If I'm not mistaken, the fuel-water sensor(fuel-water separator is a small
white tank located just in front of the passenger side rear wheel) will cause
that LED to blink as well.

There is a drain pet-cock on this tank which I would always drain a bit when
changing oil. If you (or the PO) haven't worked this valve before, it can be a
real bear and you might just break it.

I have installed 5 new gages & all are now working: volt meter, pyrometer, boost gage, oil pressure gage, & electric temperature gage with the sender in the hose leading from the expansion/fill tank to the engine. Have installed a two position switch so I can manually turn on one or both radiator fans. Took it to my mechanic who is working on some of my other cars & he diagnosed it as having a blown head gasket, which I have suspected as the Quantum still overheats despite both radiator fans running. I want to do all the work on my VW diesels myself. 
> I have R&R'd the head on my '81 Dasher diesel which does not have a turbo. The Quantum does have a turbo. Do I have to remove the turbo before removing the exhaust manifold? The Dasher has an inspection hole on top of the flywheel so you can turn the engine to TDC but I don't see one on the Quantum. Is there one there? I have the tools to lock the cam shaft & injection pump in place, for the Dasher at least. I assume they will work for the Quantum. Correct? How do I lock the engine at TDC? Same as the Dasher or different procedure? While I am at it, I want to change the timing belt as I suspect the prior owner neglected changing it although he claimed he had it done.

> My Quantum appears to handle nicely, as nice as my Focus ZX3 & with as much snap too. I think I agree with Brian Decker about running the Dasher & Quantum instead of buying a new Prius or TDI. However buying a new one is out of the question unless I can sell a couple of my collector cars, which do not depreciate. I bought my 2001 Focus ZX3 new for only $11,643 including tax & license, half of the cost of a then new Prius or TDI. With 114,000 miles on it, it is still running dependably & so far, has been the most trouble free car I have ever owned. Only complaint is its gas mileage STINKS! (24 to 28 MPG & an occasional 30 MPG).
