It's probably the only thing I miss on my DS (well, that and the spare wheel...) Ex AA Series III LWB Safari - Gone
300TDi Disco (bought new - terrible car) sent back after 18 months
Freelander 1 Estate - leased, given back at end of lease
200TDi Disco (bought from a mate with 100,000 on the clock) - Gone
Disco 2 TD5 - sold and exported to France
FR2 TD4 GS - Gone
FR2 SD4 HSE - Now changed for a DS
New model ex-demo Evoque S 180 in white
Unable to order a new DS, so gave up. Now have a Volvo S90 Recharge.

Mine are set at the "warmer" range and react like "Taz" explains, hot after about a minute and by a couple minutes......

Because nobody posted a response to the original question, below are the variants.
On my car, for example, by factory, is set option 4: 31 - 37.
I believe it depends on the market and can be changed by modifying the CCF...

1. LOW:28, HIGH:35
2. LOW:30, HIGH:36
3. LOW:30, HIGH:37
4. LOW:31, HIGH:37
5. LOW:31, HIGH:38
6. LOW:32, HIGH:38
7. LOW:33, HIGH:39
8. LOW:34, HIGH:40
9. LOW:35, HIGH:41
10. LOW:36, HIGH:43
11. LOW:40, HIGH:46
