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.

How an alternator works
An alternator works in harsh conditions: high temperature, moisture and vibration. Parts that wear include the bearings, brushes and electronic components. Replacing the alternator usually means removing the drive belt, so check its condition at the same time.
How to recognise a faulty alternator
- the engine stalls under heavy electrical load,
- the radiator fan runs slower than usual,
- there is a whistle from the belt area,
- the battery is constantly flat.
If the battery is very worn, have it tested together with the alternator, as a weak battery puts extra load on the charging system.
Fitment
Compare the full number 0 124 425 048 with the number on your alternator. Different versions were fitted to the same models, so the number decides, not the model alone. Versions differ in current output and mounting, among other things, so even similar numbers do not always mean the same alternator.
