My Speedo needle is all the way to the right. I pulled it out and re-did all the solder joints. It didn't look like it worked. The speedo needle was stuck on 0 and I somehow got the tacho neeedle all the way to the right. But after some spirited driving on the way home. Both the speedo and tacho worked correctly. I then didn't drive the car for a week, and it reverted to this state. Any ideas? I looked at prices for a replacement cluster. NA ones were $150-$200, But the TT ones were $300+ What's the deal with that?
