Xhorse Dolphin II Error Code 70 Solution

Problem:

Xhorse Dolphin XP005L keeps showing error code 70 and the battery pack is in BIOS mode. The battery won’t charge. How can I resolve this?

Solution:

1. Connect the Dolphin XP005L to power.

2. Connect it to the phone using the Xhorse app.

3. Enter Update/Upgrade and update firmware and database completely.

4. Use a stable Internet connection; If it fails, try the phone’s hotspot.

5. If the phone does not allow you to complete the update, do it from a computer using the Xhorse Upgrade Kit. There is documentation for this same Error 70 that specifically recommends switching to the Upgrade Kit when the mobile update fails.

User feedback:

UPDATE!!

It’s already solved.

Here’s what worked for me.

You remove the cover where the battery goes and disconnect that green connector.

1.Set your machine and turn it on with the charger connected (and the green connector disconnected)

2. update the firmware (the update should take around 11 minutes)

3. You connect the green connector and update the machine again

4. You turn on the machine and in theory your machine should be fine.

Xhorse Audi BCM2 Adapter V2 Review

I’ve used the Xhorse BCM2 Encrypted Solder-Free Adapter on several BCM2 jobs. It’s a practical bench setup for encrypted BCM2 read/write work on Volkswagen, Audi, Porsche, and Lamborghini, and it works with both Multi-PROG and VVDI Key Tool Plus.

Who Should Buy It?

Good fit for:

• Technicians regularly working on VAG BCM2 modules.
• Locksmiths who need BCM2 bench read/write capability.
• Workshops that prefer solder-free connections.

Not the best fit for:

• Shops that only see BCM2 occasionally.
• Beginners with no BCM2 bench experience.
• Technicians who don’t need BCM2 read/write work.

Real Workshop Notes

The Connection

The connection is pretty simple once you have the right BCM2 version. The adapter locks onto the required points and stays in place well.

The kit has two adapter boards and two cables for different BCM2 versions. I like the setup because there’s no soldering involved.

Reading

I usually do a Read ID first. If the CPU is recognized correctly, I move on to D Flash and P Flash.

D Flash is relatively quick. P Flash takes longer, but the actual reading process was stable in my testing.

One Thing to Expect

The BCM2 needs to be unlocked again for each operation. It doesn’t stay unlocked after the first decryption.

That adds some time, especially if you’re doing several operations. I wouldn’t permanently unlock it just for convenience because that means erasing the data.

Overall

Once the correct adapter and protocol are selected, the workflow is straightforward. Writing follows basically the same approach as reading.

What I Liked

1. Stable fit: The adapter stays firmly on the BCM2 connection points.
2. Solder-free: No direct soldering to the board.
3. Two setups: Covers different BCM2 versions.
4. Read ID: Useful for checking the connection before a full read.
5. MultiPROG&Key Tool Plus: Good flexibility if you already use either platform.

What Could Be Better

1. Repeated unlocking: Adds extra time between operations.
2. P Flash speed: Larger data takes noticeably longer to read.
3. Correct identification is important: The BCM2 version, CPU, and protocol all need to match.
4. Some bench experience helps: It’s not completely plug-and-play for someone new to BCM2 work.

Would I Buy It Again?

Yes. After using it on multiple BCM2 jobs, I’m comfortable keeping it in the bench setup. The BCM2Solder-Free Adapteris stable, solder-free, and easy to work with once the correct configuration is identified. The repeated unlock step is the main thing to account for, but it hasn’t been enough to put me off using it.

How to Add 2025 Chevrolet Aveo Key with VVDI Key Tool MIDI

For this 2025 Chevrolet Aveo, we used the Xhorse VVDI Key Tool MIDI to add a duplicate key. No code is needed on this model—the key can be matched directly through the IMMO menu.

Key Programming

1. Go to Immo Programming >> SAIC-GM-Wuling >> Immo System >> Xingchen >> Key Count. The current key count is 2.
2. Select Key Programming, insert the new key to be matched, and turn on the ignition.
3. The VVDI Key Tool MIDI programs the key in less than a minute. The screen shows “The current key programmed successfully” followed by “Matching completed.” Up to 4 keys can be matched.
4. Turn off the ignition and wait for more than 30 seconds.

Verification

Turn the ignition back on and check the new key. The remote control works, and the engine starts normally. The duplicate key is ready to use.

VVDI Key Tool Plus Cannot Auto Diagnose VAG System Solution

Doing a spare key on this VW Caddy using the Xhorse VVDI key tool plus. When we try to automatically diagnose the model it won’t actually detect what system it is.

It says unable to automatically diagnose and it gives us a few options on the side to try.

VAG systems when auto diagnose doesn’t work – Do this.

We go to Select by type and then we come down and select 4th Immobilizer system that it showed you on the last screen.

It tells us to try a 24C64. Let’s try this.
Let’s try reading the eeprom. If it does not working, we will go back and try other options.
Dashboard is off; failed to read data.

Let’s go back and select other options.
Go back and setect 24C64 2013 onwards.

Try reading eeprom.

Dashboard goes dark.
Original key is in the ignition.
When you see this means that we have the correct dashboard and we can start to read the eeprom.

Geely Coolray 2024 Change KM with Xhorse Multi Prog

It’s a Geely Coolray 2024. The owner needed to slightly adjust the mileage to maintain the dealership’s warranty (they had adjusted it before the maintenance).

The panel looks like this.

First, remove the instrument panel. To do this, pull the visor up with one sharp movement, unscrew the 12 screws, and then remove the panel. The rear panel cover is secured with clips and 4 screws.

EEPROM chip which contains the mileage.

He read the m24c08 microcircuit using Xhorse Multi prog programmer, but it’s necessary to desolder it; you can make a mess with a clothespin.

Let’s remove the dash panel, lower the fuse box, and unscrew the four BCM mounting bolts. It’s on the left pillar at the top of the front; it contains a bunch of components. Removing it is very inconvenient. Next, we need to find something to read it with. There’s no EEPROM there; all the information is stored in the processor. The MultiProg programmer from Xhorse helped us with this. The connection is easy, but you’ll need to be handy with a soldering iron.

He read it, sent it to the same programmer, uploaded it back to the BCM, and then re-entered it into the instrument cluster.
He put it back together, and bingo! The mileage is exactly what he needed. He ran the auto launcher through the modules, and the transmission included the mileage from the BCM.
