This page collates alternative part numbers that owners have found to fit the TVR Cerbera (AJP V8 4.2/4.5 and Speed Six). Because TVR sourced many components from mainstream manufacturers, donor parts from Ford, Vauxhall, Rover, Land Rover, Saab, Jaguar, VW/Audi and others are often a cheaper and more available alternative to buying through a TVR specialist.
These are owner-reported fits drawn from years of Cerbera forum discussion. Always verify the part on the bench against the one you are replacing before fitting, and for anything safety-critical (brakes, fuel, steering, suspension) confirm dimensions, materials and ratings are equivalent to the original.

The correct Cerbera wiper motor is a Lucas 60027021A, a 29 W unit also fitted to the Jaguar XJ6/XJ12 — it bolts straight on, gearbox and all. The internal park switch is from a 14 W motor (Austin Mini / Land Rover Defender Series 2a/3, part 520160), which is why it is the weak point — it is running on a 29 W motor’s current. A Mk V Mini 14 W motor will work with its own gearbox but sweeps only 110° vs the Cerbera’s 170°.

Alarm fob (Meta / Abacus):
- Arm and disarm the alarm sixteen times, or until it stops responding — it is now in programming mode.
- Press the button on each new remote, then press the button on each original remote. Each action must be within 8 seconds of the last, or the alarm drops out of programming.
- Wait 8 seconds to exit learning mode.
- Test all remotes.
Immobiliser key (plinker):
- Insert the original plinker into the receiver hole.
- Switch ignition to ACC.
- Wait four seconds.
- Switch ignition off.
- Insert the new plinker and hold it in for two seconds.
The M36 immobiliser has five programming slots: two for the originally programmed keys, one for the optional alarm interface, leaving two free. Once those are full, the immobiliser must be reprogrammed by a specialist.
