Mk4 computer repair
 

Has anyone in the US found a repair shop that can work on the Mk4? Seems to be lots of options in Europe but I'd like to see if I can find something closer to home. Thanks!

what are the fault sypmtoms?

"Error reading CD/DVD" I tried using the DVD from my E39 and get the same error so I assume it's the drive.

BTW I also tried an old CD and got the error message no disc in the drive.

90% chance it is the laser

Buy the laser from the Dutch shop, and then take laser and nav to a local electronics firm that has experience replacing lasers in DVD mechanisms.

This is a cheaper way then replacing the whole nav.

Thanks will do. I've found a few places that claim to repair nav computers but no one was less than $600.00. The Dutch guy will sell me a new drive and laser for $225.00 and he says I can replace it myself so we'll see. I'll post how it turns out.

Extremely easy to replace whole drive:

1. Remove top cover of nav (clipped on)
2. Remove 4 x torx screws that hold nav drive in place
3. Unplug nav drive connector
4. Fitting is a reversal of removal

I just did it:

My MK4 was starting to die

And your MK4 is back new again. Since then he is much faster and no reading errors anymore.
