GTI speedometer and TU3M

If you see wires, but still have your hands clean, that's the right forum.

Hello,

since friday my 309 is back on the road until october! Yesterday I have finished my speedometer conversion. The oil pressure sensor from Conrad Elektronik works with the GTI-speedometer, but not perfect. The warning light is working like original, but the clock goes at 8 bar marker when I switch the key on position I or II when engine is off. When the engine is on, the needle goes to 3 bar when driving and 5 bar when the engine is working in idle. Is this correct?
The next problem I have ist the oil temperature. I used the original sensor from Peugeot (new part) and put it on place of the oil drain plug. When I´m driving the needle from the clock doesn´t go over the 80°C marker. Is that with you too? Is it perhaps the wind?

Regards,

Thomas

Hi Thomas!

Your trouble with the oil pressure sensor seems to be a bad polarisation. In normal operation, when cold and idle, the pressure is about 5/6 bars. When your engine is warmed and idle, the pressure is about 2/3 bars.

Your oil temperature really depends on the way you drive, the kind of engine and your collant liquide temperature.

On my GTI, the oil pressure is allways a little bit less than the coolant temperature. About 85 degrees (averaging on a year, winter and summer included).

Malik should give you the values he has on his Vital, which is TU equipped
