I also have a noise from under the right side of the engine area closer to the firewall. I have a MRT turboback exhaust. Mechanics have told me it was the downpipe that was rattling. I have my doubts. It sounds like a strut problem. but how do I diagnos this? I hear it over bumps and when going in reverse. Help me find this before I buy a new downpipe and see that the problem isn't remedied. I refuse to use a dealer to help me. The last time they had the car they didn't tighten any hose on the motor after finding an overheating problem and my I/C hose blew off at 19psi. I paid $198.00 to them for a themostat replacement.
