I believe that this has been covered in the HUGE cluster conversion thread found here, shorter version found here. Another thread to look at is this one by Nihilator. It is an AMAZING FAQ with a lot of information. This thread is specific to just putting a gasser cluster in a TDI.
Can I put a gaser cluster in my TDI?
The short answer is yes. Jetta / Golf instruments from a gasser will work in the Jetta / Golf TDI. A Passat cluster will not. Although I'm sure that a Passat cluster from a gasser will work in a Passat TDI, but I don't know anyone that has done that.
Can I take the MFA display and put it in my current cluster?
No. The MFA board is completely different than the standard cluster.
What about the tachometer?
It shows your RPMs exactly as it should. The only difference is the scale. But if your engine is at 2000 RPMs, the pointer will point to 2000 RPMs.
And the Speedometer?
Same as the tachometer. If you’re going 60 (mph or kph), it will still point to 60.
And the glow plug light?
For IMMO2 clusters (2000, 2001), the light is in the same place. But instead of the pigtail, it shows as EPC.
For IMMO3 clusters (2002+), it’s tricky. The LED (physical light) may or may not be there. If it is there, the tachometer face is blacked out in that spot. You could either run some wires to a different spot that will show through and put the LED there. Or you could poke some holes in the face to let the light shine through. Both of these work, but I didn’t like either one.
The third option is to have a pro go in to the eeprom dump from the cluster and change the tachometer scale to a TDI scale and then you can take your TDI tach face from your original cluster and put it in the gasser cluster. I suggest that only the pros do this. If you are confused about this in any way, DO NOT ATTEMPT IT. You run the risk of bricking your cluster.
How accurate is the MPG display?
Depending on your car, it will read 5 - 10% high. The IMMO2 clusters can be programmed with VCDS (VAG-COM) and adjusted by 5% increments for your car. The IMMO3 cars require a change in the eeprom dump. I’ve gotten mine to within .1% of actual mileage on an IMMO3 cluster.
