[Vwdiesel] Never Trust a Dipstick

[Shawn Wright]

I read this after my last message - congrats indeed! :-)
Sounds a lot like how I felt after finally solving my ECU troubles on my WBX after 
about 4 years of intermittent problems! 
Now I will just have to remember this lesson when it comes time to fabricate a 
dipstick for my project - I was hoping to use a stock Jetta one bent to the right angle, 
and perhaps extended as needed, but I will have to very careful with measurements.
