Thanks for the search and the info.

Just one curious detail: Amazon says " This does not fit your: 1998 Volkswagen Jetta." That's the 1K0 906 627 E. So I tried the 1J0 and 028 numbers—same result: "do not fit"

With five different part #'s:
"Manufacturer Part #: 7.02184.01.0
Car Manufacturer OE #: 1K0 906 627 E (Volkswagen)
OEM Part Number: 1J0906627A
Manufacturer Number: 7.02184.01.0
OEM Part Number: 028906283F
Manufacturer Number: 7.21895.55.0"

How do we know which, if any, is right? We know Amazon wants to sell stuff, and it says "…does not fit."

But regardless of Bezos' opinion, the 028 906 283F should be certified correct; it's stamped on the relay frame.

The OTHER electric solenoid valve on the 98 Jetta TDI is the 1H0 906 627 (EGR control, right?), and that part is what Amazon shows for the Waste Gate control. Maybe that's why Amazon claims it "does not fit."

This should be the correct part for the N75 waste gate solenoid; its part @ is 028906283F. Sold by Cascade German in Gresham, Oregon.

i have had lots of success just cleaning them up. run some MAF cleaner though it.

What cleaner do you favor?

Couple spritzes of carb cleaner and then a little brake clean to dry it out is what I do.

MAF cleaner wont damage any internals, brake clean probably would be fine too. Dam part is a mechanical part that sends a signal on contact. Its basically a relay but the switch is controlled by pressure. The part is so darn expensive, i just clean it.

The problem is they get weak over time, so cleaning them doesn't help for long.

most defiantly. These controllers will work with oil in the lines. Cleaning them often works but if its an electrical contacting issue within the relay, it needs replacing. A volt meter will tell that tale easily.
