Got her wet and dirty

Had not driven her for 8 days so hopefully a good drive keeps the battery healthy. Comfort access was acting a little weird when I first tried to get in. Worked as normal at the end of the drive. Car has seen rain.

Nice! Water pump and thermostat just for the fun of it or did you notice issues? (What mileage btw?).
Did the TAs a few weeks ago probably watching the same DIY... Some of the wire connectors was quite tricky/hard to losen, and yes the plenum/hoses needed some luck to get back in place without too much hazzle...

Looking great! Sometimes after sitting for a while, I need to physically lift the door handle to wake the car/comfort access up. Is this what you experienced? I wonder if it's a sleep mode.

74k on an 2008, family car, daily driven. Its been a rough year. I'm around that year and mileage where everything goes wrong.

Alternator, misfires, it was due so replaced all sparks (last done at 34k), continued to code, isolated to bad ignition coil.

More recently, Ive been dealing with a misfire, thermostat, and occasional bank 1 error which would put the car into limp mode at idle for about 4 months. Im in Texas generally 75 degree weather right now, car would take about 15 minutes to get even close to operating temp, never reaching 210. After replacing the thermostat, maybe 3-5 and hits 210 and stays there.

Ive avoided doing the work.

Everything under the wiring harness and on the car in general is "brittle" given its age so I was pretty careful but couldn't avoid breaking the suspension slot for the two connections under the wiring harness. I address the brittle issue by only moving/removing and flexing parts on the car as little as possible. I had only 2 to 3 inches of play with the harness, nothing like what they were working with in that video, one connection I couldnt break loose and knew I would crack it if I forced it anymore. The plenum went back in a little too easy

Maybe I should double check my work. It looks like it is on

and here are the videos I used.

Sounds like challenge when things get brittle! Funny, neither of the two DIY thread I followed did the harness similar, and I ended up doing it slightly different still, guess we all find our ways.
Yeah sounds like you had your share, but managed it quite well so far - great work! Daily mine too but between garages, and 2011 with 45k miles so extremely solid so far. After almost 6y ownership Im starting to enjoy doing some of the stuff myself although limited work area. Dreaming of a garage with tools...

Cheers

Yes, believe that's what I experienced. So normal maybe.

Hmm, I'm in Nor Cal on BE bearings with 10w-60 Castrol and the car takes probably about 10-13 miles ( 20 minutes, mostly highway?) to warm up. Even then it basically just gets to 200 degrees and sits there and won't get to 210 unless I start driving above 6k RPM or sit in traffic where it idles. If I just let it idle ( I know it's not good) then it comes up to temp much faster. If I beat on it on the back roads I think it gets to like 230 or so.

I wonder if I need the thermostat changed? Not quite sure what's normal.

My N55 M2 warms up in 6-7 miles on 0w-30.

Not true, I had a similar issue last winter. My oil temps wouldn't reach even 200 degrees on my 40 min drive to work. Replaced my thermostat and it resolved the issue.

Cept it does.... If the T-stat is stuck (broken) open, it will take forever to warm the car up to operating temp. My m3 takes about 3 miles to be at operating temp.

Doesn’t matter what perceived results people notice. A coolant only thermostat doesn’t have an affect on motor oil temperature. Water temp and oil temp aren’t integrated with one another. you guys are implying a coolant thermostat is preventing the motor oil from heating up. Or you’re implying a coolant thermostat is not properly displaying the correct motor oil temp even tho it has no contact with the motor oil so how would it know?

No, the thermostat is stuck open and is flowing coolant faster than it should, keeping the engine block + cylinder temps cooler, and thus making it take longer to heat up the oil.

A proper working thermostat limits the flow of the coolant to the block when it’s not needed to allow oil to flow better / reach operating temp, and open up more when the engine needs cooling.

Mine warms up in 6-7 mins or around 3 miles and it shouldn’t take any longer.

Alright... well, where can I get a new thermostat at a reasonable price?

Are those OEM CF splitters and CF front grille frame ? Somehow they look painted over or is it just the light that day ?

I'm around 6-8 miles and 10-12 minutes to get to 200F also. Seems longer than my S54 to get up to temp, but the gauge wakes up (gets to ~140) quicker.

OEM splitters, though I need to reinstall the driver side one as scraped the bottom and it pulled it slightly so it doesn't sit as flush as it should where the 3M tape is.

The grill was on when I bought the car, it's a plastic matte black. Most are gloss black. It's not carbon, but the matte look can be more gray depending on lighting. I don't plan to change it and wrapped the side gill with matte black to match. I will also wrap the hood intake grill with matte black when I find the time.

Well, thats one theory. I've also heard that if the thermostat is stuck open that water doesn't stay in the block long enough to pick up heat (quench), so the motor can still overheat even though its getting plenty of coolant flow.
