Simple Answers from Griesbach Auto Service INC. for Weston: Exhaust Service

Some answers about exhaust.

Question

My car failed its emissions test – what do I need to do?

Answer

Let’s get this out of the way: a leak in your exhaust system could be deadly. If you smell exhaust in the passenger cabin or hear an unusual exhaust sound, get your exhaust system checked and repaired. This is important: Carbon monoxide in your exhaust is odorless, colorless and tasteless can be fatal to you and your passengers so don’t delay if you suspect and exhaust leak.

There could be several reasons for a failed emissions test, so some diagnostic work is in order. A common reason is that the catalytic converter has failed. The catalytic converter removes some of the harmful elements in exhaust.

When a catalytic converter fails it must be replaced, which isn’t cheap. Many people stop there – but the converter failed for a reason. There may be any number of engine run conditions that led to the failure. It would certainly be smart to have your technician diagnose the cause so that you don’t end up with another catalytic converter replacement down the road.

Oh, and that Check Engine Light that so many ignore: It might just be illuminated for a condition that could lead to catalytic converter damage. Have a service professional get to the bottom of any check engine light situation.

TSB, not USB

You probably know that USB is a computer term (it stands for Universal Serial Bus). But do you know what a TSB is? You should, because it could be important for your vehicle.

A TSB is a Technical Service Bulletin. Once a new vehicle is introduced and starts being driven by thousands of real-world users, weaknesses in parts or design are revealed. So, automakers send out TSBs, so service technicians will know to look for those problems. A TSB can be issued for things such as a loud noise when the vehicle turns or a minivan power door that won't close properly.

A TSB is not the same as a recall. If a vehicle has a defect that could result in people being hurt or illegal emissions, that vehicle is recalled. The manufacturer must pay for a safety defect to be fixed, usually at a dealership.

When a Technical Service Bulletin is issued, it's an acknowledgment that the vehicle manufacturer has noticed a pattern of something not working the way it should. They also suggest the proper repair to address these known issues. The cost for a TSB is usually only covered by the manufacturer if the vehicle is still under warranty.

If your vehicle is no longer covered by a warranty, but a TSB has been issued on a certain problem, any service facility can perform the service. Ask your Griesbach Auto Service Advisor about TSBs that may have been issued for your vehicle. Those TSBs can be helpful for the technician to diagnose any problem you are experiencing. The TSB will also guide the technician on the best repair procedure to get your vehicle working the way it should. We’re committed to maintaining your vehicle’s performance, safety, and fuel economy.
