Message Hi guys, I have a 93 TT manual with 56k original miles on body and motor. I recently had the car dyno tuned at Z1 after a lot of major upgrades to the engine and every once in a while, the speedometer will quit working. Sometimes it drops to zero, sometimes it jumps all over the place erratically while driving. This only happened maybe half a dozen times. The more pressing issue is that the steering is very light at higher speeds and feels very uncomfortable to drive. At low speeds the steering is heavier the way it should feel, but high speeds it's very wobbly.

Does anyone know if it would be an issue with the speed sensor or the steering sensor? How do you diagnose these? If I need to replace both I will, but it seems silly to replace both if it's only one of them causing the steering issue.

Thanks!
