Broken Quarq Dzero power meter
Discussion
Bought a Quarq Dzero at the end of 2019 after recommendations on here due to accuracy and reliability compared to other makes.
As of the weekend its now dead
connects fine via BLE and reports cadence but power stays at zero. Calibration (zero offset) reports a crazy 32000 figure. Done the reset and changed batteries (not Duracell with the bitter coating). So I expect that's the end of that. £475 down the drain after less than 3 years of use, most of which has been on the trainer.
SRAM tech support have been pretty useless, just said to try the reset and check some settings in the AXS app which were all fine. It's out of warranty so I expect they don't really want to know. no mention of a discount off a new unit or anything like that.
Now what's really annoying is that I can't even get a new spider as they have changed the design to the new "DUB" standard and the offset/chainline is different so the Quark cranks are useless too despite having the correct 8 bolt spider interface.
Anyone else had any experience of SRAM/Quarq support or have any other avenues to try?
It was a big chunk of cash for me to spend so it's really got me quite down tbh. On top of all the energy cost stuff and general doom and gloom. Is <3 years an acceptable lifespan for something like this?

Sorry to hear that, a total PITA. The reason I went for Quarq (I have them on 3 bikes) was the security of the warranty as I had issues previously with a P2M which had to be returned to Germany. All mine have been virtually faultless with the oldest now over 5 years old (Quarq Dfour GXP with DA 9000 chainrings) although this oldest one has chewed through the last two batteries rather quickly, so hoping its no the sign of the end.As of the weekend its now dead

Anyway, I would say 3 years is unacceptable for a relatively high value item to break and would contact them again about your experience. I know its a 2 year warranty but 3 years isn't good enough.
Thanks will shoot them another email.
It's been great until now, but it quit about 2 hours into a 120 mile ride at the weekend which put a bit of a downer on an otherwise great day out in the saddle. I noticed that the power had got stuck at 1500w (and I definitely wasn't doing 1500w!) for a minute or two then just went to zero. Have found posts on other forums with very similar issues but people never update threads with the outcome or cause of the problem.

Retailer was semi helpful and contacted SRAM for me but SRAM still refusing to do anything whatsoever, not even a discount on a new unit.
Looking around forums. ebay etc. there seem to be quite a few cases of this error happening (cadence works but no power) with the Dzero spiders.
Will be making sure I never purchase another SRAM/Rockshox/Quarq product in my lifetime.
Looks like the bare cranks go for a decent amount so will be sticking them on Ebay and replacing with a shimano HTII chainset so I can get a cheap single sided 105 crank based PM. At least if that breaks it's only £200 rather than £500. Hoping to order a new bike soon that will have an ultegra chainset so should be able to swap it between bikes easily enough.
Considered the Favero Assioma pedals but they work out more expensive than swapping the entire chainset over, and I'm not a fan of Look cleats.

Pretty sure you can get the assioma in a shimano version now? Might still be your best option as I think the single sided crank arm (stages, 4iii) are not without their own issues! I'd say you've been unlucky with your quarq rather than it being a bad product....
Cranks have got decent resale value as they are very light and you can't buy them any more!

Yes had a read about the Shimano option for the pedals as I could use the bodies from my existing pedals but a couple of things put me off- the 11mm increased width per pedal (some say it's not an issue but I don't want to drop the best part of £500 again to find out my knees don't like it) and the fact they had to go to a nylon bushing instead of a proper bearing, and they're £50 to replace as you have to buy the whole adaptor cartridge.
The Quarq has been great until now but it's more the attitude/lack of support by SRAM that has put me off.

I've had two Quarq DZeros die on me, both coincided with a dropped chain. When I was Googling, I read the GXP BB chainsets were vulnerable to dying with dropped chains, which is what I have.
Switched to Favero pedals after recommendations from other club riders and they've been perfect.
Quarq/SRAM were no help as I was out of warranty. Bob at Cyclepowermeters.com tried to help but there was a long lead times on parts.

I don't get this attitude from companies. I had reason to use the crash replacement from Canyon and Bell. Canyon were brilliant, very understanding, efficient and very cost effective. No doubt I'd be looking first at Canyon for my next bike. Bell were useless, awkward, unhelpful and directed me elsewhere. So I did and bought my new helmet form MET. I'd have thought Bell would have preferred some money and a glowing review like Canyon has received... Trif said:

I'd definitely think twice about it, a few bits on the MTB were badly put together (chain on backwards, BB ridiculously tight so had to use a breaker bar after 400km to replace it..) Customer services were less than helpfulukbabz said:

Customer services were less than helpfulI had similar issues with the 'limits' power meter which was on kickstarter a few years back it worked ok at the start then gave really wack readings.

SRAM are useless and is the one brand I wouldn't touch again with a barge poll, their brake master cylinders contained a plastic that swelled when in prolonged contact with brake fluid and seized in the cylinder leading to the lever not returning yet they offered no recall even though it's such a dangerous manufacturer defect and serious accidents have occurred.

I don't understand why manufacturers still struggle with hydraulic disc brakes? I'm currently in the process of getting a warranty replacement on a Shimano GRX brake caliper, this is the second one I've had leak. No spare parts available, just replace the whole lot. Thankfully Ribble have been very helpful both times. offering to pay for the return postage and make a contribution to fitting costs at a LBS (although I'll fit it myself anyway). Yet I've got two sets of Hope brakes on other bikes that just work. One set is 18 years old and they still work fine, only work they have had is a change of seals about 7 years ago. And I can still get all the bits for them at a reasonable price.If/when the GRX brakes fail again they will be getting replaced with Hope RX4's.

Interesting. Which flavour of GRX?If/when the GRX brakes fail again they will be getting replaced with Hope RX4's.
The original equipment GRX 400 callipers started leaking fluid out the piston bores on to the pads, on my Boardman ADV8.9
After nearly 3 months without the bike last summer, Halfords finally sorted themselves out and gave me 810 callipers as replacements. Haven’t done anything like the same mileage this year for various reasons so don’t know how long I’ll expect these ones to last.
