Golf 5 2.0 TDI MED9.1 not let you read

[cawadany]

I have a problem with my car, a Golf 5 GTI 2.0 TFSI fitted with a MED9.1. I've always read and written safely, initially with powergate and then with mpps v5. A few days ago I connect mpps and I to read it: error "invalid key". Since the same mpps in the evening before I had blocked a edc16u31 (then recovery in recovery always with mpps), I think either the cable is defective and I buy a rooster v48. I plug in the cock, I start reading and.... error sk2, silentkey reading... it seems the same error of the mpps. At this point, I think that the problem is not the interface, but my ecu. What is pu? be successful according to you? C'? the way to resolve it? Of course I didn't trust to write......

with mpps put it in the reading, when you d? the error does not turn off the picture, but restart the mpps, after 2-3 attempts it should unlock and go read.
Also see if you can give a few tenths of a volt in + to the battery with a charger.

From how I understand the ecu when the law of an access key is not valid blocks access to a tot of time. In fact, the first time gave me the key is not valid, the subsequent times the required time has not expired. Then the last I see that it functions in this way, danny.

look up to you and behaves as if the keys you were expenditure in previous inputs for both reading and writing, if mpps is able to enter in recovery read? bypassing, I don't know to explain why? but ? gi? success

Unfortunately mpps for now I don't. But how do you activate this recovery?

there it goes only after the smanetti 2-3 times that you d? the error without shutdown the framework restarts, mpps, and then switch off the panels off and back on without restarting mpps but retrying the read-after-error. 2-3 times that I do so? go into recovery and law and I unlock well as the reading.

I did not know, otherwise I would have tried when I was mpps. I should see if c'? way to do it with the cock....

write it down in the bdm if you can't by obd, at least you have a backup copy

[cawadany]

Do you think it is worth the try to read it at the counter? Then, by connecting to the output pin?

do the test that you said danny does not harm, but according to me, get a jig bdm with a e xxx bosch, open the email and read it from the pitches inside with cock v48 you can find the guide between the documents of your gslletto, under the heading bdm later med9.1
