Sorry for the post after a post. I really wanted to start fresh with this one.
Im sure we will have a few members pop in with help on this one. These two parts are some of the least sexy parts but they are very important and can effect the power you car makes.
First because its most important.
02 sensors
I know of several guys that have run into this. You can have one set of 02 sensors in your car and get one reading and then put in another possibly wore out set and get even different readings. Those of you that have seen this feel free to pop in.
The older the 02s get the more they tend to read off a little. This can really have a impact on how the car runs and how well the car is able to handle the much more aggressive transfer of power. Even if your 100% stock. If one side fails you might as well change both sides.
There isn’t a real good way to test the 02s to see how good or bad they are. Lucky for us the Vag-com tells you when they start to go bad. The only issue is at that point there already bad.
Will aging 02s really do major damage. Not really they will cause a power loss and in some cases cause your cars fuel trims to be out of whack.
The last one for today. Also can effect your cars power and also effect how your car feels and how your well your motor stays in one spot.
Its these. In case you didn’t know it this is what blown motor mounts look like.

Yes motor mounts. They can cause quite the issue when they are going bad. When they blow they can cause all kinds of issues. Including but not limited to a rough ride motor moving around enough to do damage and then sending signals back to the ecu telling the ECU that the car thinks its going over sever bumps in the road when its not.
