Hello gents,

I came from the E46Fanatics world as I had been on that site since 2005, and just lost my 2001 330i to a total loss accident. An 85 year old woman claimed her foot slipped off the brake and onto the gas as she shot out of a parking lot unbeknownst to me and crushed the right rear quarter of my car. Being an 01 with 236K miles (all maintained by me) insurance felt the car was pretty worthless. Took a few weeks and proof via many many receipts of parts (all my labor unfortunately) to raise the value to an acceptable figure. I was also able to rape the car for any other aftermarket parts I could unload so I did ok in the end.

Picked up my new (used) 2003 TiAg M5 with 79K miles about 2 hours away from home, but still in Mass. Wiggled on the price a little bit and in the end considering what I was able to get for my E46, I picked this up for just under 20K.

Small things I have done thus far to bring my thread up to speed:
1) Had to get new front tires (Michelin Pilot Sport A/S to match the backs that were new). The Fronts were older Michelin Pilot Sport A/S from back in 2010 and had chunks of rubber missing from the tread area, even though the tread was still deep, tons of dry rot and it made me nervous on a car of this caliber so I had new ones put on.

2) Installed the short clutch stop from the ebay user recommended on here, made that lower clutch pedal dead spot so much better and car still starts no problem!

3) Hardwired my V1 so I am protected or at least on the defensive end all the time.

4) Inspected all 4 brakes, everything looks good, washed and waxed with Klasse All in One before the winter comes.

5) Figured out a decent solution to the water pooling in the gas cap area, for which I will post up some pics soon so you all can see. Granted it's not an optimal solution, but with the door closed you can't see anything and that was the only area on the entire car where there were some small rust bubbles.

6) Got under the car to check everything out, repaired the lower right fender belly panel the best I could until I get a new one, and found some exhaust brackets totally rusted through. I have the replacements from FCP in my garage right now waiting to go in.

7) Found out there is green coolant in this car (YIKES!!!) and not OE BMW Blue. Have records from PO of thermostat being replaced around 2013, so that is new-ish, as well as the clutch.

8) Issues I am currently perplexed with: Strange hesitation sometimes in 1st and 2nd gear, I've read on here about this, seems better with Sport mode engaged, but does not feel like it drives perfectly in 1 and 2. The rest of the gears are good. I am exaggerating this issue, but there is definitely something up. Also the clutch makes a spring-like sound when depressed and released which I also read can be normal, but my bigger concern (hoping it's the loose exhaust bracket rattling) is that once 1st gear is engaged, during the process of engagement, there is a strange creak.

I need to get my airbag recall done soon, so I am hoping to have the dealer at least assess the car overall and take a peek at the 1 and 2 gear issue along with the clutch noise. We'll see what they say.

Otherwise this thing is amazing, it's literally my favorite car of all time, so much so that when my girlfriend and I were dating, she rented me one from a high horsepower rental place for like $600 for one day! It stuck in my mind ever since. That was back in about 2001.

Just rolled the ODO over 80K the other day. Oil looks perfect, no leaks anywhere from what I can see. Will try to post up some pics that are on my phone soon.

This is a great thread, wish that I'd stumbled upon it sooner! Thanks for sharing all of this info, it already answered a few questions that I had about the upper oil pan. My car is currently getting both timing chain guides & rod bearings and I'm almost in over my head.

Is there a consensus regarding washers for the dipstick and drain tube? Part number 11437838127. It's greyed out on both RealOEM diagrams but seems that some folks are installing washers anyway. Curious if it's recommended while you're in there.

Thanks again

yeah pretty sure I replaced that washer and it was there when I pulled the dipstick but this was a few years ago so don't quote me on that... was it necessary? probably not, but you know, it's cheap and while you're in there... these little "cheap" parts do add up over the giant parts list though.. best way is to find my original parts list on this thread and see if it's in there..

Cross referencing my other thread where I am discussing the car overheating here.
Adding the same pics here for reference.

Car will now have a new fan clutch, new fan blades, new expansion tank cap and I intend to pull the bumper off as well as snorkel and electric pusher fan and clean that AC condenser as best as I can this afternoon, hopefully that solves this overheating issue once and for all!

Ok so I went at it today, pulled bumper, electric fan and snorkel, removed intakes fam and fan clutch so I could push water through the back, soaked the condenser with foam tough stuff at least three times and used this very light pressure mist/spray tool that works very well on delicate surfaces with super hot water to rinse. It was not horrendous, but some pockets of debris and a lotta gray water and sand crud came out. Went for a test drive with the AC on and it was about 76 F out and really humid. Went to Walmart to get some washer fluid and I did see the coolant temp go to about 92 during around town driving. Tomorrow is the real test because it will be 87 and I’m going into the office so this will be a good test to see if things get really hot especially if I get any stuff and go traffic… I will report back.

Since I had the bumper and the snorkel off an electric fan, I installed my new hood in latch as well as cables and everything all brand new now for opening the hood.. opens like butter what a difference!!

Random find… was reviewing a listing for a set of M Parallels on bring a trailer but for an e31/e38. A commenter posted up that there was an e39 specific set on eBay currently for sale. One minor bend on one rear wheel and some light curb rash that appeared to just be missing paint chips. Price was good and free shipping so I went in! Will need to get them refinished but so happy as I’ve been looking for a set like this in OE forged condition forever…
