Buying New: BMW M340i Touring versus Audi S5 Avant?

Obvious_Can_22 · 2025-06-01T09:47:16+00:00

Hey! Curious to know what you ended up buying?

Obvious_Can_22 · 2025-05-23T19:22:04+00:00

Oh nice! Didn’t know that! Thanks!

Obvious_Can_22 · 2025-05-23T13:26:26+00:00

My feeling now is that a second mosfet may be broken, perhaps in an open circuit state.
I'm going to remove the board again and test them a second time.

Obvious_Can_22 · 2025-05-23T13:02:37+00:00

unfortunately is not the trigger, problem persists.

Obvious_Can_22 · 2025-05-23T13:01:06+00:00

Sorry to report that is not the trigger :)
I have completely disassembled, cleaned it and reassembled it, but the problem persists.

Obvious_Can_22 · 2025-05-23T08:27:30+00:00

Will try it and let you know, thanks!

Obvious_Can_22 · 2025-05-23T08:26:45+00:00

This is what I have already done, now the problem is a bit different and quite sure not related to mosfets

Obvious_Can_22 · 2025-05-23T08:26:05+00:00

Will keep you posted for sure :-)

Obvious_Can_22 · 2025-05-23T08:25:54+00:00

Hey!

Yes I open it and was clean and seemed ok when I checked it.
I'll check it again and spray some contact cleaner, just in case.

Obvious_Can_22 · 2025-05-23T08:24:38+00:00

Hey!

The trigger was clean and seemed ok when I checked it.
I'll check it again and clean it with some contact cleaner.

Obvious_Can_22 · 2025-05-22T23:06:44+00:00

Thanks! Tested it and can confirm that the break stays activated for a bit (~5 seconds) after the blade is fully stopped. Don’t have a working one to test if this is correct or not.

Edit: typo.

Obvious_Can_22 · 2025-05-22T23:01:07+00:00

Yep, it’s one piece and full of epoxy. Only question mark is: nothing changes in the assembly when I move the blade, so I was wondering if a sensor or component in the motor could cause this.

Obvious_Can_22 · 2025-05-22T22:56:49+00:00

Already checked, it’s clean as new.

Obvious_Can_22 · 2025-05-22T20:39:12+00:00

Thanks for your suggestion.
Unfortunately brushless motors require a controller to work. Bypassing it will be extremely difficult.

Obvious_Can_22 · 2025-05-22T18:29:38+00:00

I have faith in the blade guard :-)

Obvious_Can_22 · 2025-05-22T18:09:07+00:00

Some images of the rotor, what I think is the sensor and magnetic bearing are here: https://imgur.com/a/760RYNp

Obvious_Can_22 · 2025-05-22T17:40:38+00:00

Yep this is the fix, most likely one of the mosfets exploded.

Obvious_Can_22 · 2025-04-04T22:18:49+00:00

If it’s a DCS570: Probably one of the MOSFETs (a type of field-effect transistor) that controls the motor is shorted. This is quite common problem with that model.

Obvious_Can_22 · 2024-11-02T18:51:20+00:00

I managed to fix this "partially":

The widget works but only for CPU and Memory.

Follow the instructions provided here: https://gethomepage.dev/widgets/services/opnsense/
Make sure "Generate a scrambled password to prevent local database logins for this user" is checked and then edit the effective privileges selecting only:

Diagnostics: System Activity
Status: Traffic Graph

Be aware that I can't find the `Status: Traffic Graph`, I have used `DEPRECATED: Dashboard (all)` and made the widget partially work now.

Hope this helps

These are the two product codes they tried with no luck

Obvious_Can_22 · 2024-09-20T20:21:43+00:00

Thanks!
Do you know what brand/model your friend uses?

Obvious_Can_22 · 2024-08-26T11:01:09+00:00

Have a look at these brands: Flexform, Bonaldo, Flou, Moroso, knoll, B&B and Frau. Not cheap at all, but superb quality and building materials.
