Starting Problems 1994 Jetta Diesel

My Jetta has been getting harder and harder to start lately. I let the glow
plug light go out and some times it still won't start till after quite a few
tries.
Some times it will start on the first try and then some times it will take a
dozen tries to get it started.
One other side note, the odometer has reset itself back to approximately
3000kms and has been going up from there normally?

Any insight would be greatly appreciated.
Thanks in advance

Can we assume you are not living in a part of the world that is
currently cold? I never had to use glowplugs on either my 76 or 02 diesels.
The new one will not even turn the glow plugs on above 40º F.

I believe injection timing, compression and starter speed all can cause
problems.

All VW diesels use their glow plugs, even de most recent TDI's, even
when it is 30 degrees celcius. They will glow for a very short time and
the glowplug light not being on does not mean that the plugs are not
glowing. My 91 Golf diesel used the glowplugs for 3 minutes after the
engine was started, but the glow light went of after 7 seconds when
turning on the ignition.
Direct injection diesels do not need glow plugs under normal conditions,
the only reason they are used is environmental...

What would make the odometer reset itself?

In the Mk3 Golf/Jetta the odometer goes to 0 after 300.000km. Why? I
don't know, the older mechanical counters went to 999.999km.
