Have a 2002 Audi A4 1.8T Quattro and I started having problems with the vehicle a few months ago. It started with the coolant system , I got the fans and hoses fixed a few months ago along with a new battery and a few other little things and it started and ran for a few weeks but then the coolant started leaking again. It still ran so I kept driving it and then it stopped again. Got the sensor that it needed, started working for a few weeks and stopped again. Now it won't start at all and there is also no heat. I'm getting so frustrated with the car but I don't want to lose it. Im wondering if anyone in the GTA knows any good shops in the Mississauga/Brampton area I could take it too that won't charge me an arm and a leg to get this checked out and fixed. Thanks again for your time really need help with this.
