User-friendly PASSAT 2.0 scanner for my grandpa

Picking up an inexpensive but powerful OBD2 scanner for his 2005 VW PASSAT 2.0 makes my 80-year-old grandfatehr Jack giddy. The oil service light in his PASSAT came on a few days ago, and he wanted to solve it himeself.

Engine problems are often due to a bad fuel mix, lack of compression or lack of spark. There will be fault codes once the check engine light illuminates and lasts for hours. The check engine light will go out only when the codes are cleared, and before clearing the codes, you will have to find them. Therefore, my grandfather, follwed the online advices and decided to buy a OBD2 scanner to fix the problem on his own.
OBD2 code readers for vehicles such as PASSAT are usually expensive, though they are very powerful as well. But Jack was trying to look for a cheap one which only has to be able to get him the error codes. After learning this, I bought him an iOBD2 scanner for VW, a code scanner that supports diagnoses through Android phone by Bluetooth but only costs less than $100.
Jack received the package from China yesterday, and connected it to his PASSAT 2.0 immediately. Then he told me last night that the iOBD2 VW was great, smart and very easy to use. Even though he only had a little knowledge about car diagnosing, he cleared the error codes with the device for less than 5 minutes, including the time he wirelessly connected the tool to his Android.


Convenient and safe ak90 for BMW EWS key programming

BMW key matching should take BMW IMMO systems into consideration, including EWS, CAS1-CAS3+, CAS4 (CAS4+). In my opinion, BMW AK90 is convenient and safe for BMW EWS, BMW OBD is practical and convenient for cas1-cas3+ and cas4 maybe YANHUA master, more stable. Here let me focus on ak90.

First of all, ak90 key programmer is for BMW EWS system, all ews key information from 1995 to 2005, available with EWS2.1/EWS2.2/EWS3/EWS3.3/EWS4/EWS4.4 now.

Second, it can do for BWM CAS, too, but mainly for EWS system.

Thirdly, its version is now v3.19, working with xp (although xp computer operating system users has not technique supported from Micro, many company has released supported function for xp system, can use xp safe)

Fourthly, for ak90 is with two languages available, English and Chinese, you could select your languages as you install, as picture below:


Finally, when programming BMW new keys with sk900, it is not need to remove chip.

Ak90 key programmer is safe and effective for BMW EWS key programming!

A tool to reset 2006 Mercedes S430 airbag light

Hi, Lene,
I have a 2006 Mercedes S430. The cars airbag light came on without any sign last night. I am thinking about turning off the airbag light myself. Can you recommend a cost-effective tool? Thank you very much.

Dear Wright,
There are three Mercedes diagnsotic tools that can reset 06 Mercedes S430 airbag light. They are : MB Star C3, MB Star C4 and MB SD Compact C4. For DIY-ers I would recommend you to buy MB Star C3. The tool is much cheaper than the other ones. And its functions is actually enough for amateur repairmen.
The obd2 tool can not only read and erase airbag light fault code, but also clear light for other systems like ENGINE, AUTO-SPEED, AIRCONDITIONAL SYSTEM, SRS, ASR, MPL, GM, BENZ ORIGINAL ANTI-THEFT, DASX SYSTEM, KEYZESS GO SYSTEM and OBD-II SYSTEM. Hope this is helpful.
