Thanks bro. Looking forward to it.

Kapag naka off yung AC or yung compressor nawawala yung whirring sound and slight gas pedal vibration at 1000 RPM. Technician also informed me na marami ng nakapag sabi rin sakanila ng ganitong occurence and narelay nadaw nila sa planta. They're currently waiting daw for a TSL (Technical Service Letter) from Mitsu PH regarding kung anong gagawin about this pero rest assured naman daw sabi ni Mitsu PH na walang magiging problem whatsover sa vehicles natin kahit may ganitong occurence. Nataon din kanina may 3rd Gen Monty ding nagpapaservice which was at 25,000 kms na and we tried that unit din while it was stationary and same lang occurence sa unit namin which is fresh pa (less than 70kms pa on the ODO). Will update ulit sa thread nato sakaling may balita ako.

Any update on this bro?

I also have this low rpm noise in my 2018 Monty. Whirlwind sound around 900rpm.

From the forum thread shared by erwindc22:

Well, it's taken a while but it's fixed. Like a story? Read on:

I took the car into the dealer mid August, described the problem, had the expected response of 'Oh, it'll be the air filter vibration', and I guess the first thing they tried was replacing the plastic clips holding the air filter pipe with self-tappers. Checking afterwards, that tied down the air filter a bit, but didn't get shot of the most irritating noise in the world....

Apparently the garage then had two guys on the job for most of the day a.) trying to reproduce the noise on the ramp and b.) trying to see what fixed it. They found that it appeared to be a faulty engine mounting, and a new one was ordered - that'd take a week or so as it was a special order item - which it then turned out no-one had ever ordered on in the UK before. Well, I could have walked to the factory and back in The Netherlands and got it myself in the 8 weeks it took for the part to arrive!

So in mid October the car went into the new engine mounting and...... wait for it...... no change, noise still there, I think the service manager was as gutted as I was! Three weeks later the car was in for it's 12,500 service and with some information (photos, description, etc.) supplied by Mitsi UK, the noise was finally eradicated. A bracket holding the intercooler can get bent under the torque of the engine causing the vibration and noise (presumably in connection with something else at the same time - large bump in road etc.).

So not only has the off throttle noise at 1500rpm gone, the loud roar from the air filter assembly under load at the same engine speed has gone, the engine is hugely quieter now!

So a big 'hats off' to Oak Tree Garages in Coventry for sticking to it and solving the problem when I guess many others would have given up! I've finally got the car I was expecting!
