and using the app "BMWhat" its showing a idle MAP pressure fault.

I recycled the motor on the fly and the fault went away, and was wondering if it would just go away on its on.

Any ideas? pull the DV and lube it might it be sticking? Change the MAP sensor to JCW or something else? (althouigh I would expect the sensor is just reporting higher readings and its the ecu seeing something it doesn't like)

BMW fault 28aa. Diverter plausibility?

 

Although no expert on it, it does sound like a tune problem. Plausibility means that it is reading a value, but it is not within the expected range. So the sensor is not the problem, but the ECU tune. I would expect the sensor to be the exact same part on the JCW.

 

Going to play with springs and the piston (lube)

No issues before this add with either the wmw valve or stock with this tune

 

I have a wmw upgraded diverter solenoid (no part number on case.) With the db+ it makes a noticeable chirp when it activates. With that solenoid I get the fault and can recreate it on demand.

I put my stock Diverter solenoid on and the sound is definitely different. No flutter at low speed and no fault.

I even switched back again and the faults came back immediately, switched to stock solenoid and the fault disappears .

Not sure if bad sol or crack leak something but it worked fine without Dv and faults with

 

Talk to Battle Tuning as their the "official" distributor of the GFB DV+ here on the forums and they might know what could be causing it. Also talk to Evolve and see if the tune they sent maybe didn't account for an uprated DV.

 

With the last post it's fixed and runs great with the stock solenoids and the dv+.

With the way motor works solenoid and dv+ it causes a fault

I don't think evolve can tune for the wmw combined with the dv

There is definitely an actuating difference between the way solenoid and the stock one.

 

so I know this was four years ago but if you are still about, I have the same issue!

Can I ask what you did to fix this?

thanks.

 

it says above that he put the oem solenoid on instead of the wmw upgraded solenoid. Im using the oem solenoid attached to the gfb dv+ and an rpm stage 3 tune with no issues

 

Whats the part number for your solenoid? My tuner Mario said my gfb dv+ didnt work with my stage 3 rpm tune.

 

Hi Kupona, thanks for the reply.

My part number was T9352.

I bought a new Diverter and tried that with the GFB DV+ but still the same. I have installed the new Diverter on it's own and the power is much better than before, so I know my first Diverter is not operating correctly but I need to confirm if my DV+ is faulty too.

 

i have the oem solenoid and the part number for my dv+ is T9352.

 

No the part number for the OEM recirc valve/solenoid. You use the OEM solenoid to attach to the GFB system, i am asking what the part number on that MINI OEM part you have is.

 

I don’t know the part number, it was on my car from the factory

 

The one that was on mine was 7.01115.05.

The new one is 0.1115.08.

Cheers.
