Came down and felt my steering wheel rattling with certain combinations of throttle / speed (got real bad around 3250-3500 RPM). I had the original steering rack swapped out for a remanned Z3 unit just last week and was deathly afraid that I had already busted it. Stopped by the gas station to have a look and noticed that my Dad had gotten my strut bar painted black. A nice surprise, but didn't exactly help explain my rattle. As I'm heading to Waterford Hills for a track day on Thursday, I was pretty keen to get this figured out. Pulled into the garage and after searching high and low for a problem with the rack, tie rods, suspension, wheels / tires, or anything that I had just had adjusted, I noticed the noise I had been hearing was coming from closer to the firewall than anywhere down low on the car. After a bit of searching we noticed a rather odd looking part sitting directly on the steering shaft. After some more searching via Google images and a quick read through of the DASC installation guide forwarded to me by the great Mr. Jim Goodroe, we figured out it's the old DISA valve that had been removed from the intake system but left in the car. From the DASC installation guide: "Get the DISA valve from your earlier disassembly and connect it to its electrical connector in the engine harness. Using one or two zip ties provided, secure the valve to the dipstick tube below the elbow so that the valve does not interfere with any engine components and so that the valve flapper still is free to operate. This is to keep your ECU happy (And your “Check Engine” light off)." Long story short, I think I broke a zip tie and not my new rack. Track day saved.

Part it out immediately... and I'll take the DASC off you hands at no charge, I'll even pay your shipping fees. No worries, you can thank me later. Seriously, glad that you found the issue so quickly and with a very inexpensive fix (a couple of zip-ties!)! __________________ James 95 active w/leather interior and sport interior conversion, Vaders, full M-Tech exterior conversion.

I don't want to run the risk of throwing a CEL before Thursday so I think it's zip ties for the time being... | | | 05-06-2014, 06:22 PM | #6 | Senior Member Join Date: Oct 2008 Location: NJ Posts: 106 | Its just a 10 watt 100 ohm resistor with an inline fuse if you want. If hanging the DISA works, I wouldn't worry about it. __________________ Mods: DASC, NickG Stage II DME software, 30# injectors, RRFPR removed, DISA Simulator, Secondary Air Pump relocated, bypass cooling hose removed, Fogged airbox, Bosch silver sparkplugs (F6DSR), Magnecore sparkplug wires (KV85), SeattleCircuit mpg adjuster circuit; Textar CeramicFusion brake pads; S/E/M auto trans selector with Euro software TCU; Royal Purple trans (MaxATF) & diff fluids; Koni FSD (F&R); Rogue RSMs; Strong Strut; Butt Strut; Bridgestone Fuzion ZR1 225/50/16 on Style 42's; hardtop; Footwell lighting; Interior lighting On/Off switchable; Euro intermittent wipers; Padded LeatherZ arm rests; Sisa Design Cabrio Wind Deflector; | | | 06-11-2014, 05:19 PM | #7 | Member Join Date: Mar 2014 Location: Detroit, MI Posts: 70 | Quote: Originally Posted by wolferj No, you are completely wrong.

Long story short, track day was more brief than anticipated... Working on the motor now and will be making a plan once we get the head off... Wolferj, you may just get your wish with the DASC! | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
