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.

ABS pump 5N0614109BA - how do you check it is the right part?
All you need to do is compare VAG number 5N0 614 109 BA from the label of your assembly with this unit - a genuine, used and working TRW hydraulic unit for Audi and Volkswagen cars. Here, a matching number counts for more than the car make itself.
TRW ABS unit 5N0614109BA for Audi and Volkswagen
The label of this unit shows several markings, but only one has a clearly defined meaning: 5N0 614 109 BA is the VAG catalogue number of the hydraulic unit, in other words the ABS pump. Next to it are TRW numbers 18808807, 54086625B and 18808707A - we reproduce them exactly as printed, without assigning them a specific function. The sticker also bears the texts ‘GN0’, ‘HW: H07’ and ‘SW: 0160’. When comparing with your own part, check all of these entries, not just the first one.
What is printed on the TRW label
- 5N0614109BA - VAG number of the ABS pump (hydraulic unit), on the label: 5N0 614 109 BA
- 18808807 - number from the TRW label, written as 18808807
- 54086625B - number from the TRW label, written as 54086625B
- 18808707A - number from the TRW label, written as 18808707A
The pump motor housing carries only a small white barcode sticker - it has no part number on it, so look for the listed numbers on the assembly label. We have ten other versions of this pump in the shop that differ in their suffix, so check the letters BA at the end just as carefully as the digits.
Signals that the ABS unit may be faulty
Damage to this type of assembly most often shows itself as follows:
- ABS stops working together with ESP/ASR,
- a valve fault stored in the control module memory,
- the ABS warning light coming on just after the engine is started.
Before ordering the part, connect a diagnostic tool, go through the stored codes and only then rule out simpler sources of trouble - a speed sensor at one of the wheels, a fuse, a chafed wire, a plug or battery voltage that is too low. Fitting is completed by bleeding the brakes; Volkswagen Group cars often also require the control module to be coded, and those with ESP a calibration of the steering angle sensor.
