I just bought the car off another member and started tuning it, car was running great decided to try my luck with an M6 and LIMP mode came on 30FF code. Now I have zero boost. Checked everything on it and replaced boost Selenoids also.

Anyone know a reputable shop to get new turbos installed?

[arhoads335i]

Like no boost at all?
you should look at intercooler boots, vacumme lines and charge pipe O ring.
Seems odd that it was great and all of a sudden no boost.
But I have great luck with matt@ZNMPerformance

Most likely a blown chargepipe or vacuum line. Can you clarify on your 'checked everything'?

Turbos don't just go like that, they will show signs of failure (white exhaust fumes is the primary indicator) before outright failing. Plus you have two of them, both failing at the same time is unheard of. There are plenty of threads outlining how to test pressure leaks, I would start there if you're mechanically inclined, if not any reputable shop that knows these engines should be able to diagnose quickly.

I upgraded all my vacuum lines, my charge pipe blew two weeks ago replaced with an aluminum Cobb one, I just replaced my boost Selenoids, cleaned my vanos Selenoids. I do have upgraded intercooler and JB4 but no white smoke

[arhoads335i]

Look at the vacuum canisters closely or remove them all together.
If there is no smoke then your turbos should be good but it's possible your waistgates got stuck open.
You sure someone didn't swap it for a 328i haha
Maybe JB4 put you on the wrong map.
Id look at the intercooler boots again or maybe the outlet pipe came off? that is rare though.
Also could be a failed diverter valve if you didn't upgrade to a BOV

Do you have a boost gauge or JB4 connect to monitor boost levels? You stated no boost, but is it possible you just have low boost?

I would start with checking the chargepipes (upper and lower) to make sure everything is good there. Are you still using the stock diverter valves? Those can fail under increased boost and would lead to a no boost situation.

If no issues with the above, then I would recommend uninstalling the JB4 to rule out any issues there.

What do you mean by "M6"?

No boost gauge I use the JB4 to tell me the boost level, I am using stock diverters so I may have to go forge for those.

Going to check everything again and update as of this weekend.

And you're getting a 0 psi read from the JB4? What's the year & mileage of your car?

I have stock DVs myself and will go Forge as soon as the stock ones become an issue.

So after taking the car apart and looking underneath for vacuum leaks. I take apart the T connectors that go to the boost Selenoids and one of them is burned all that for a T connector

you said your chargepipe blew, did you get a new C-clip and O-ring?
