Our odometer went nuts and eventually quit. The speedometer followed suit. Both are now lifeless. In reading old posts I see that the replacement is VDO 437152. This model measures to 80 mph. The speedo in our rig was replaced with a model manufactured in 2001 and measures to 120 mph. It also has a very different VDO number (M211 012 073 and 01 112 261). I plan on replacing it with the 437-152. Any reason not to? Thanks.

jor,
Perhaps there is someone here who has done this. Don't know.
My advice would be to call VDO on Monday and ask.
my VDO odometer has quit and shows something like 999999 or so but speedo works fine. I also have a bum water temp gauge but as I use silverleaf I have not bothered with either so far but will. Let me know what you do with your speedo (and do not mean shorts!!)

Howdy Jor, I replaced both my VDO speedometer and tach. They set odometer and hours. I used these guys. Great service:

Good Luck, Dave A
John, ours are:
Speedometer: VDO Vision, 3-3/8, VDO YS437-152D 85mph Tachometer: VDO Vision, 3-3/8, VDO TP333 162D 3000RP We also fine-tuned the speedometer setting with a GPS.
Thanks to all. I'm adding this to my list of projects to be completed when we get back home. For now, the GPS will have to do.

At 60 mph you are 1/2 the 120's speedo range. Needle verticlel
On the 80mph one at 60 you are 3/4 of the scale.
Your brain says you are gong faster
FT has many of these RV's wired so that full 12v goes to the light bulbs in the Tach and Speedo. This makes a lot of heat and I think leads to their failure (lots of people have had failures). I disconnected the mod when I installed new speedo and tach.
OP here. Ended up installing a new VDO 437152. The rig is up on the blocks so I can't test it but it does the needle sweep and displays the mileage (guessed at it). The other one sometimes displayed the last mileage and at other times only an error. I'm betting I'll have a speedometer next time.
jor
John, how did you set the odometer to your 'guessed' mileage? Your new spedo looks just like our original and our replacement.
I had the vendor do it.
jor
What vendor did you use for the speedometer?
My speedometer failed intermittently so I messed with the wires on the back of it and the ground wire until it started working reliably again. It must have been a dirty connection or something. I just drove my coach 3,000 miles from Grand Canyon all the way to Maine with no speedometer issues. Have you checked the electrical connections?
I bought a tach and speedo from these guys and they programmed both (mileage and hours) Nichols Speedometer & Instruments - Speedometers, Tachographs, Service and... (http://nsifleet.com/contact.php)
My post info here: VDO Speedometer Replacement (http://www.foreforums.com/index.php?topic=25313.msg200169#msg200169)
Yea, that's the first thing I did. Matter of fact, I pulled and cleaned about every connection in the dash as well in an attempt to stop a beeping issue. Still working on that. I took krush's advice on the vendor and they have the best price. $109 for the speedo.
jor
Thanks Dave! I'm been looking for a Tach and that's he best price I've seen. May have to get off my wallet and get one. :)
see ya

I am about to repair/replace a second VDO speedometer (that I know of, PO replaced one). Speedometer still works, it is the odometer that went south. looks like it has a date code of 2011. The tach has a date code of 2009 so it was replaced also in my 2000 U295. Mileage and engine hours are incorrect.
Krush if you read this could you give more information and the possible fix you found.
thanks
Ed
Send it in to the closest VDO facility. Not too expensive and quick turnaround. I used these guys at least a hundred times in my grey market business.

This is an old post, Pierce. I ended up just buying a new one. They aren't very expensive. Worked great (once I understood that it needed to be calibrated!) Thanks.
jor
Jor I have a problem with 120 mph speedos. This use is barely over half scale.
The 80 mph one LOOKS like you are going faster.
Howdy Lance,
I replaced both my VDO speedometer and tach. They set odometer and hours. I used these guys. Great service:
Part Number Collection (http://www.foreforums.com/index.php?topic=11472.msg228057#msg228057)
I believe they will repair units as well
Good Luck, Dave A
Since this is the second speedometer to expire in this coach. I want to see if I can keep the new one from having the same fate. Would anyone else know what Krush was alluding to in his previous post. "Disconnecting the mod"
Thanks Dave, I'm only 3.5 hours from Greensboro NC. Nichols Speedometer mentioned earlier in this thread is a VDO dealer there.
Ed
My speedometer quit again, then it worked, then it quit, then it worked... (sigh)... I think I'll contact a couple of these speedometer rebuilders before I buy a new one. I'll also ask them about the modification mentioned on this thread.
Remember, It may be the sender or sender connections that are bad. Crawl under and check.
Pierce
Pierce,
Where is the sender located on the transmission? My speedometer works, but my odometer flickers
Thanks, John M
John,
Picture is worth a thousand words. See PDF below.
If your ODO has a problem but not the speedo, it may be in the speedo head assembly.
Pierce
Pierce,
Big THANK YOU for you help.
John M
My original VDO tach hour meter area flickers at times and it's brightness varies. Works fine otherwise
With a digital voltmeter, you might check the voltage coming into the illumination part if not an internal connection. Removable bulb? If so, check for corrosion. Even a little can make a bulb flicker. Otherwise, give VDO a call with the symptoms.
P
I think it's an internally lit area. Light is fine. No flicker. Just the digits themselves
Both my odometer and hour meter were weak and on/off. FT told me that was the sign of a failing gauge. I had them replace both before our Alaskan motorcade.
