That was just after doing a San Antonio to Arlington TX run, averaging 74.6 MPH. The highway mileage wasn't the problem, but the city mileage dropped from 17.8 down to 15.4mpg. Those pesky vacuum leaks have a way of really screwing things up


Just picked it up from my friendly neighborhood dealer this morning and can tell a pronounced difference already.

Think of it like this: you can take 8 AA batteries in series to get 12v but of course that won't start a car. Your battery was similar, voltage no current capability. The thing is: when voltage is high, no charge will go back in so normal use won't fix it.

There are techniques that will bring a battery back from the dead but mine was old enough and I wanted to upgrade to AGM

Yeah, last time it was in the shop I was told that the battery will need changing soon.
Brought it back and got $17 core charge.

Time for the refreshes!

For the 4.4, all hoses, belts, pulleys, water pump, and expansion tank.

For the 4.8, suspension refresh. (Not pictured, the adjustable bits purchased from a fellow member)

Just a FYI for the Texas Mafia above, I just arrived in Austin and we are racing this week in COTA with Trans-Am and y'all are invited as guests of mine. I will be happy to put all of you on my guest list. We race Saturday but you would be on the list for the next 3 days if you want to come. I would love to meet you guys.

New rear brake pads, cleaned the speed sensors 👍

Smart preventive move. I just cleaned wife's aired sensor after getting trifecta

Thanks but looking for problems. I too think I’m dealing with the Trifecta issue that’s the reason for cleaning the speed sensors. My ABS, and 4 x 4 light are orange but my brake light is red. Trying to figure out what’s going on. It’s never gone into limp mode or fail safe, it drives normal. Taking it Friday to get codes read. I can’t figure it out. I’ve even changed the Actuator gear, and still no change. 🤦🏻 I love my E53 but it’s giving me a headache.

Brake red means hand brake activated or low brake fluid. A good scanner will show status of the hand brake not sure about fluid level lifting the cap will guy the low level switch. Also a good scanner will show wheel speed to help nail down that as a problem

The abs module itself has a design flaw that the bonding wires tend to break. Their are guys out there who know how to do a proper fix.

Just sold her after owning for only 4 weeks. She needed full suspension refresh and I felt that I am not ready to make that kind of commitment at this time in my life.
She went to a total Bimmer Head.
