I definitely agree, sometimes a good washing helps, but for one of my rear ones, I sent it out to be "rebuilt", there are a few sellers on eBay that do it. I mailed them mine. I am going to send out the other side, as now in comparison, the one that was not rebuilt seems slow now also.
Anyone have a photo or know if this guide in this diagram should be inside the door itself towards rear of vehicle (at B pillar) for when window is DOWN, or is this guide for above the door and along the window when window is up?
If it's for the A pillar area, anyone know of any guide that...
I know this is super old thread but I saw that you are still active on here so thought I would give this a shot. I am also thinking of making our B4 wagon our toad but the only tow bar plate I found is Roadmaster 1219-1 at $400.
Did you have luck fabricating something?
Test battery as easiest test, these pull a lot of amps for glow plugs then cold start.
Next is test the glow plugs and their circuit.
Low battery and lazy glow plugs are any diesel's sweet spot for no start

A quickie check is your top radiator hose vs bottom to see if thermostat stuck open. Should show great difference during cold start then even out if thermostat opens.
If you begin fairly even then may be stuck open.
If you don't have a temp gun you can use hand touch but of course be careful...
