rough idle

Having an issue on cold starts which only occurs on the first start of the day and will not happen thereafter even if the car is left for quite a long time. Essentially the revs bounce between 500 and 1000rpm for a second or two and the engine nearly stalls before the car sorts itself out and it...

Hi all. My M5 has recently developed a very rough idle only when the engine is cold and not fully warm. Initially when it began happening I found that the 2 breather hoses in front of engine bay were completely deteriorated with holes and tears in them (which is common) so I replaced them...

Hey all, I'm perplexed. I had what seemed to be the common issue of rough start and idle after filling up with gas. I searched in the forum and decided to change the charcoal vent canister in the passenger wheel well. I also took the time to change the plugs (didn't break any of the coils!)...

So, I have been having some vanos issues lately. You can find the thread "Vanos Solenoid!!!" and read the back half starting on page 4 of what has been going on. I pulled the DME after tracing the wires in the engine bay checking for any signs of tears, shorts, grounds, open circuits...

I do apologize, this might be a long post. :typing: Well, I'm in a little bit of a jam, literally. The good thing is, its just the solenoid board is jammed inside the vanos unit. The background information: My M5 was idling a little rough, loss in power, 3rd gear pulls would throw it...

Hi folks, I have a surplus of vanos solenoids for sale if anybody needs any. I've sold 4 so far....3 left. Inquiries to . Regards, Stephen

Hey everyone! New Beast owner looking for help (bet that’s the first time you heard that phrase). Here are the symptoms: Car will seemingly start fine when cold, but idles very low (no more than 500rpm, or in other words, the needle usually rests on the top of that first little dot on the...

A few weeks ago I posted to this board regarding a very rough idle in my ’00 M5, along with loss of power and occasional misfires. After much research and help from members of this board, I decided to remove the solenoids and see if they were the culprit. I am pleased to report that after...

I had a burnt clutch incident recently (see here:http://www.m5board.com/vbulletin/e39...-shootout.html ) I had it replaced and I decided to mod the car while at it. I ordered up (among other things) a Jim Conforti Shark Injector from TurnerMotorSport (excellent service BTW). So I waste no time...
