Hi all,
I'm looking for some advice about a 2017 BMW 440i. The turbo is making a fairly loud whistling sound when it spools and I have major loss of power. Does this mean I have a leak somewhere? The car is still drivable but makes very little power. Thank you! Edit: I have a high flow cat, Dinan intake, and was running jb4 on map 3. MPPSK |

My understanding was map 3 was the least aggressive?
Edit: found this from Mike on an earlier b58 post I used as reference. Is this true? "Map Guide as of v4 firmware below: Map 0: Disable JB4 all together Map 1: Suggested performance map Map 2: More aggressive than map1 for bolt on mods and higher octane fuels or octane booster, currently in BETA testing Map 3: Less aggressive than map1 intended for use with lower grade fuels or customers looking for less of a performance increase. Map 4: Stock tuning with CANbus active for logging and diagnostics Map 7: Water/Methanol Injection map" |

Those are old maps. Current maps are 1 is +3 psi, 2 is +4 psi and Map 3 is +6 psi.

Can you provide any more details, did they say what caused the failure?

8-10k; that’s nuts. If this happened to me out of warranty I’d go Pure Stage 2 for $2250 and pay a BMW Indy $1200 to install it.

Update:
Bmw is refusing warranty service on the turbo due to "external influences". They're blaming that the Dinan intake is missing a bolt. However; I installed the intake and didn't install the last bolt because I was missing the nut for it. It did not impact the install whatsoever. We'll see what happens now. Edit: Once I explained the situation with the bolt, everything seems okay for now. They're proceeding with the diagnosis. |
