Our M5 Journey Begins

Post by Fanclutchnut »

It took a while, but we wanted to say hello to this great community. We’re Chris and Brody, a father/son team in Tarrytown, NY. Back in January, I (Chris) was doing my usual trolling for cool Germans on Craigslist, OfferUp and boards. I came across Funfunfer’s listing and sent it over to the boy and my advisory board (brother, brother in law and good friend). It received unanimous support. I was a lurker, so my friend Dave (who’s building a e28 535i) offered to reach out to Funfunfer as my account was taking some time to get approved.

Funfunfer was really responsive and great to work with. He seemed to be happy with where the car was headed and our plans for it. Ironically, we even have some common acquaintances. It took a bit to get everything sorted out, but the car was purchased delivered to us second week of March. That worked to our benefit as we had time to get our garage sorted out. You should hear the video of it coming up our block. It’s hilarious, we were cheering.

A bit about us. I’ve been working on cars since I started driving, mostly because I couldn’t afford to have others do it for me. My first German was a 84 318i Bronzit Beige MT in the mid 90s. One of the first jobs I did on the streets of the Bronx was a fan clutch (hence the name). Since then, I’ve owned and/or worked on 80s-2010s BMW, Audi, Porsche and Volkswagens.

Brody is 15 and has been a car guy since diapers. I knew it when I did the seasonal summer wheel swap on my 02 Volkswagen GTI 337. He waddled out to the driveway and lowered down to the BBS RCs and “ohhhhed”. He was a year and a half old. Since then, he’s been around and gotten rides in some cool cars, e30 M3, 944 Turbo, 930, S3, and MK1 GTI to name a few. An E28 M5 is pretty much his dream project car. He’s been really great so far prepping the garage and gathering information. His enthusiasm gives me a lot of energy!

One of the things that made the car attractive to us is that Funfunfer included many of the parts that will be needed to deal with the known issues. He also included a ton of PO documentation, printed reference manuals that are available online and digests from bmwcca. We’ve already begun to sort though the included parts and materials. We’re still building our plan, but we think the aim is to bring it back to the state of a well enjoyed and maintained driver.

Well, here’s some pic of the journey thus far. We hope to document this as best possible to give back to the community in any way that we can. A very special thank you and best of luck to Funfunfer.

Thanks for the warm welcome everyone! We have some progress to report.

The car was running when shipped, cranked but wouldn’t turn over on delivery. Filled with some gas, checked for good spark, checked CPS, replaced the reference due to a bad connector, checked fuel and main relays. Everything looked ok. The car would turn over after sitting for a few days or yanking the fuel relay very briefly and respond to throttle.

Suspecting flooding due to a clogged return line. We’ll start with the curved hose coming off the front of the fuel rail. Could be the regulator too?

We’ve gone through the parts and right now it looks like we need to source a cat section and natur carpet, mtechnic wheel and shift knob. I’m sure there will be more as we go.

More pics this weekend!

Had some quality garage time today! After reading a few threads about similar no start, has spark, has fuel but rich, I came to the conclusion that I’d check the FPR and the ICV. We checked the return line by blowing through the elbow hose at the front of the fuel rail. It was clear and the hose was in good condition. Next we checked the vacuum line for fuel. No fuel, diaphragm probably ok.

Next up was the ICV, I read some conflicting things about when it would be energized. Turns out it only gets power when the car is cranking or running. I jumped out terminals 87 and 30 of the fuel relay. The pumps ran nicely but the valve didn’t buzz checking with our long screwdriver stethoscope. I recall seeing a thread that showed corrosion at the connector.

We disassembled the thermostat housing to get access to the connector. As soon as it was unlplugged, we could see green corrosion on one terminal. Brody cleaned all of the connectors up with some qtips and deoxit spray.

Next we tested the 1&3/2&3 valve terminals for proper resistance, 40 and 20 ohms respectively. Looked good. We reconnected the plugs and ran the fuel pump relay jumper test again. Our ICV is now buzzing! Lastly, we reinstalled the coolant hoses.

Hopped in the car, cranked it and within 2 revolutions, it started. Idle was smooth and it responded to throttle input. The exhaust is still open at the header, so we didn’t let it run for long in the garage. We were very pleased with our progress today.

I order a bunch of fasteners, clamps and a gasket from our local BMW of Westchester to get the airbox reinstalled next. There is one part that goes inside the airbox that is NLA. It doesn’t look like it will affect assembly though

The AFM/diagnostic plug bracket that had the rubber isolation stud mount needs to be repaired. We’re going to try some epoxy tonight.

I’m doing research now for the parts we need soon.
Wiring harness repair(cloth tape, heat shrink tubing, best type of solder)
Natur Carpet/padding/sound deadening replacement
Cat section for the exhaust
One outer rear bumper shock

Here’s her current state. We fitted the NA headlights, grilles and tail lights.

Busy day for the parts dept here. Procured a Natur carpet and cat exhaust section for her today. Airbox AFM gasket should be coming from Germany this week as well. Did some research on cloth tape, shrink wrap and solder for the harness repairs. Fortunately Brody’s been soldering since he was 4 so he’s well heeled for the job :D
