Autel AP200/AP200M Review on Mercedes 38-PIN W163 W210 etc

Autel AP200M BT dongle is the most affordable and portable scanner. Good coverage, very good shareable reports in PDF format. Included in price EOBD and one car line.

MaxiAp200 app software installation simple and easy. Very large download. Uses 3.65 GB of internal storage.

HT200 is the same as AP200. But it will not support 38 pin adapter to scan Mercedes-Benz W210s. It will only do an EOBD to limited access ECU only.

Users have tried AP200M on W163, W164, W166, X166 and W210. Works like a champ. AP200M (red dongle) can support all these, so as AP200 (the white dongle).

Autel AP200 is better because it has lifetime support for a single make (no yearly fees at all for the first brand). Additional brands will cost $21.99 per year. AP200M only one year subscription for a single brand, 19.99$ later.   The advantage is with the AP200 you get lifetime full support for the first vehicle, rather than one year with AP200M.

The 38-pin adapter is available on

Here’s the prove that it can be used with Benz 38-pin adapter.

Live data was obtained through 16 pin OBDII. After selecting vehicle there was a choice of 16 or 38 pin. That’s what prompt you to take it for a spin with 38 pin adapter.

AC performance evaluation. It is close to dangerous heat around here. Vehicle parked outside will reach 50C + within 30 minutes.

Readings taken few minutes apart. Ignore diagnostic time in files. File name reflects actual time and date.

you can also use it to read and reset transmission faults.


2nd test goes to a Mercedes W210 MY2000 production date 10/99

It does not auto detect VIN on this car. Even MB Star diagnostic system will not auto detect it. Once you select it manually VIN pops up. Same with Autologic. Same with my ’99 ML320.

But it cannot read ETC and AAC data. Pretty much anything that requires HHT-WIN is out. Autologic or SDS are only scanners that work.

AP200M has no capability of actuation of valves neither. (does not support bi-directional ops).



MaxiAp AP200 works just fine on entire W163 and W210 line. It would be great to have non-expiring Benz subscription with AP200 that works with 38-pin adapter.

It does have some bidirectional capability like forced DPF regeneration or Electric Parking Brake open/close for service. Limitations are software only as the dongle itself is very fast and capable.

Hardware has bidirectional capability limitations are in software.
I have used it to move rear calipers with electric parking brake to assembly position.

It works just fine with same limitations as other Autel products. Anything that requires HHT-WIN like EGS live data is out.

For full set of diagnostic functions you need SDS clone or Autel MP808.
