My parents have a 2003 Jetta TDI. They have had the engine light coming off and on. JUST before the light comes on, there is a loss of power on straight aways and/or up hills, occurring at highway speeds. The next time they drive it, all is well again! It's a hit and miss situation. They took it in to have the code read and it's the turbo charger. We're about an hour north of Toronto, in Ontario.......approximate costs and mechanic recommends appreciated. Other than that the car appears to be in perfect order. Don't want to go back to the dealership as it's out of warranty.
