Xtool V401 Using Tips
Prime Fuel Pump after changing TDI fuel filter:
Diagnose > Common System > 01 Engine > 04 Basic Settings > 035 : Pump runs for 30 Seconds.
TRANSMISSION - Reset DSG Adaptives:

Transmission Tolerances (Engaged Calibration):
@ Operating Temp > Park > ER/Hand Brake On > Key On > Diagnose > Common System > 02 Transmission > 04 Basic Settings:
061 > Wait for any numbers to stop changing > Start Car > You'll soon feel the gears cycle, wait for all #s to stop changing > ENTER > Engine Off
(8/30/15) Mine settled at 141, 128, 4, 1

Transmission Tolerances (Synch. Point. Measurement)
@ Operating Temp > Park > ER/Hand Brake On > Key On > Diagnose > Common System > 02 Transmission > 04 Basic Settings:
060 > Key On > Wait for any numbers to stop changing > Start Car > You'll soon feel the gears cycle, wait for all #s to stop changing > ENTER
(8/30/15) Mine settled at 13, 0, 4, 1
DONE, release hand brake, turn car off or drive.

065 (Clutch pressure), all showed 0.00 PSI running or not, so do not know if/how reset.
062/067 - Clutch Adaptation, those numbers did not change. 062 is if Control Module Version is => 0800, else 067.
068 - Clutch Saftey Function, those numbers did not change either.
063 -Reset Values (Steering Wheel Paddle Installation); did not use.
069 -Reset Values (ESP & Tip Cruise Control Installation); did not use.

Windows down via Keyfob adaptation:
Diagnose > Common System > 09 – Central Electronics > Adaptation > 006 > Change 0 to 1 > ENTER
Disclaimer: May be an issue where it sometimes won't let you navigate to Channel 006. It seemed like this issue was prevalent if I you have been
fiddling around in other function areas. However, if you navigate straight to Central Electronics / Adaptation from plug-in, this should work.

XTOOL V401 Reviews:

I received my Xtool VAG401 scanner recently around £36.00with DHL shipment to my place.For anyone else thinking about buying this reader, they're a lot cheaper direct from Xtool.UK company, free postage to UK/IRE
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 microSD card reader used for the updates. 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 came with a 160 * 160 LCD screen, and therefore no need to use a laptop or computer when diagnosing.
The OBDII cable that hooks between the VAG401 scan tool 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. This is on my Passat TDI.
It reads error codes just like VCDS, although there is no auto scan function to scan all modules that I can find. It has successfully found all installed features on both my Passat and my friends Allroad. Both of my cars are dual knot 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 module menus 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, etc. It can code modules, do adaptations, etc.
I figured out to update mine. Download the update application from the Xtools website, and use the 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 great. It has a lot of capability for the money and is very convenient. However, user support is nonexistent, so being previously familiar with VCDS is a definite plus. I can not speak for how well it works on current model cars.

Customers' feedback:
1. Hi, have V401, trying to reset Golf mk6 2010 airbag. Airbag reads as VW10. In th erest page no VW10 appears , VW3, VW5, VW6 but no VW10. Am I doint something wrong? thnaks

Solved: Hi, Thanks for coming back to me. I managed to sort out the problem. The communication between car and unit takes a long time, so long that I had assumed it had frozen. However now I have been a bit more patient it presented me with the expected fault codes and then allowed me to reset.
So ultimately this is down to user error / impatient.
One improvement you could do is mention in your documentation that the communication time can vary between the different parts of the car its communicating with.
Apart from that all good.
First pic is the scan showing the airbag as VW10

Second and third pic are the fault codes.

XTool V401 V-A-G OBD Scanner FAQ 
 Product/Customer Support

Q: Are there any XTool FAQs, Wiki pages or Forums?
A: User Manual only. No additional product support, Wiki, Forum or FAQs on the company's web site. There are various tutorials and reviews available on Youtube and other VAG Forums.

Software Update
Q: Is it easy to access and does it update frequently?
A: Updates are done through the company's web site. Last software updates Rev (7.1) from 2013
VAG software specific and not a generic OBD reader. Users should be aware of the "Failure to connect" message which has been attributed to vehicles with aftermarket head units. Looking through Amazon customer comments, the device is also reported to be "a bit slow" in connecting and running fault scans but that could be attributed to the vehicles given this can be used on vehicles as old at 1996.

Capabilities & Limitations (What can it do or not do?)
Q: User Interface - is it intuitive or is there a steep learning curve?
A: No factory supports beyond the user manual. Users report they have to search Google or YouTube in order to do anything beyond the scope of the User Manual.

Q: Data Export - Can you save or export the results as a txt file or other format?
A: Data can be saved but is only exportable in Chinese, so exports are basically unusable. Therefore the results of an Auto Scan cannot be exported as a text file.

Q: Can it clear faults?
A: Yes. Auto scan and fault clearing are possible.

Q: Adaptations & Basic Settings - Can it perform these functions?
A: Yes. But it's not known to what extent Adaptations are possible. (e.g. Unknown if the Roadster Roof Adaptation is available.)

Q: Service Reset - Can you do a service reset? (e.g. reset period for next oil change)
A: Yes.

Q: Output Tests - Can it perform them? (e.g. cooling fan, fuel pump, etc.)
A: Yes.

Q: Measuring Block Data - Can you see single or multiple data blocks?
A: Yes. But you will need to know which blocks you want to view.

Q: Live Data - Can it create and/or output live charts or graphs?
A: No. It only displays with pure numbers.

Q: Long Code changes - Does it support changing the long codes and how easy is it to do?
A: Can be done but not an easy task given there's no factory information on how to do it.

Q: Vehicles Supported - how many vehicles can you use this on?
A: Unlimited number of vehicles.

Q: Additional Costs - any sort of "pay as you go" or recurring charges/subscription fees?
A: There are no additional costs after the initial purchase.

Q: Others
1.) Is it possible to export an Auto Scan as a text file using the SD card and then upload it to a PC?
2.) Is it VAG software specific like VCDS and OBDeleven or just a generic OBD reader?
A: 1).The XTool is VAG specific.
There is no way to export data directly from the tool itself. When I have the chance I will examine the file structure on the MicroSD card and provide an update with what I find.
2).The VAG401 is not a cheap alternative to VCDS but instead an addition to VCDS that can be kept in the vehicle. Supposedly it can do everything VCDS can do. But V401 xtool is better to do simple jobs over VCDS, such as check for errors, reset an accidental airbag trip or service reminder in less time than it takes to boot up VCDS, but if you plan on a lot of custom tweaks & adaptations you'll likely be frustrated.
