It doesn't look like it - my 97 M3 didn't have one either.

[mitchelrl]

Nope, no CDV

[Forkinator]

[99GREENM3]

Why is it a sad day most people take them out ?

[NotUrAvgM]

Was it rather haphazard which years and models got the cdv?

I think the 96+ all got them, but most owners remove them. The next owner buys the car and never has any idea of the what the previous owner had done.

Good point.

I know for a fact my 97 M3 never had one.

Sad day because think about. Im hearing all these things about how awesome it is to take it out and i dont even realize that my CDV is out so i'm excited for some awesome free mod but it's already done. I should be happy lol.

[99MPower]

hahaha..... funny way to think about it

i wish going threw two sets of track pads this month was as free :( but at the same time, I'm happy cuz I was on the track enough to go through two sets of pads... (tomorrow is my 8th day this month, :) and last unfortunately before I leave for iraq :()

Doesn't look like it.

[Forkinator]

My friend is Recon in Iraq. I hope you and everyone there will be safe.

So how can you tell if you do have the CDV on, without looking for the part itself I have a concept of what it does but cant really pin point what the difference would be in terms of having one or not (through driving)?

when you bang a hard fast shift to second or third gear at or near redline in a car equipped with a CDV, it momentarily feels as if your clutch is slipping because the CDV slows full clutch engagement...

Yeah I have a clutch with about 6,000 miles on it and nearly freaked out when I did one of my first full throttle pulls and it slipped into second... I was so confused and freaked out. I thought something was breaking on it then it grabbed and I was still very confused.

Read about this on accident soon after and decided its something I need tog et done. Sure would make you look like an idiot at a drag strip or when showing off. cant imagine how this would effect times.

I had taken out my cdv earlier today and it's a world of a difference. When I was doing my 0-60 runs with the cdv in a few months back, I'd drive 1st up to 6k and shift to second. On second, the tachometer would always stay constant around 4.5-5k rpm, slipping and not exactly going faster, until I let go of the gas.

Gives a smoother ride, amazingly. Was well worth it.

My 98 328i had the stupid thing.

What does a CDV look like? Anyone have a pic, I doubt I have one but I'd like to know.

As stated earlier, it was not present on any cars before 96, so save yourself the trouble.
