N20 Turbo won’t have spool noise
Hi,
I have a 2015 320i with N20 engine and about 50k miles, with a delete catalyst converter, GFB DV+, a cold air intake with K&N filter and I’m running with stage 1 ACN 91 OCT BM3. Yesterday I was entering in my garage and ban the throttle responsiveness was lower than in ECO mode, I’ve tested with the BM3 scanner and appear the 180001 Catalyst: efficiency below limits (won’t turn on the engine light), so I’ve delete the code and start the car, the throttle responsiveness came back, but now the car is running strange, looks like do not have turbo pressure on low rpm and the turbo do not spools anymore… I’ve ran some BM3 datalogs and do one small pull (at my on risk and very scared), but everything seems pretty normal, it have like 18psi as the previous datalogs, the MAP and MAF also the same. No strange noises. Do anyone already see that??? It not have any code or engine light on… It thinking that have some pretty small inlet leak… |
