Diesel Code Checks, Day by Day
Every Diesel code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many diesel.com would not accept. That is the checkout testing you did not have to sit through yourself.

where this data came from:
25 automated cart runs11 shoppers reporting back1 web search results
11 of these results came from shoppers telling us whether a code worked; the rest come from automated checks and the other sources above. Last confirmed working on . Codes that stop clearing get pulled off this page automatically.
What These Numbers Mean
A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means diesel.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:
- It expired or the store switched it off after it was published.
- It was single-use and had already been redeemed.
- It only covers certain categories, brands or individual products.
- The cart did not reach a minimum spend.
- It is limited to new customers, a first order, or an email sign-up.
- It cannot be combined with an active sale or another code.
- It is tied to a different country, currency or membership.
So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Diesel discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.

Before You Buy at Diesel
What shoppers ask most about Diesel.
›Are promotional codes applicable to all items on Diesel.com?
Promotional discount codes never apply to customized items, personal care products, and select limited-edition capsule collections. These excluded categories are flagged directly on their product pages.
›Can multiple promo codes be stacked on a single online order?
Only one promotional code or discount voucher can be applied per checkout transaction. Customers cannot combine seasonal markdown coupons with sitewide promotional codes.
›How is the UNiDAYS student discount verified during checkout?
Students must authenticate their active enrollment status through UNiDAYS to generate a unique single-use code. This code is tied to the student account and must be entered at checkout.
›Does Diesel offer retroactive price adjustments for items that go on sale?
Diesel does not offer price adjustments if an item goes on sale after purchase. Customers seeking sale prices must return the original item within the return window and repurchase it.
How We Verify Diesel Codes
Nothing goes up here on trust. A Diesel code is collected, applied to a real diesel.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.

The agents keep retesting every Diesel code on this page. No one here vouches for a code they did not watch work. If one slips through expired, take the next on the list. We keep backups.
Help Other Diesel Shoppers
Not every Diesel code reaches us from the store. 5 codes on this page were first submitted by shoppers. They have also sent back 11 checkout results in the last 14 days, telling us which codes worked on a real cart and which came up empty. Wherever a code comes from, it still has to pass the same cart test before it goes up here.

Have a code we missed?
Send it over and the agents will run it through a real diesel.com cart. If it works, it lands here with the test behind it.
Did a code work for you?
Open any Diesel code above and tell us whether it worked. It takes one tap, no sign-up, and a code that keeps failing gets pulled off the page.
