In another thread on mods I came across the terms WSR and CDV removal.
What do the terms stand for? Thanks.

Seems to me that you wish to move TOO FAST on the Bimmer; two days later you talking WSR and CDV! Well you asked for it

CVD: Is The Clutch Delay Valve restrictor between the clutch slave cylinder and clutch master cylinder = One way restriction. Once installed no matter how quickly you lift your foot off the clutch pedal your flywheel engages at a slow rate but constant. On the positive side? Think sparing the drive train a shock/jolt when clutching at high RPM. On the negative side? You could generate excessive wear on the clutch.

WSR: Is weighted Selector Rod when combined the ultimate result is short shifts, and less clutch journey without hesitation when engaging the gear- Think race cars!

You are the Man!

Update: The car is getting worse. This morning it started to missing at 3000 RPM's. I have to take off very slow or it cuts out. Also, when I put it in neutral and rev the engine I am getting a lot of backfiring. One more day...

Thanks again for your help!

Jim

For now forget about CVD/WRS You have to initiate the very basics in tune ups. spark plugs, filters and then take it from there based on the check engine light codes.

Good luck

Backfires!!! That's unburnt fuel being lit in the exhaust or exhaust manifold - this can seriously damage the Catalytic converter (beyond repair). Seems either the car is running much too rich (faulty signal from 02 sensors/maf is possible) or there is an ignition problem (no/weak spark on some cylinders - faulty pluds or leads) or a misplaced spark (bad ignition timing) - try not to run her more than you have to before you get it sorted.

Thanks guys...

I just dropped the car off to the mechanic. His initial reaction was just what you said Beelz -- plugs and leads. That's where were starting... I will let you know.

I couldn't help but observe how WindowPro's experience shows that, from the seller's standpoint, dealers seem to have defeated "Murphy". In this case, while the car was for sale at the dealer and while being test driven, it runs perfectly (enough to ignite a near-impulse purchase). As soon as it is purchased, stange things occur. used

This is the opposite of every car-selling experience I've had where I get the car perfectly prepared and all-set for someone to buy, but then something new goes wrong on the test drive which I cannot explain, or something expensive goes wrong just before I list it for sale. How do the dealers do it?!? Hmmmm...

True at the end of the day it boils down to where,when, and how you buy the car. As such we cannot blame but ourselves when it comes to buying a GOOD/BAD CAR. With 200.999 miles? all bits are off; exception? a private seller/an honest used car dealer +very low mileage. Reasons?
A. Don't know who had it: maintenance habits,Gas habits, oil changes, driving styles. In windowpro's example he did use carfax; but does it show unreported accidents/floods etc? I am afraid it doesn't.
B. Mileage; that is to say how true/actual the mileage is with all these modern gadgets?!!
C. I think there is a difference between buying a BMW from an authorized BMW dealer (where he puts his reputation on the line when selling a used car)
D.And/or buying it from ABCDEFG Auto Sales on Route 12345 in xyz city.
E. Money? Is the evil in the above equations; or better yet in any equation for that matter. The difference between C&D above can reach $3000 to $7000 in WHAT WE THINK IS SAVING while on some occasions we luck out with a good car, on other occasions we tend to put it back in the car in the form of repeated aggravated assaults on our wallets. That is to say expensive repairs.

BMWs don't come cheap whether you buy them new or used an oil change can range $55-$75 at the dealer/inspection l/ll $350-$450 etc. To put this in a perspective? Buying a BMW (new or used) is very similar to falling in love with a very pretty woman-High maintenance indeed and you know you'll NOT get away with it on a Friday night by spending $3.70 on 10 White Castle Hamburgers--with or without French Fries!!!!

I know EXACTLY what you mean LOL bloody SODS LAW isn't it

I got my last car ready for sale, washed/polished etc. everything worked, then I hit a kerbstone quite hard and bent a track rod end - thank god in the end I managed to trade it for my BMW to a guy who didn't even bother to test drive mine (as it now had a bad habit of pulling to the left).

Gotta feel bad for Windowspro though - Buying a 540i is something that should be a joyeous occasion, all this crap must make him feel like taking it back and buying a lexus or something. Just hope when It's sorted he gets to enjoy it a bit more.

It's called the law of WindowPro -- HAHA.

The car is with the mechanic ... I should be able to pick it up this afternoon ... hopefully. I can't wait to see what she will do past 4500 RPM's.

I will let you know...

Speaking of the law of windowpro, you won't believe what happened last night...

It appears I had a bugular in my house last night! At 2:00 AM my wife and I hear a loud crash (front door slamming open against a dining room chair). I jump up only to find my front door standing wide open!

Evidently, while I was mowing the lawn (at dusk) someone went into my garage (downstairs). At that moment, my wife pulled in from work. Our best guess is that the bugular got trapped in the house -- ran upstairs and hid -- not leaving until we went to bed (6 hours later). CREEPY!

Nothing missing but we are extremely upset ... and ... thankfully alive!

My hope is that a kitchen cabinet shelf or utility room shelf collapsed (didn't check these yet -- had to go to work this morning) and we accidently didn't close the front door good before going to bed. Maybe the wind explains the door ???

So as for the car and my problems ... it is now pretty low on the priority list to say the least. It sure puts things in perspective.
