r/BYD

Latest update, messed with seat memory.
So now thats not working, and the icons are gone.

Anyone know of hotfixes coming?

I got my BYD Atto 3 about a month ago and I’m trying to connect the mobile app to the car.

The dealer told me the QR code should be available by the end of the following week, but that was about two weeks ago. Since then they’ve just been saying they’ll “look into it” without giving any updates.

Is there any way to manually get the QR code to appear in the car menu? I am honestly fed up.

Thanks!

The new features:

One year in, and this is still my biggest daily anxiety with the Seal: the front overhang and ground clearance.

Compared to my previous car, the Seal sits quite low. Every time I tackle those aggressive, square speed bumps in London boroughs or encounter uneven country lanes in the countryside, I hold my breath. I’ve had a couple of nasty "crunch" sounds from the plastic air deflector underneath when moving at what felt like a snail's pace.

Are you guys diagonal-driving over speed humps, or has the suspension softened up enough over the year to make it less of an issue? Just want to check if I need to be even more paranoid than I already am!

I have a byd atto 3 2023 and no matter what when the car is turned on android auto will refuse to close, I sometimes just sit in the car and watch to go on tiktok or somthing without the sound be connected to the car so I go to turn off android auto and i just can, I tried from the car and it just reconnected, in the phone there is no disconnect option, I try to disable Bluetooth on both the car and phone and it just activated on its on like wtf, I don't want to remove the pairing because its just a hassle to do each time, is there any solution?

Is the SEAL 5 DM-I PHEV a good first car for a family of 3? Does it have level 2 semi autonomous driving (ADAS)? How is its comfortability?

It seems like lots of good news are published about BYD. Rising international sales, charging technology advancements, etc. But the stock is only going down. Why?

Hat jemand schon persönliche Erfahrungswerte zum Atto 2 Comfort?

Ich schwanke aktuell zwischen dem Astra Electric ST und dem Atto2 comfort. Der Seal ist auch interessant aber für Familie mit einem Kind mit Kinderwagen ist der Kofferraum wohl zu klein.

Vor allem interessiert mich die Reichweite - ich habe auf YouTube Videos gesehen, wo der Atto2 auf der Autobahn keine 200km schafft, aber das war noch mit der 40kwh Batterie.

Aktuell fallen mir die Entscheidungen nicht leicht, da das Auto schon auf 10 Jahre angelegt sein soll.

Bei BYD finde ich gut, dass ich für Navi mit Ladeplanung kein Abo brauche und die Planung über Google Maps läuft. Wenn wir aber Mal Verwandte in 90km einfache Entfernung besuchen, würde ich das gerne ohne zusätzlichen Ladestops schaffen können.

I’m having trouble enabling ADB after downgrading my Dolphin to version 2503.

From what I remember, you’re supposed to go into Settings, tap the software version multiple times, and then you get access to the menu where you can enable ADB or grant ADB permissions for certain apps/install APKs.

But this time, that menu never appears. I also tried the usual *#9xxxx dialer method, but instead of opening the menu it just shows a QR code even after downgrading.

So I thought I’d come here to share my experience after owning a BYD Seal U DM-i.

Back in October, I went to my local BYD dealer to purchase a Seal U DM-i. I test drove the car and initially thought it was brilliant. The amount of technology you get for the price is genuinely impressive, and I took delivery within the same month.

However, after around 4–6 weeks of ownership I started noticing a few things:

1. Very loud/rattly suspension noise
2. Misaligned body panels
3. Small paint imperfections on the bonnet
4. “No video signal detected” occasionally appearing when selecting reverse

At the time, I decided to monitor these issues and planned to raise them together at the dealer after a few months of ownership rather than making constant trips back and forth.

Unfortunately, the biggest issue was still to come.

In late December, I noticed a loud rattling/clunking noise from what sounded like the driver-side wheel/drivetrain area whenever turning right under load. I immediately contacted the dealer to get the car booked in.

The vehicle was initially booked in just before Christmas, but the dealer then contacted me to say their BYD warranty/computer system was down and they could no longer look at the vehicle on the agreed date.

Something about this didn’t sound right to me, so after several phone calls I ended up driving to the dealership directly.

A mechanic came out for a road test with me, confirmed he could hear the noise, and after inspecting the vehicle advised there was slight play in the driveshaft and that it required replacement.

The issue was that, due to the “system being down”, they still couldn’t process the warranty repair. So I was left driving a brand-new car with a known mechanical fault over the Christmas period for over 200 miles.

The vehicle was eventually booked in for repair on 13 January 2026.

I was given a courtesy car and later informed the repair would take longer because the required part was delayed. Interestingly, I was now being told the vehicle was not safe to drive — despite previously being told it was safe over Christmas.

The dealer had the car for 10 days to replace the driveshaft. I collected it again on 23 January 2026.

Three or four days later, the exact same noise returned.

Back to the dealer it went.

After another lengthy period, I was informed BYD technical had become involved and the conclusion was that the measurement between the engine and engine mount was “out of tolerance”, requiring an adjustment to reposition the engine.

Eventually I received a call explaining that:
- an adjustment had been carried out
- a new engine mount had been ordered
- but the part was on back order with no ETA

I was then asked if I wanted to collect the vehicle while waiting for the replacement part.

At this stage I had already lost confidence in the car, so I asked what the expected timeframe was. The response I received was effectively: “There is no timeframe — it will arrive whenever the part becomes available.”

Weeks then passed with no progress.

Eventually, after discussions around rejection through the finance company, the dealership wanted the courtesy car returned and advised: “The adjustment has been carried out and we are confident the vehicle can be driven without the noise being present.”

I confirmed in writing that taking the vehicle back would not affect my rights should I later pursue rejection.

I then collected the car.

The very first left-hand turn I made, the exact same noise happened again.

I informed the dealer immediately and was essentially told: “The part is on back order — there is nothing further we can currently do.”

At that point I’d had enough.

In total, the dealership had my car for 41 days, repairs had already failed, the same fault persisted, and there was still no confirmed timeframe for resolution on a brand-new vehicle.

I escalated the matter through Santander Consumer Finance. An independent inspection was carried out and the complaint was upheld under the Consumer Rights Act due to failed repairs.

The vehicle has now been collected and the finance agreement unwound.

Overall, I’m massively disappointed — not just from a vehicle quality perspective, but from an aftersales/customer service perspective too.

I genuinely wanted to like the car because on paper it offers fantastic value for money, but my ownership experience ended up being the worst I’ve ever had with a new vehicle.

Hopefully this helps anyone researching the Seal U DM-i or dealing with similar issues.
