Default Re: (Hopefully) buying E46 w/ ~90k miles. What maintenance / mods should I do first.

Do oil analysis.

If clean, do vanos/subframe/cooling system (all in budget if you DIY).

If bad, do rod bearings and then vanos, subframe, and cooling system in that order.

Once funds free up, bushings/bearings/ball joints and shocks to get her back to driving like new.

If not done yet, rod bearings when oil analysis tells you it's time. Model year has nothing to do with it.

If that's the case, why don't you all sue BMW?

Rod bearing issue -> BMW recall -> still rod bearing issue = Class Action Lawsuit?

The recall existed because bearings in some 01-02 cars were not manufactured to BMWs specs.

Those cars have been recalled and replaced with bearings properly made to BMW's spec.

03+ was not subject to this. The cars that were subject to it have been addressed.

At this point we have normal high revving engine rod bearing wear intervals. The bearing in the 04 s54 in my wagon and 05 s54 in my coupe both wore out rod bearings (which was indicated, accurately, by oil analysis).

There's no safety in being 04+, and no hardware change between 03.5 and 04 that should make you think there is.

Is there any maintenance record on it from who your buying from? That way you don't have to go into the buy blind without knowing how new and old things are.
Oil analysis to get a idea of the rod bearings. People on here breach rod bearings and it's annoying. Yeah take care of them but if it's not necessary at the time don't do it. Refresh suspension/bushings, and basic things like filters.

Lol, noob with 38 posts comes in here and starts acting like he's the smartest little kiddo in kindergarden when a well respected mod that's considered something of an authority on the e46 M3 and has nearly 39,000 posts tells him something that is widely acknowledged about our cars.

Look through the records you get. My rod bearings were done at 11k under recall, will be doing them again before 100k.

I think you should start with Inspection 2, and do an oil analysis and see what the results are.

If results good: vanos - subframe - cooling system - bearings.

Congrats on the purchase. I will be doing SMG to 6mt swap next.

So what have you learned from the bottom?
What level are you at now?
Here is what I learned from this forum recently, way too many armchair BMW experts/engineers going around commenting like as if they mastered E46 M3 generation..
It's pretty funny what people have to say, including yours.
