Just received BD order and tested VDO 300F gauge and FAE (says made in Spain) sender 049 919 563 A

With the same setup as testing the FLAPS gauge, a reference meat thermometer and the sender in a kettle of water, the VDO gauge seems more accurate. Remember from my other post that the FLAPS gauge showed 20F too low.

The VDO gauge is a bit of a mixed bag. To damp needle movements I suspect is uses some mechanical viscous mechanism built into the analogue instrument. (Modern designs would use an electronic filter) This damping� may also� have a constant sticktion giving the meter a bit of hysteresis. 

Results from temp testing:
VDO������ True

180F������� 190��� on� slowly rising temp

180F������� 181���� on slowly falling temp
~200F����� 207F� Boiling water at 2000ft alt

(VDO reading of ~200F is visual interpolation between 180 and 220 markings)

Gauge markings are 120, 180, 220, 260, 300
The scale is non-linear and 220-260F is given the most space. It would have been nice if VDO had printed 3 thin lines for the intermediate 230, 240 and 250F temps.

Update to below:

Busdepot indeed has VDO gauges. I just had difficult to use the search feature on their new web page.

Fred, their customer rep, said tghe following pair would work, so I ordered that + some misc stuff I needed.
VDO Oil Temperature Gauge ��� 310012 ��� 1 ��� $24.95
Oil Temperature Sender ��� 049919563A ��� 1 ��� $5.15

Shipping to Canada expensive, but more reasonable from BD than many other US sites.

I'll update on the gauge/sender accuracy when I receive it. (As I posted the generic FLAPS gauge/sender combo I bought showed 20F too low, so I decided not to use it)

Will take a trip to Waterton/Glacier NP this weekend.

Hi,

After the overheat issues with my 1.9TD Westy I wanted to install an oil temp gauge as a 2nd check on temp. I bought a "universal gauge and sender kit" from the FLAPS (Princess Auto), but the sensor thread was 1/8" - 27 thread and and VW wants 10x1 mm. 

I found a post on vw vortex saying I can just use a temp sender :

http://forums.vwvortex.com/showthread.php?4747075-Want-to-install-oil-press-temp-gauge

What do you think about this?

Appealing for me because the temp sender I probably have among spare parts in the garage or it is listed at� busdepot. (I searched for a oil temp gauge kit at BD bud didn't find one)

What I'm concerned is to get a temp sender that somehow has the wrong electrical properties. Are the
 sensors pretty much the same and it is just the gauges that vary? Or do I have to match the sensor to the gauge?

Tips for where I can buy a metric inexpensive kit in Canada would also be appreciated (ie Pricness auto, parts source, numper to pumper...). If I find the right kit I'll return the kit with the 1/8" sender� and get a matched sender and gauge)

Martin (and '82 Westy 1.9TD)
