Can you do the post mortem reply to the link I provided above? Trying to consolidate.

No problem. I will call AutoHaus on Monday - they are local to me - and get a replacement.

Hello everyone, my name is Daniel and I'm with URO Parts. We definitely appreciate the valuable feedback and keen observations made in these window regulator threads! Yewzer B Lewzer is 100% correct about one of the biggest window regulator design challenges: the cable jumps off the pulley upon release of tension when the regulator is in the fully up position. Our engineers agree that this is one of the key causes for failure in the system and is precisely why we added ball bearings to the pulleys. Bearings allow the cables to be substantially tighter than OEM, reducing cable slack without increasing drag. As Yewzer observed, URO Premium regulators also have a smaller gap between the pulley and the steel rail and the groove in the pulley is deeper to further resist cable jump.

In addition, we routinely pull samples from production runs and test them in actual car doors (many have gone 400,000+ open/close cycles and counting) to observe wear, identify potential issues, and confirm manufacturing is to specification. We have had great feedback from some of our distributors and certainly welcome real-world feedback from e46fanatic members and other end users. Our goal was to surpass OEM performance and durability and though achieving a failure rate of zero isn't realistic due to manufacturing anomalies we're very pleased with a warranty rate of far less than 0.5% thus far.

Chibo, if you're having any trouble receiving your replacement, please let us know so we can send you one directly.

Hey, now that's customer service.

AutohausAz is local to me - just arranged a will-call pickup on a new regulator for today/tomorrow.

uropartsman, I'd like to say thank you for being the only company that has taken this issue seriously enough to release an updated design to address the high failure rates of these regulators, and standing behind it with a lifetime warranty

Can you please let us know how is this addressed in your premium design (I have 4 pending regulators to replace with the same part broken)

Unfortunately mine decided to strip the gear teeth on the motor assembly after it jammed.


Here is the right side regulator, which I have not yet installed. You can see there is no clearance between the spool and metal frame.


Somehow the regulator managed to clearance itself.

@paraklas - We have never encountered the window guide breaking as in your picture. This is not a common failure.

@Chibo - Your pictures don't show it, but my guess is that the cable is off the pulley. That is the initial cause of the failure just as previously described. Once the cable comes off the pulley it will get wound up in the spool as shown in your photo. If you PM me your address I will send you a new motor for free.

The goal of the URO Premium regulator is to keep the cable from coming off the pulley while simultaneously reducing the resistance through the use of ball bearings.

You guys are awesome I ordered a used motor off eBay for $25 a couple hours ago; I greatly appreciate the gesture!

Just got back from picking up my replacement from AutohausAz - now to wait for the motor to arrive.

Feel free to post that on my thread too. Maybe Uro can help us find a solution to the sticking glass?

With sedans it is actually common, the extra stress on the cable due to friction on the door frame guides goes to the weakest point which is that thin piece of plastic that BMW (and Mercedes) thought it would hold fine. And I'm wondering since you say that you added even more tension on the cable, if it will cause that clip to fail prematurely in conditions where there is excessive resistance from the glass going down/up - not everyone cleans and lubricates their window guides. I would buy in a heartbeat a regulator with metal or at least reinforced slider clips (and the ball bearings that you already offer ).

I applied this fix on a couple of regulators that were saved (owners didn't try to roll the window at all and steel cable remained intact) and it is holding fine after a couple of years (picture taken 30/06/2008):

^ That's exactly the problem. The sliding clip brakes because the glass sticks to the seals.

What lubricant do I need for the window glides. I bought the URO premium for my XI. Passenger door started making noises.
