This has been an issue with this app going on 2 years. A shame -- Mardis Gras, 2025-04-22 ### *---- "Works on Android" All the features of this app work on my friends Android but not on my iPhone, it has hard or impossible to use most if not all features. All I can do is look at the trouble codes. -- WildBoyJake18, 2024-10-26 ### *---- "Limited use application when it works" App doesn’t consistently see connected Bluetooth devise. Limited options for diagnostic. Can’t activate or remotely control engine components for testing -- paw9090, 2024-08-02 ### *---- "Bluetooth tool will not stay connected" Everytime you open this app it disconnects the Bluetooth from mobile device to diagnostic tool. $500 for the tool and not useful at all. -- Gymtunes, 2023-02-27 ### ***** "Great for troubleshooting EFI" I have been using this for a bit on my iPhone and it works great for troubleshooting and repairing efi’s engines. The dashboard for sensors gives everything I need in one simple display. No more bulky laptops bungee corded to the tractor. -- poncho deloggo, 2018-12-28 [View all Kohler Diagnostic System reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Kohler Diagnostic System Discovered Keywords - kohler diagnostic system ## Kohler Diagnostic System Available In - [United States](https://apptail.io/app/kohler-diagnostic-system-eFCd/united-states) - [Armenia](https://apptail.io/app/kohler-diagnostic-system-eFCd/armenia) - [Austria](https://apptail.io/app/kohler-diagnostic-system-eFCd/austria) - [Australia](https://apptail.io/app/kohler-diagnostic-system-eFCd/australia) - [Barbados](https://apptail.io/app/kohler-diagnostic-system-eFCd/barbados) - [Belgium](https://apptail.io/app/kohler-diagnostic-system-eFCd/belgium) - [Bermuda](https://apptail.io/app/kohler-diagnostic-system-eFCd/bermuda) - [Brazil](https://apptail.io/app/kohler-diagnostic-system-eFCd/brazil) - [Belarus](https://apptail.io/app/kohler-diagnostic-system-eFCd/belarus) - [Belize](https://apptail.io/app/kohler-diagnostic-system-eFCd/belize) - [Canada](https://apptail.io/app/kohler-diagnostic-system-eFCd/canada) - [Switzerland](https://apptail.io/app/kohler-diagnostic-system-eFCd/switzerland) - [Chile](https://apptail.io/app/kohler-diagnostic-system-eFCd/chile) - [China](https://apptail.io/app/kohler-diagnostic-system-eFCd/china) - [Colombia](https://apptail.io/app/kohler-diagnostic-system-eFCd/colombia) - [Cyprus](https://apptail.io/app/kohler-diagnostic-system-eFCd/cyprus) - [Czechia](https://apptail.io/app/kohler-diagnostic-system-eFCd/czechia) - [Germany](https://apptail.io/app/kohler-diagnostic-system-eFCd/germany) - [Dominican Republic](https://apptail.io/app/kohler-diagnostic-system-eFCd/dominican-republic) - [Algeria](https://apptail.io/app/kohler-diagnostic-system-eFCd/algeria) - [Ecuador](https://apptail.io/app/kohler-diagnostic-system-eFCd/ecuador) - [Spain](https://apptail.io/app/kohler-diagnostic-system-eFCd/spain) - [Finland](https://apptail.io/app/kohler-diagnostic-system-eFCd/finland) - [France](https://apptail.io/app/kohler-diagnostic-system-eFCd/france) - [United Kingdom](https://apptail.io/app/kohler-diagnostic-system-eFCd/united-kingdom) - [Greece](https://apptail.io/app/kohler-diagnostic-system-eFCd/greece) - [Hungary](https://apptail.io/app/kohler-diagnostic-system-eFCd/hungary) - [Indonesia](https://apptail.io/app/kohler-diagnostic-system-eFCd/indonesia) - [India](https://apptail.io/app/kohler-diagnostic-system-eFCd/india) - [Italy](https://apptail.io/app/kohler-diagnostic-system-eFCd/italy) - [Japan](https://apptail.io/app/kohler-diagnostic-system-eFCd/japan) - [Lebanon](https://apptail.io/app/kohler-diagnostic-system-eFCd/lebanon) - [Lithuania](https://apptail.io/app/kohler-diagnostic-system-eFCd/lithuania) - [Malta](https://apptail.io/app/kohler-diagnostic-system-eFCd/malta) - [Mexico](https://apptail.io/app/kohler-diagnostic-system-eFCd/mexico) - [Malaysia](https://apptail.io/app/kohler-diagnostic-system-eFCd/malaysia) - [Namibia](https://apptail.io/app/kohler-diagnostic-system-eFCd/namibia) - [Netherlands](https://apptail.io/app/kohler-diagnostic-system-eFCd/netherlands) - [Norway](https://apptail.io/app/kohler-diagnostic-system-eFCd/norway) - [Pakistan](https://apptail.io/app/kohler-diagnostic-system-eFCd/pakistan) - [Saudi Arabia](https://apptail.io/app/kohler-diagnostic-system-eFCd/saudi-arabia) - [Sweden](https://apptail.io/app/kohler-diagnostic-system-eFCd/sweden) - [Singapore](https://apptail.io/app/kohler-diagnostic-system-eFCd/singapore) - [Suriname](https://apptail.io/app/kohler-diagnostic-system-eFCd/suriname) - [Thailand](https://apptail.io/app/kohler-diagnostic-system-eFCd/thailand) - [Türkiye](https://apptail.io/app/kohler-diagnostic-system-eFCd/turkey) - [Ukraine](https://apptail.io/app/kohler-diagnostic-system-eFCd/ukraine) - [United Arab Emirates](https://apptail.io/app/kohler-diagnostic-system-eFCd/united-arab-emirates) - [Vietnam](https://apptail.io/app/kohler-diagnostic-system-eFCd/vietnam) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
