I doubt your thermostat is bad.. If you aren't overheating, I wouldn't worry about it....
Depends on whether it's stuck open or closed. If open your coolant is constantly being cooled, hence the effect of using the heater causes the temp to drop and when not in use for it to rise. If it's stuck closed then your engine could overheat.LNXGUY said:I doubt your thermostat is bad.. If you aren't overheating, I wouldn't worry about it....
Excellent ... I'm glad you solved your problem, too!amgad said:To everyone, changed the starter, works perfectly... for how long, dont know.
Someone else try...
4th generation golfs have been marketed since Nov 1997, mine is october 1998. With respecto to the starter, my old starter seemed to start fine too, but its not until you change it that you notice the difference.mailman said:Excellent ... I'm glad you solved your problem, too!
I couldn't help but notice that your profile indicates that you have a 1998 Golf IV TDI. Is that correct? Did VW market fourth generation Golfs in 1998?
I'm thinking your problem was different than that experienced by the remaining 99.5 TDI owners. Just a hunch.
Anyway, congratulations on your fix!
Hamman mod has been working flawlessly for my 99.5 TDI!
My problem definitely was not related to the starting system. My engine cranks over fine ... it just wasn't starting! My starter and battery are in good condition. It is definitely injection timing related ... glow plugs can't be helping because they don't have time to warm up. I mean, I hit the button while cranking and the engine now instantly springs to life. Very dramatic difference compared to before the Hammam mod.
Keep up all the great posts!
Yes, I also have a 99.5 Jetta TDI with the same annoying long crank to start when hot. It did seem to get gradually worse over time. The car is running with the fuel injection advanced (above the graph) and I was considering changing the timing (I have Vag-Com). I will probably change it anyway, but I like the Hamman mod. I have been dealing with it for deals. I have a 1000CCA battery and I believe crank speed is fine.mailman said:Am I the only one who is noticing that every post about the hard starting when warm has a 99.5 model?
I'm almost certain it is a timing advance issue, and maybe the 99.5 models got stuck with an old software rev that was updated for the 00 and up models.
Just a theory.

I have to open the door open to hear the turbo. I'm a ex-biker and muscian and after toooo many live rounds I can't hear some things but I can tell you this when the Turdbo stops doing it's thing... I can Feel it!chromeBuddha said:Also, as a person new to TDI, I have read about people enjoying the sound of their turbo when they let off the gas...but I hear nothing. Is no noise a problem???

This sensor (038-907-319) is located on the front of the engine block down in the area of the oil cooler.ta79pr said:where is that sensor, behind the balancer?
Has anyone changed one?
