Darkside Developments Reviews 

Slow responce, issues with parts demand but quick to take money.

I mistakenly ordered the wrong part and Ben and Max were kind enough to point this out and offer me the correct part for my car before dispatching the order. It really pays to go to the experts and I was very pleased with their customer service!

An expensive reseller of parts. Arrogant and unprofessional email support.
Did I mention there price's are ludicrous?
If you want diesel performance there are other options available. Call around and you'll be surprised how much money you can save. Remember, expensive reseller. That doesn't mean there parts are better it means they buy them and upsell them to you.

*Update* had an email from darkside ultimately requesting the review to be removed as they see it as unfair. That's absolutely acceptable to request as I also see some things they do as unfair and there welcome to there opinion as I am.
The egr blanks are available else where at an extremely lower price and yes they are also made from the same material. I have both in front of me. I will also play devil's advocate and defend them and say the darkside gaskets are better but the ones provided in the "alternative" website are 100 percent acceptable.
However the price tag isn't.
There prices aren't a myth it's known well inside the diesel performance community that there good at what they do and it's also known to be extremely expensive with alternative options from other bigger players charging less.
The YouTube ads are relentless and I understand there marketing budget after being a customer.
I don't not recommend them I just advocate you do a little research and save the extra money for some more mods!😄
Ordered a sensor that said on the website it was available. After ordering I was told it's out of stock and there would be a delay and it's my fault for not reading and understanding the difference between "available" and "in stock" it's actually funny the snotty reply I received.
The item I purchased before the sensor was an egr delete kit and the instructions were just awful. Really lazy.
Had to email back and forth to confirm something simple but needed to check and who better to ask after paying just a premium?!? Maybe more time on the small details would at least justify the silly price. Isn't like it's packed well either so I'm struggling to figure out where the value is.
I guess I'm paying for the YouTube sponsored videos😄

**Update after reply**
I placed the 1st order unaware of the cost and felt foolish. The second order was for a customer whom needed a sensor asap. I ordered the sensor as you listed it as AVAILABLE and I payed around £7 in delivery for Next day. You then emailed me saying it isn't in stock and even admitted in a later email you were rude due to high email volumes from customer. (Can't imagine why...)
So I politely requested a refund on the delivery as the customer shared the same opinion as me.
You completely declined to refund the postage, were rude and I left it at that. Weeks later I came here to share my experience and opinion.
Hope this explains the 2 orders.

Also worth mentioning I said the exhaust gaskets were a better quality and this may be true but the one provided from dark side is leaking. It's the gasket that goes with the plate to the intake manifold (egr delete)
The gasket has failed a smoke test.
I don't think dark side are in any position to be telling someone that other businesses upsell when there doing something no one else is. The numbers are the facts and if you bother checking you'll not be one of there "happy customer"🙊

Darkside do you in house manufacturer the egr delete kits ?
Very interesting question with regards to the upsell percentage.

I have made two purchases from Darkside and am very happy with the products both times. Its the only place I can purchase this oil for my car and what a difference it makes. My 24 year old PD engine purrs with this oil. I certainly want to try the intercooler kit as my OE part has the classic issues associated with this engine. Injector clamps and a new turbo too when I am confident I have found the right garage to do the work. Recently had terrible difficulty finding a garage who understood that the right hand engine mount needs removing during timing belt replacement and therefore stretch bolt replacement!

Good company to deal with. I have had bad experiences in the past with other companies with sorting my clutch out. I needed a clutch alignment tool for my car. I was contacted the same day with the details of the required part. The new clutch was fitted this week and the tool worked perfectly, a really good fit. I couldn't be more happy. Great experience.

Brilliant company to deal with. From first point of contact they were very helpful ensuring I ordered the right part. I bought a front mount intercooler for my bmw from them after having fitment issues with one from another company. Darkside ensured there one was a bespoke item to them and would fit using my stock pipework. They were correct. Fitted in no problem at all. Looks ace and is very, very well made. Super happy with the guys down at dark side and I’ll continue to use them for any performance parts in the future! On top of all of this my part was with me in less than 24hrs!

Top tier company cannot fault them one hit
From start to finish with my build they have helped with what products my vehicle would need/fit to just genuine help & advice
Should be proud of their customer service

Used these company a few times now, I needed a clutch for my car and had needed to email reg to check I was ordering the right one, after the first one come back as a 5 speed I replied and said it's a 6 speed, "TONY" Was more then helpful and sent me a link to click to buy the right part and also adviced me I did not need a fly wheel saving me best part of £400 plus, so honest as well ! Will be ordering some upgrades for the car next year and this will be my only port of call

Friendly staff, great service by people that know what they are doing, very happy thanks.

I contacted this company for advice on a family members car, from the very first email (from Danny and then Harry) I got a top level of service and advice. Even before I had made a purchase they gave me advice of what the issue could be before I committed to making a purchase.
Unfortunately for us the car ended up needing a head gasket, there was three different variations for the car and Darkside allow us to order all three and return the ones we didn’t use.
They also advised that the likely failure was either due to water pump or head lift as the car had been mapped and this particular model suffers from this and advised a remedy for this also.
I ordered quite late in a Thursday and emailed to ask for a next day delivery. The order was packed and send and we received it by courier the following day. The returns and refund process was easy and I received my refund quickly.
I would 100% recommend this company as they could have sold me all sorts of parts to remedy the issue with the car but they took the extra time to help with diagnosis to make sure we got it right first time.
The car is now up and running perfectly.
Thank you Darkside and keep up the amazing service.

You are a truly great company!! You are very responsive and concerned about your customers! It's so rare! Congratulations to all of you! And thank you very much !

10/10

Absolutely flawless these guys, messaged them and they replied fast, also the parts I got from them have been nothing but amazing top quality parts and really easy and straight forward to fit

I can't stress enough the service is 11/10 l ordered a inlet pipe for my car found out it was the wrong one l emailed them and it took not even 20 mins for them to get back to me they found the right part I needed as I was struggling and the problem was resolved within a hour maximum, too whoever Ben is at dark side developments u helped me so much and allowed me to swap over the product to the right one I needed thank you guys so much top class customer service and top class support, thank you guys

I ordered the wrong part and had to contact customer support, they almost immediately answered and swapped the correct part to my order. Will be doing business with them in the future

I recently took my T5 Transporter to Darkside as a returning customer.

Their workshop experience and customer communication is top notch.

Helpful advice, great communication keeping you informed from the moment your order is placed and highly skilled mechanics/technicians.

Booking in with Darkside and travelling from the Midlands is always worthwhile for the professional service, and being a fussy mofo the care taken to my pride and joy.

Credit to Darkside as a whole, professional and reliable.

I had been trying to source very specific brake pads for some time and kept getting met with the same response from other vendors. 4 - 6 weeks lead time, which is fine I get parts have lead times that vendors can't control. The difference here is that Ben from DSD went over and above to not only source the parts for me but worked with the supplier directly to reduce the lead time down. Parts came a week earlier than expected. And I'm a first time customer for DSD so no favouritism here just good honest customer service.

I recently had the pleasure of working with Darkside Developments, and I couldn't be more impressed with their service. They supplied me with high-quality parts, which I installed before visiting their HQ. Once there, their team carried out a custom remap and coding on both my VW Tiguan and Touareg—all within a single day.
From start to finish, the professionalism of the team was outstanding. They kept me informed throughout the entire process, ensuring I understood every step. A special shoutout to Tony and William, whose exceptional customer service made the experience even better. Their expertise and attention to detail truly set Darkside Developments apart.
If you're looking for top-tier automotive solutions with impeccable customer service, I highly recommend Darkside Developments.

Replied quickly to a technical question I had about a potential order I needed very quickly (my fault), knew about some extra seals I could install at the same time and delivered very quickly. Great guys!

Had booked my Audi A4 Avant B9 TDI V6 272.S Line Quattro S/A for Mon 7th April 2035. For a Stage 1 bespoke Dyno Tune with V Max delete . Plus a Stage 3 gearbox Tune .
I had used them before in the past on another A4 TDI . It was really good to see their expertise and performance gains was still of a very high standard . They might not be the cheapest but they are definitely one of the best .
Very highly recommended
