Hi. I have a 2004 XJ8. 3 days ago I had the air suspension converted, front tie rod ends, ball joints etc. The mechanic also found that the front brake line was leaking so he replaced it. The next day, I had tires put on it. Today it pulled this Engine system fault parking brake fault dsc not available limp home mode crap. Every day's an adventure.
I'm wondering if changing the front brake line could have somehow caused these 3 codes? Or maybe even putting on new tires?
I'm just a dumb girl but it seems too strange to have had all this conversion work done to be coincidental.

 

May have left door open / radio on / etc so flat battery.

 

You'll want to get codes read. I got this fault when my throttle body was going bad. Replacing it resolved it, but the codes will tell you what it is (assuming you have a check engine light on as well).

It sure is and I certainly will do. Thanks much!
