Replace coolant reservoir cap. There is a defective seal that is keeping the system from pressurizing correctly. That will cause the coolant to boil out of the reservoir without leaving any trace of a leak.

I have a local shop ready to do a head gasket for $1600, maybe more. Would you do it?

I just had mine done for a similar head gasket leak. I could not confirm it with the combustion gas in coolant test or a compression test, but eventually dyed and pressurized the cooling system and found a small amount of coolant in cylinder 5. Had a slight miss in cylinder 5 a few months ago, but it went away when I fixed a broken vacuum line so I figured that was the issue.

My total came to $1669, but I recently had timing belt, idler pulley, and water pump changed. They redid the timing belt and idler pulley just because I couldn't locate my records to prove it and they wouldn't warranty the work if they didn't do it and I couldn't prove it.

I would do it for a 98 T5 in a heartbeat. I did it for my 98 GLT without hesitation. 98 was a great model year for these cars.

By the way this is my first post, but I've been lurking on these forums for a little while and using rspi's YouTube videos to guide some of my DIY repairs. I am almost to stage 0 and once there, I will start working on the paint and other little things that irritate me, but don't affect driving.

Last we heard it was losing coolant, it sounded like a head gasket but still nobody knew why. Did the shop determine the head gasket is bad, combustion gas test or some other method? Or you just took it in for a quote?

What brand water pump? Reason I ask is VW used to have some with plastic impellers - when they got hot the impeller would rotate independent of the shaft... Only seemed to do it at the worst time.
Wisdom requires knowledge as a prerequisite, but knowledge can be developed due to a lack of wisdom.
In order to learn how to fix something, you must first learn how to break it.
