W114 mercedes 280E efaw228 tester machine

 Hi jetronic family
Hi jetronic familyI am thinking of buying the test machine in the picture for my W114 280E vehicle. What kind of things will the machine be useful to me?  Or is it of no use?Thanks Kerim falay

Hi Kerim,

it is an adapter you can plug between ECU and wiring harness. And it is a multimeter where you can follow instructions how to measure sensors. It also gives a hint on trigger contacts and injectors - not in detail but you will have an idea. It is very expensive, consider 1000€ for it. Many need overhaul before you can use them. I have several of these.

+ Easy to connect on ECUs in bad locations in cars
+ Measures on ECU connector including wiring harness
+ Mercedes/Bosch instructions let you test all peripheral in step by step
+ Can start fuel pump and injectors for verification
+ Can give you an idea of trigger contacts and injector operation
+ Can verify coils on MAP sensor

- Cannot measure ECU or detuned MAP sensors
- Trigger contact verification limited
- Does not help with ignition or engine mechanical issues

Hi dr. Volker
It is price is 300 euro. I find it. It is good working. Seller said
What do you think? Must I buy?

Hi Kerim,
this is a very good price.

You can't loose money - buy it.

Regards
Norbert

Add: Don't forget to verify the seller. The price could be too hot...

Hi Kerim,

yes buy it if it is complete. But be prepared that devices that have not been used for a long time can cause some trouble with contacts. Go there with your car and connect it. Then you know.

Be aware that on kleinanzeigen.de many offers for EFAW 228 have been fake recently -> if you pay with paypal friends you could loose all your money. The picture from the original post was an example of a fraud attempt (pictures copied from web, in this case willhaben.at, where the real tester is offered for > 1000 € ).

So be careful before buying.
