How long does it take to replace a catalytic converter on my BMW?

The time that the job takes will depend on a number of factors, like your vehicle's make and model, year, as well as other factors. Select your car at the top of this page for information on job time and cost for your vehicle through ClickMechanic.
How often should I replace the catalytic converter on my BMW?
Catalytic converters are built to have a long lifetime, however over time the pores can become clogged, or overheating can cause physical damage. A damaged catalytic converter will emit more toxic pollution into the atmosphere. It is important to ensure the catalytic converter is always serviced as and when stipulated in the guidelines set out by your car's manufacturer.
How to protect your BMW Catalytic Converter from theft
There are ways to prevent the theft of your catalytic converter, mainly by making it harder to access and remove it. Below are a few suggestions on how to deter thieves or at least slow them down:
- Parking closer to walls, other vehicles or close to the kerb, to make climbing under your car more difficult.
- Marking the catalytic converter with an engraved serial number can allow easier tracing as well making it harder to sell
- Welding the bolts if the converter is bolted on. This does not stop thieves but makes it harder to remove the converter using only a spanner. The downside to consider is that it not only makes it harder for thieves but also mechanics when they are working on your exhaust system.
- Get a protective cover fitted to make it more difficult for thieves to remove the converter
- Get a catalytic converter alarm which is set off when the catalytic converter is tampered with
- Increased security measures, e.g. if possible park in a lockable garage, fencing, park in well-lit areas or CCTV ?
What is the average lifespan of BMW catalytic converters?
Catalytics converters usually last 100,000 miles or even the entire lifetime of the vehicle, however this can differ depending on how and where you drive, and other internal and external factors.
