XTOOL VAG401 Customet Feedback

 I’ll chip in some words of XTOOL V-A-G401 scanner.

XTOOL VAG401 OBD Diagnostic Tool bought ,I received my Xtool VAG401 Handhold diagnostic tool recently around $45 with free shipment to my place. Tried it out straightly on my 2005 Passat and found it quite easy to use. If you have used VCDS VAG COM cable, you can probably figure out how to use this without reading the manual!


They include a reader. They also include a USB cable. The only use I have seen for the cable is to power up the unit from a USB port instead of your car. It is hand-held diagnostic tool with 160*160 LCD screen and no need to use a laptop or computer when diagnosing.

Turn to Auto Diagnosis

The OBDII 16PIN cable that hooks between the XTOOL VAG401 OBDII and the car is a straight thru cable. There are no components in the back shell of the OBDII connector. The other end has a 15 pin male d-sub connector.

I was able to use mine to read out the key code from the dash. I verified that it was the same as one I had gotten previously from VAG-Tacho. It reads error codes just like VCDS, although there is no autoscan function to scan all modules that I can find. It has successfully found all installed features on both my Passat and my friend’s Audi Allroad. Both of cars are dual k not CANbus. I have not tried it on CANbus car yet.

The best way I can describe the interface to the modules is the older VCDS lite interface. The original modulemenus were almost a copy of VCDS, although the latest update simplified them somewhat.

It supposedly can match keys to the dash / immobilizer, although I have not tried it. It has a few other functions that VCDS does not have, such as mileage changes, oil reset, SRS reset etc. It can code modules, do adaptations, etc.

I figured out to update mine. Download the update application from the xtool website, and use the Xtool VAG401 serial number as the user name, and the password from the about screen as the password. You do not need to register. I downloaded the updates, and it said the update was successful. When I started the diagnosis, it loaded a new .bin file. Menus changed somewhat, and new options were added.

I got it in a couple of days. If you travel a lot, you can keep it in the car. You do not need a computer or power supply to use it, which is convenient. I can’t speak for how well it works on other cars but works fine on my 2005 Passat.





Miocropod 2 clone - won the lottery

I won the lottery!

I bought my miocropod 2 clone from, same as what Radius bought. It came with a hard drive that is barely working. Its making beeping sounds and clicking and on its very last legs. I was able to make a backup though and there is actually a second partition on it with an Acronis backup image already created from 8/15/17. Anyway I will have to contact the seller and arrange for some discount since the hard drive is virtually useless.

Anyway, the main thing is that the miocropod 2 had the required circuits etc, and the DRB3 works after following most of Radius’s instructions. I had to change it up since I did follow his instructions exactly, but the flexnet update didn’t work, and so it failed and the drb3 did not work.

In order to get it to work, I had to change the date. In the beginning when installing the stubs, his directions had already instructed you to change the date to 1/1/17, then navigate to the folder and install the three stubs. Reboot. Try to use flexnet connect to update but it failed. Windows update also errored because of the wrong date. So I changed the date to the correct date. Now flexnet connect worked and I was able to update K-line and enhanced drb3. As soon as both had updated, I disconnected internet and then changed date back to 1/1/17. Then I followed the rest of the instructions. Plugged in the pod, waited for windows to see it and make the virtual network, and then launched wiTech. Launched enhanced drb3. Success!! It works!!

So the instructions are good, but at least for me, I had to fix the date to the correct date to get the flexnet updates. Once updated, disconnect the internet and change the date back to 1/1/17 for it to work.


Radius’s instructions: the thread from


The device I purchased is an OFFLINE ONLY version of micropod 2, but I only use it for diagnostics, not for programming as I do not have a TechAuthority account. So if you need one for online use this is not the unit to buy.

These are the steps I followed to get Enhanced DRB III Emulator to work:

1: Make a backup copy of the partition from the hard drive included with the micropod!

2: Install HDD in laptop

3: Set date to 01/01/17 BEFORE booting from laptop

4: Boot to HDD

5: Allow windows to install drivers, etc, as needed for your laptop and reboot as needed.

6: Once all of that is done, do NOT run WiTech yet!

7: Turn OFF internet!

8: Navigate to C:ProgramDatawiTECHjserverdatacorestubs

9: Install DRB Emulator stub

10: Install DRB Enhanced emulator stub

11: Install K-Line stub

12: Reboot computer

13: Set date back to current date

14: ALLOW internet access

15: Run Flexnet software updater. Do NOT update WiTech!!!

16: Flexnet will find updates for enhanced DRB and K-Line

17: Install K-Line update first

18: Install Enhanced update next.

19: Turn date back to 01/01/17!

20: Once updates and downloaded and installed, turn OFF internet and NEVER turn on again!

21: Reboot computer

22: Attach Micropod to car. When green LED turns on, turn on car ignition

23: Attach USB cable to PC and Micropod

24: When Windows is done installing drivers, etc, you should show a network connection in the tool tray with no internet access

25: Run Wi-Tech

26: Press “Launch DRB III” button in lower right hand corner

27: Accept EULA

28: DRB Emulator will launch.

29: Enjoy.



I already tested it on a 2010 Charger under witech and works flawlessly, and got a 2004 Dodge pickup and under the emulator worked perfectly. I already called my locksmith, who drives an 04 Sprinter to try it as well.




How to raise and lower idle rmp using a Tech II scanner

Confirmed! Tech II scanner is able to raise and lower the idle!


It’s possible for GM vehicles to get the ecm reprogrammed for the fast idle increase. your local dealer should be able to help you out. here is how it works.



Programming ECM For PTO Idle Up Operation



2001-2007 Chevrolet Silverado Classic

2003-2009 Chevrolet Kodiak

2001-2007 GMC Sierra Classic

2003-2009 GMC TopKick

with 6.6L or 8.1L Engine




Connect the Tech 2 and follow the steps below to program the ECM for idle up feature with PTO operation:


Turn on tech 2 and build the vehicle


select “Powertrain” (Or “Vehicle Control Systems” on later models)


select “Special Functions” (or “Module Setup” on later models)


select “PTO Options”


select “Change Options” (soft key at bottom of the screen)


select F1 “PTO Preset Speed Control”


select pto max engine speed set to 2200 – 4400 rpm (not below 2200)



Note: These steps will not allow the engine rpm to exceed the rpm setting, even during normal driving if the PTO switch is on


select stand by speed (base fast idle ) set to 1200 (this setting is initial fast idle)


select PTO set speed – set to 1400 rpm


select PTO resume speed – set 1700 rpm


select PTO max engage speed – set to 1800 rpm (PTO engagement inhibit speed)


select PTO engine shutdown – no


select PTO engage relay – no


select PTO feed back -no


select “Reprogram” (soft key at bottom of screen) “Waiting For Data” displays on screen-once data comes back verify settings remain


key off- until tech 2 “beeps” and screen shows “no communication” (Very important step if missed setting will not store)


key on – verify settings remain on list
