Ok, I did look for some of these answers prior to posting, but I could have easily missed.

02' A4, 1.8t 130k miles

1. No Heat, I took it to a shop and they suggested flushing and using CRL, has anyone heard of this? He claims to have luck as the CLR would/could remove any blockage?

2. THe power window and lock buttons kinda stick, and occasionally push hard, any way to clean them?

3 What kind of lubricant can or should be used on the sunroof rails?

4. Valve cover gasket replaced? The shop said kind of a common problem with "seepage" worth replacing? They said even after replacing it still may seep a little?


Love driving this car, previous owner did not take care or keep it maintained so i need to catch up on the maintainance....costly but worth it...

 

Silicone spray lube for tge sunroof rails

valve cover gasket WILL leak again after a gasket job. (done mine twice already)

 

Valve cover won't leak if you do them right..... you need to put a small amount of black RTV on the corners and lightly over the half moon. And let the sealant cure, let sit for atleast 4 hours without starting the car.


If you have no heat..... flushing the core is the first step..... as well as properly bleeding any air out of the system
