Lately it's been making a rattle when it is cold but gradually goes away when it warms up. Suspect it might be the exhaust or a heatshield attached or near the exhaust. I can feel it rattling against the body (or the harmonics are vibrating things around the body).


My exhaust does the same thing (eisenmann race) its never bothered me since it only last 2 mins on initial cold start. What brand is your exhaust?

It's the factory exhaust. Takes a few minutes but it does go away, hence my thought that it is the exhaust. Guess I'll find out why when she goes to the shop this Friday.

My previous M3 had that rattle issue, and the heat shield above the exhaust had a small tear around one of the areas the hardware affixed it.

Drop off the car at Tech Craft for Matt to do his magic on it.

Found out the source of the rattling: old, cracked exhaust hangers.

Supposedly this is the original clutch. PO and his son claims they did not change it during his years of ownership and they were the 2nd and 3rd owner. Maybe it was changed by the dealer after the first owner traded-in/returned the car? Regardless, looks damn good for 197k miles but I put in a new clutch kit and dual mass flywheel anyways, as well as new hydraulics (master and slave cylinders, clutch line) and other clutch job related parts (seals, steel pivot pin, clutch fork, Sachs release bearing, F.A.G. pilot bearing)

Matt also properly installed the GC rear spring height adjusters with reinforcement plates. These are chewed up from not being properly installed over the years. Not sure what I want to do with these because I do need to install longer springs in the rear but I may be installing another set of coilovers in the future.

I was pleased to find that my rear floor was not cracked. Matt and I were amazed that there were no crack even after so many miles. Still, I went ahead and asked Matt reinforced the mounts with Reddish plates. After welding on the plates, he applied primer and underbody coating to prevent any rusting.

I also asked Matt to install the front strut tower reinforcement plates. When doing so, he noticed one of the mounting bolts was starting to pull through.

I also found out through Matt that my CPV is leaking (wasn't too surprised), middle exhaust hangers were cracked, and the engine mounts were worn. Items to address in the future.

Installed fresh interior trim pieces, including a newer center air vent that wasn't broken. I also hooked up the RCA cables that ran to the trunk for a subwoofer (future post).

I took the car out for its first fun "drive" to go check out Julian and Palomar Mountain.
11.4 Route by Zzyzx85, on Flickr

I learned quite a bit about the car on this trip.
First, I need to raise the rear suspension. It hit bumpstops on a few compressions. With GC's 6" rear springs, I am already at the top of the height of the rear height adjusters.
Second, the factory seats are not the most supportive in cornering.
Third, very neutral handling. I have to give credit to the alignment I got. I have never driven this car in the twisties so I was really just testing the waters through the first few corners. I was surprised at how much grip it had.

Great drive. Delicious pie.

I needed more bass. After the drive, it confirmed that I needed more balance in car's audio system.

Rockford Fosgate P300-10. I decided on this after listening to my friend's 12" version of the system, which was way more bass than I needed. After earlier research and asking a friend who had installed car audio systems for a living, I was looking for a 10" sub and this fit the bill. Installation was easy, thanks to the PO for running a RCA cable from the head unit to the trunk. All I had to do was connect the power and do some tuning.

Great work! Love my SDW RTABs. Might be hard to pin point them with all the rear end work you had done, but I'm sure you feel extremely planted back there

yeah, I wished I could (easily and affordably) do the upgrades one at a time to appreciate them but given the situation, I am glad they were done in one go lol.

But it feels incredibly solid back there now.

Ever since I bought car, the low washer fluid light has been on in the instrument cluster. The PO told it was probably the grommet since it leaked out but still sprayed fluid. I tried filling it up and the level light didn't go out, so I figured that was bad as well.

Bought a new grommet/strainer, pump, and fluid level sensor (probably $30 total; might as well do it all, right?)

I finally got some free time to tackle it this holiday weekend. Easy job. Jack the car up, remove front passenger wheel, remove a few screws and the front lower section of the wheel well splash guard comes off, exposing the washer fluid tank bits. I say I got it all done in less than an hour.

Old stuff (forgot to take a picture of the new parts installed...you get the idea though)


After installing the new parts, I filled it up with distilled water, and turned on the car. Light is gone. Pulled back on the wiper lever and it sprayed almost instantly (compared to the slight delay with the old pump.)

Success!
