My 2000 S had pixels in n the center LCD screen so I replaced all 3 screens and all seemed to be good until I drove the car.

I assume I damaged something on the circuit board during the repair but before I bought a used replacement I thought I would check here.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

If so, try to find a gauge clauster repair shop, which can fix that for a reasonable price.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My 2000 S had pixels in n the center LCD screen so I replaced all 3 screens and all seemed to be good until I drove the car. The tach reads (mostly?) correct at start up, but every time I accelerate it moves slowly up about 2K until it top out at the end of the range then it will stay there. I assume I damaged something on the circuit board during the repair but before I bought a used replacement I thought I would check here. I triple checked the connections and they are all good.

POST 2Original post

Did you touch or lift the needles? If so, try to find a gauge clauster repair shop, which can fix that for a reasonable price. ~ 200-250$ How do I know? I swapped my center tach gauge face and had a dead tach needle afterwards.

POST 3Original post

I had a similar problem when I changed the dials. You have to turn the needles from the highest value to the lowest while simultaneously pressing it into its seat as you do so. I was reluctant to do it, but it worked afterwards.
