OT and speed transmitters

Hello, everybody.

I have recently also a hot start problem with my V8. It's the usual phenomenon: when it's cold, it starts without problems. If it's warm, it's just the starter, but it doesn't start. I know, I know, the subject has been discussed here many times, and it seems to be the OT donors in 95% of all cases. Now the said particle is not exactly cheap at the AUDI dealer (so ca. EUR 120 incl. ==References== So I checked with our local BOSCH service. He offered me the part for fair 58 EUR incl. Common. - No. It's not a BOSCH factory (I don't know if the original part is BOSCH). He also gave me the comparison number 077 905 381 (OT encoder) and 077 905 381 A (pin encoder).
Now my question: What do you think of these parts? Can I install it without hesitation (the connector type and the color also fit) or is the AUDI original spare part to be taken for safety?

For your help, I would like to thank you in advance.

MfG
