Possibly. Webasto Do the ThermoTop in two main flavours - plain and ThermoTop C. Have deleted OP so no idea which one was mentioned before.
The plain one takes it's fuel feed from the engine's injector return pipe and stores about 30 minutes worth in an internal tank. This requires a low(ish) return pressure - fine for the old 110/90 Diesel Turbo, and 200TDi, but not for the Td5 which has a very high pressure system. Don't know about 300TDi or the TD4 I'm afraid.
For the TD5 I needed the newer ThermoTop C version - it gets it's fuel independently by having it's own pickup in the tank. Because it pumps it's own it can run for much longer - standard timer control allows two one hour burns instead of a single 30 minute one. On my current car (VW Caravelle, sorry) it even has it's own battery and can run until the battery dies or tank runs out).
