E60 clutch delay valve - Bimmerfest - BMW Forums

both have them but the e60 is harder to get off. I believe the E39 is just like our e53's all you have to do is get under the car and look at the slave cylinder. If the clutch line threads straight into the slave cylinder - no cdv. If there is about a 3/4 inch long fitting threaded into the slave cylinder that the clutch line is threaded into than there is a cdv. However some people opt to replace their cdv with a special piece that looks just like the cdv but contains no orifice. Far as I am concerned this only made sense if a car is under lease where you wouldn't want removing it to be noticeable.

If you have a cdv all you have to do to delete it is remove it and thread the clutch line right into the slave cylinder. Takes like 10 min.

Above is correct, Zeckhausen and other companies made a "CDV lookalike" without the restrictor inside, so it would look utterly stock but drive perfectly normal, clutch-wise. This was for warrantied vehicles.

Now that the vehicles are well out of warranty and nobody cares anymore, you can unthread the CDV at the slave and rethread the clutch hard line directly into the slave for a free CDV delete.

DO you have to bleed anything?

Actually the e39 M5 is not fitted with a CDV. All other e39's are fitted from the factory with a CDV.

Its prob good practice to bleed the slave when done. I did but I was bleeding brakes at same time

I def think our shipments got stuck in snowman central in Georgia lol, no updates from ups which makes sense as the snow was Tuesday afternoon.

Btw it's so funny I ordered the short shifter after not really buying mods for months, and of course as soon as I make a fun purchase, my CCV rears its last legs and now I will be dropping 300 in parts to fix that lol!

They omitted the "CDV" on ///M models like the ///M3 and ///M5 as far as I know. When I went into Hendrix BMW a couple summers ago to pick up some stuff, one of the SA's asked what I was up to and I told him I was getting rid of that d***n clutch delay valve. He told me that was a bad idea. I said "What? to remove the CDV or for BMW to have put one in there in the first place?" He just smirked.....

My guess is UUC didn't actually ship it. They made a next day air label for mine Thursday morning when they said it was set out to ship that day anyways and then for some reason waited to Friday to actually ship it out. I will have it Monday and I'll install it that day.

I'm looking forward to RB, mcurcio and Greg in Switzerland's reports on installing the SSK and impressions of the performance ..... I continue to be very pleased and have almost forgotten how it shifted pre-CDV delete/SSK ....... I also recommend the fluid changes [tranny/diffs/transfer case] while you are at it, if not already done, adding the LubroMoly antifriction. It may be placebo effect, but drivetrain seems much smoother with the antifriction.

I had my tranny drained and filled with MTL, about 1.5 years ago. No anti friction additive but my gearbox shifts smoother than my wife's legs.

Mcurcio did you call UUC about your shipment? It's been 5 days since I got my order shipped email and the UPS status hasn't changed. I'd just email and double check with them, and perhaps ask if they could take off the signature required.
