I agree on the conclusion that 0.0 or P means that something is very wrong inside the tacho.
I would like to try to find a cure for this, and would be interested in getting such a failed tachometer for close inspection and possible repair. If anyone have one lying around I would be happy to buy it.
Cheers,
Tore

Thanks BigMikeATL for your comments. As ToreB says, now all seems much more clear: " 0.0 or P means that something is very wrong inside the tacho "
I will ask the cost to know temperature and consumption to Mr. ebay..... but as commented it has more sense to spend money to improve others topics on the car

I could kick myself for passing on a couple of them for 200 and 300 because I thought they were too much.

For the moment, I will use this money to adapt the air-conditioner to the gaz R134A, according to european regulation.....
And regarding OBC, I will take time to investigate more and even remplace some transistors like BS170 N-channel FET, just in case.....

A customer of mine have now handed in a Tachometer with the OBC reading 0.0. I have a test rig for the tacho, and the unit behaves the same in this as in-car I therefore suspect there's no problem in the car. I've done some work on it to find the fault without results. Adrian Streather's book mentions a possible faulty diode 1N4148 on the LCD board, (he has wrongly called it 1N4118) I have changed it with no results.
I would be very happy to receive some info on how to fix this.

Where can I find the information in Adrian Streather's book about the possible faulty diode 1N4148?
My OBC indicates "0.0" from time to time, a battery disconnect (reset) will solve the problem for a while.

I do not have the book. Ss far as I know, is this the diode placed on the LCD board, easily visible inside the instrument.

The HVAC explanation on your website helped me to change a broken fresh air servo. The German company that you recomanded "PARTIsan" refurbished mine.
Thanks a lot!

Finally I know what's the meaning of our "P" or "0.0" in our OBC : "corrupted memory", we need to change the memory and to re-load again the software.
here someone in France who can do it http://stationcompteurs.free.fr/accueil.html

A blinking P in the tachometer OBC display means that the inbuilt memory contents is indeed corrupt. I have now done several repairs of this, with great success. The memory chip has a finite number of memory read/write cycles, and fails over time. Replace the chip, load the correct contents, and hey presto!
