The Maltese Falcon

Dealer. As i said they reset the comp but it did not work. Just want to know if anyone had same prob so they can let me know how to fix. I asked dealer toi replace instrument panel and they said they will do that for me. My cuz had same prob wif his 200SX and he said that waht they did.

Hi, I have a 1999 R34 GT-T Triptronic. and the instrument panel has been playing up. When i am driving the speedo and rev meter max out and than everything on the pannel (speed, rpm, fuel, temp and odo) all go to zero (odo goes blank). After about 5 min the fule and temp usually come on first and than a few sec later the speedo and rpm will come back. When they come back they are way out. I will be doing 60 and the speedo says 120. If i keep driving it will max out again and repeat what i said eairler. Sometimes the engine light will come on for a few sec after the panel has died for a few mins but than usually about a 30sec - 1min after everything will flick back on again. Under 1 situation i actually lost 1km on my odo. I only purchased the car about 3 weeks ago and i have taken it back after 1 week coz this happened to me after the first day. They told me the comp needed re-setting or the battery needed changing. I left it overnight and they said they reset the comp. All worked fine till today. Anyone have any idea what it is and how much AUD$ it will cost to fix. Cheers
