J’ai pas compris ### 1/5 — Garbage *2024-08-05* Downloaded app to diagnose BMW vehicle. It didn’t let me log in with an Autel account that I had to create. Makes me wonder if this is a scam, or you actually need a paid subscription, and it’s not free ### 1/5 — Bmw mini : Adaptation et calibrage *2023-12-10* Adaptation Moteur inexistant - calibrage VtG inexistant - adaptation Boîte vitesse inexistante . Beaucoup option d’entretien inexistante …Moteur adaptation … Calibrage VTG … Adaptation BVA ….mise à jour en urgence ingénieur 😒 ### 2/5 — won’t let me connect *2023-04-08* tells me to connect to the obd reader even when i’m connected and gives me no other options ### 3/5 — Good product however very buggy *2021-12-22* A week ago I used this to rad the errors on my 2010 535 xi BMW and flashed new codes doing the injectors. Today 12-22-2021 I updated to new version and now when I go to the screen to flash the new injector code the app crashes. I hope they don’t take 5 months to push out another version. ### 1/5 — Autel *2020-08-16* Kein Deutsch!!! ### 3/5 — Not working *2020-07-11* Opens and clothes in seconds. Don’t waist your money buying Autel products. Big scammers! ### 1/5 — Email scavenging app!! *2020-05-13* I won’t let you do anything without your email, once you register it won’t work. My Bluetooth ODB reader works just fine with BimmerCode and other apps but this one claims it doesn’t see it. Avoid!! ### 5/5 — App works *2020-03-09* This app worked for my 2005 bmw 325i. I was able to read ABS error codes and clear them. Works beside the other app which is called “HT200” and “MaxiApp200” which allowed me to reset my steering angle for error code BMW ETC 5E40. I’m in love with this app. Keep up the great work. ### 2/5 — Apps broke *2020-01-12* After the update the app is blank and broke ## Frequently asked questions about Diag ### What is Diag-BMW used for?
