Hello! I’m owner of a skoda Felicia MKI since 2 years, when I bought the car, came with the dashboard with clock instead of the one which comes with Rev counter. I bought another with Rev counter, but the fuel and the temperature gives wrong data. In my original dashboard the fuel gauge works properly, and the temperature also works. My question is... is possible to swap the gauges that works properly into the Rev counter dashboard? Because the counterkms, is easy to swap, just 4 screws.... or replace the clock for the Rev counter.... I’m a little bit lost

 

 

Any help will be much appreciated

You cant replace the clock with the rev counter, because of the gap for the digital clock, also it will be set up for the clock mechanism not the rev counter. You could try swapping the fuel and temperature gauges out though they just unscrew as its all modular.  It might be worth putting the old odometer back in as you will get the right km or Miles (depending on your country) that goes with the age of the car.

Thank you very much for your help! I didn’t tried to press the gauges out, loosing the nut, I pressed a little bit, and it’s out!

 

this picture is the result!

 

i will post another when installed and working!!

Glad I could help, I cant guarantee changing the gauges will fix the fuel and temperature gauges, but its worth a try before writing off the rest of the new unit.

In the theory, must work, because those were working properly. Let’s see

True I hope it all works for you.

You didn't mention what type of engine your car has. MK1 is not enough.

Sorry! 1.3 carb

Both gauges wrong! The car is just started, is impossible the overheating, and the petrol, has 1/2 tank.

maybe the motherboard of the dashboard gives wrong data?

I did say I couldnt guarantee it would work, I think it might be the electronics of the new panel, but I couldnt say for sure.  

@Cae449 and @lotrjw

There were about 20 different Printed Circuit Boards (PCB for short) for the entire range of Felicia models depending on period of manufacture, engine type (1.3 carb, 1.3 BMM, 1.3 MPI, 1.6, 1.9D), and equipment (LX or GLX). There are 3 or 4 different types of gauges for coolant temperature and fuel quantity too. So for a perfect operation of all gauges and without any modifications you need to find an instrument cluster that matches the period of manufacture and the engine type. Cae449, in your case you have to find an instrument cluster from a 1.3 Felicia MK1 GLX on carburetor. Otherwise you'll need to make quite a few modifications on the PCB that require good skills on electronics.

It looks like I got away with the change I did last year then when I got a unit that had the yellow fun dials instead of the standard grey ones. Both the old and new units had a rev counter though so that might have had something to do with it. 

Felicia Fun and Felicia 1.6 share the same engine, only different body. Since both cars had been manufactured in GLX option and in the same period, the match was perfect. Otherwise not.

Ah I see so if I had had a different model, I would have had to get a standard version that had a rev counter and the fun one. Then use the fun dials with the other board that would have fitted.

I am pretty sure that the temperature gauge will now operate the other way round so as the car heats up it will go down 

If that's the case invert it's polarity  and it should be OK

Is there any proof to back your advice? Because I call it a wrong advice.

Based on what I've seen from aftermarket temperature gauges that is the case. Also most of the analog coil operated gauges I ve come across would not be harmed by reverse polarity onto their coil circuitry. Nevertheless I do not know what kind of circuitry is contained withing the felicia gauge but I doubt it would harm it if he tried. 

My idea would be confirmed if he left the car to warm up and checked the gauge. If it actually drops then that's the case

Actually the temperature gauge will never go backwards on Felicia. The difference will be that the gauge will not show the correct values due to different coil resistance. See actual schematic below.

It doesn't matter if you have pre-facelift or post-facelift model, it's about model year. Since model year 96 (in manufacture from summer 1995) there was different tank sensor used. Another difference is between SPI and MPI, SPI uses different temperature sensor (two-pin) than MPI (four-pin). Not sure which sensor is used in carburator variant.

All coolant temperature gauges on Felicia need a 2-pin input (a thermistor with one pin to ground as in schematic from my previous post). It is not relevant for this topic if the sensor has 2 or 4 pins. The extra 2 pins go to ECU. The only relevant thing is the thermistor has different values and characteristics for SPI, MPI, and carburetor engines.

And? Does this somehow change physical appearence of MPI sensor? That's only thing I was talking about...

based on that he can add a resistor in series with the NTC to calibrate it
better yet add a 8 turn rotary pot and fine tune it

I think you missed the relevant for this topic part from my message. Chill.

What if the calibration needs a lower resistance thermistor ? Not to mention you can't change the shape of the temperature/resistance characteristic by offsetting it with a resistance because the shape is not linear.

Yes in case it needs a lower voltage you would need to adjust the other coil. The one with the 8v applied on it. 

As for the shape  that Will cause it not to read right but you could calibrate it properly for one temperature possibly 90
