P1890 on MINI
Transmission Adaptive Pressure Table Transfer
P1890 on MINI vehicles indicates transmission adaptive pressure table transfer. Au7o has documented this code across 1 MINI model — most commonly on Countryman. P1890 is a manufacturer-specific transmission code; on the applicable platform its official definition is 'Transmission Adaptive Pressure Table Transfer,' meaning the control module had a problem storing, transferring, or applying its learned adaptive shift-pressure values. Modern transmissions continuously 'learn' the line pressure needed for smooth shifts and store that data; this code sets when that adaptive learning data can't be properly transferred or is corrupted, often after a module replacement or programming event. On other makes P1890 can refer to different shift-control or CVT issues, so confirm against the specific vehicle. Symptoms typically include harsh, erratic, or poorly adapted shifting. Typical repair costs on MINI range from $300 to $2,500, depending on the specific model and root cause.
Common Causes of P1890
- •Transmission control module not relearned/reprogrammed after service
- •Corrupted or lost adaptive pressure learning data
- •Faulty or recently replaced TCM/PCM
- •Low system voltage interrupting module memory
- •Wiring or connector faults to the control module
- •Internal transmission wear preventing successful adaptation
- •Software calibration that needs updating

- ALL4 AWD System Coupling and Transfer Case Issues2011-2025
The Countryman ALL4 AWD system uses a Haldex-type electromagnetic coupling that can fail due to fluid degradation or pump motor failure. The transfer case can also develop leaks and bearing noise.
