Could be a couple different things. You could have air pockets in some of your higher cooling channels in the engine/upper hose. This usually happens when coolant is added to the system until it appears full and then capped off without topping off as the water pump does its thing or filling with a sealed attachment while the vent is open to allow the air out. Another possibility (although I'm not 100% sure if this issue dates back to 97) Audi/VW in many of their cars have A/C and engine coomibg systems somewhat intimately connected to each other and sometimes they have a quickly compounding problem when the fan switch eats it. It gets a little complicated from there with several different parts that can burn out in thus chain reaction that gets pricey real quick and calls for the majority of the front of your engine bay to be relocated just about everytime (in my own experiences with such issues). So lets hope that problem is more modern than 1997. Not sure if that waz any real help, hope it helped at least a bit.
So if I took out the thermostat for just the summer would that be ok or would it make things worse than they are
Sorry for the late reply, but I wouldn't recommend taking out the thermostat. Sometimes doing that can help a vehicle run cooler on short trips, but longer trips it can eventually overheat or if stuck in traffic, and that's with a car running like normal. One that's having overheating issues will typically have an overheating issue that now behaves a little differently. If the cause is timing that's too advanced or unmetered air being sucked in, there's nothing really that will stop the overheating from happening other than fixing the underlying issues.
