2006 V70 Dim Repair

Folks,

Hope summer is going well for all of you in the northern hemisphere,

About a month ago my 2006 V70 (~176k miles) started showing all sorts of weirdness with the dash. Speedo working intermittently, tach too, displays wonky, gas gauge and temp too. Only the information display on the left hand side has been rock solid.

Watched some videos on the reflow process (my intended approach was to use a soldering iron with a fine tip, not the heat gun reflow approach) and most of those videos show an early circult board vs the one I have (I have the year/style where you have to pull the needles off the temp, gas, tach and speedo).

Does anyone know of a video for the later style or have experience doing it?

I've done this sort of thing to a couple of car stereos and laptops with positive results so I'm not concerned about that, more about which elements I should focus on.

This one suggests touching up all the resistors and leads from the plug, which is where I am going to start, but eager to hear of anyone's experiences.

Relatedly, what's the trick to removing the needles from the gauges? I can't seem to get them off and haven't yet wanted to resort to trying to pry them off.

Pry them off, but if I remember correctly you don't have to remove needles on 05+ DIMs.

There was no way to get the board off without prying them off. So I did. Reflowed the solder on all the larger resistors got things back together and it seems to be working OK. I was a bit off on the needles, but got them closer after some experimentation. Now my only issue is a passenger air-bag is disabled warning (must have happened when I reconnected the battery ground - which was a surprise as I followed the SuperHerman instructions to a T). Might have been because I had some stuff on the passenger seat.

Anyway, chasing problems with my VIDA VM after I spun it up to clear the airbag warning light. Sigh.

And got my VIDA setup working this morning and cleared the codes. Everything is working as intended.

Sadly, after about a month of bliss, my DIM is acting strangely again. Same symptoms. Well, it gives me the opportunity to get in there and adjust my temp gauge needle (it's about 1/8 of the scale low at normal operating temps).

Hey a3inverter,

If you decide to not fool with it yourself any more, I would encourage you to give my post on this topic a read. I'm still driving the same V70, and the DIM is still going strong.

Driver Information Module (Instrument Cluster) repair options?

All the best,

Jonboy

Jonboy - I may ultimately take that path, however I did some additional work on it a few days back and all is well. Fingers crossed
