A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

Used BMW MINI ABS pump with number 9813345
This is a used original ABS pump with a control unit for BMW MINI cars: an aluminium hydraulic block with valves and a pump motor, with the electronics bolted to it. The main number is 9813345, and the other numbers from the labels are listed below. According to the listing, the pump comes from the BMW MINI model.
Part number 9813345 and related numbers
The numbers from the listing, as written on the labels and as a single string:
- 9813345, BMW number in short form, without the group prefix,
- 9813347, BMW number in short form, without the group prefix.
The full numbers matter, including their endings. If in doubt, send us a photo of your pump.
What ABS problems can point to
- the brake pedal pulses or feels uneven for no obvious reason,
- the ABS activates for no reason during normal braking,
- brake fluid leaks from the hydraulic block, which requires immediate action,
- on a slippery surface the wheels lock up noticeably sooner than they used to.
ABS faults should not be ignored, because without anti-lock protection the car brakes less well on wet or slippery roads. Diagnosis and fitting are best left to a garage with a suitable scanner.
