When that fails, use a mini-cat to extend the life a year or three

I'm doing this as preventive maintenance as I don't have any real catalytic issues, probably since I run 99% of the time on 95 benzene and the other odd times 95 gasoline. (Fingers crossed)

Replaced driver side rear shock and most of the parts attached yesterday, doing the other one today. It'll be interesting to see if there is going be any noticeable difference while driving. At least the shocks were pretty rugged and most likely were original to the car.

Oil change, a little overdue @ 5700mi, old oil black as night. 7.5L of Liquimoly 5W40, Mann filter, replaced the o-rings. https://www.fcpeuro.com/products/bmw...27512300kt2-lm

The windshield washer pump seems to have just failed. It was working last week. Grrr. Hit the headlight washer button, heard the pump run a bit, they sprayed a little then stopped. Just ordered a new one...

As annoying is that is, you're lucky to be working on e53! E70 need to remove the whole fender to change washer pump/gasket

That can also be a symptom of a leak letting air into the line from a wiggled off hose clamp. Something that has happened to me after an oil change...

Do all 4 corners and your vehicle will drive like a totally different one in a nice way. Be prepared to be wowed :D.

This started Friday night after it'd been sitting at the airport for a week in the blazing sun. I landed pretty late and it was still an oven inside. Windshield was pretty dusty so washy-washy time. Oh. No washy-washy.

So I hope it's just the pump... those failed annually on my prior Volvo 240.

Coli or Airbag suspension?

Finding shocks for airbag suspension is getting hard.

The car is a mind reader, I swear. I thought to myself as I was swapping the right steering knuckle in a couple weeks ago: “boy these wheel speed sensors last a long time”.

Yesterday I was rewarded with the amber trifecta and inop speedometer. The foxwell confirms a left rear wheel speed sensor code and “0” mph on the live data on a drive around the block. Unlike when the DSC module crapped out, the car drives fine so at least I didn’t have to pay for overnight shipping on a replacement. The rears are relatively inexpensive so I bought two, and two connectors which get very brittle. I sprung for one front sensor, which are more pricy. I’ll replace the left front when I swap the “new” knuckle with bearing and ball joint in on that side. It’s built and ready to go when I find some time. The eBay knuckle came with a sensor hanging on it, so I’ll consider that a spare for the front.
