The temperatures on my bamboo pod shows for air-,oil-,watertemperature and oilpressure
wrong temperatures. When car is cold, garage temperature is 15 degrees, but air shows 27, water 44, oil pressure 16 psi and oiltemp 3 degrees C (car cold, engine not running, so all temp should show nearby 15 degrees).
If i start engine oil pressure is frosen in, showing same as before without engine running!
If i disconnect and reconnect the dash Ecu, P/n ME 658, sometimes temperatures change to other digits.
Now i have nearly temperatures within range, oil pressure working again,only oil temp shows 15 degree too cold and air temp is 55 degree too warm.
all others are acceptable now. Car starts fine, no problems at all

What i have checked up to now:
Footwell big fuse, main earth behind batterie and engine earth at starter are ok, not corroded and proper fitted.
I checked black and red cabes at the ecu, all showing correct voltage over 12 volts.Main bulkhead connector checked,
nothing abnormal found
No water ingress ever had.
Dash ecu send to Paul Smith, no fault found, should be ok!

Has anyone a dash ecu to sell or will he lend me one for testing (expenses will be paid from my side)
or does somebody has had same or similar problem.

Any answer higly appreciated, its a long way from my home to any specialists, because i live in the north of Germany 60 miles
away from Hamburg

Kind regards

Uwe - think you posted on FB Tuscan pages as well?

OK, if you've had dash ECU checked by Paul Smith then guess you can rule that possibility out of the equation?

My only other thoughts are to replace the oil temperature and coolant temp sensors? If I remember from FB, you said car was parked in direct sun?.....Would it be worth trying to spray an electrical contact cleaner into the area of the pod where the gauges are?

Hi Nick
Thanks for your answer, i did not wrote in any other forum about my problem.
So somebody else has had this problem? Would you try to get contact to him and show him this topic.
Maybe he can help?
I have send my Ecu to Paul, i fully trust him, but all electrics for the Mk2 are not bulletproof, maybe interferences,
cold welding points, something between earth and sky we do not understand, can be boken.
In the past I have had Alfa Romeos and other Italian vehicles, if something was not working, no worries, next day it worked fine again and this fault never happened again.I had a Laverda 1000c, if only a few drops rains coming down, engine was cutting out, if rain has stopped the bike started again and drove without any faults again. Conclusion: Humidity and barometic pressure are not same as south Italy (was an imported bike for south Italy).

A car is not a women, a car needs love!

Therefore i would try another Ecu for testing only to be 100% sure that my Ecu is ok!

Uwe, I was thinking about BAUKE TOCUS on the Tuscan pages in facebook.

Have you plugged diagnostics cable/software into the car's main ECU to check values there? If the dash electronics are fine then it's maybe the main ECU that's feeding it junk?

Values are ok at diagnosics, only the values are changing to irrational numbers on the pod screen, the MK2 has a seperate ECU for the pod.
This Dash Ecu gives the numbers to the pod.
