UNIQUE APPROACH
It's by reprogramming the very basis of the controller itself that we achieve the results we get - just as the manufacturers themselves work.

GREAT PERFORMANCE
By starting from scratch for each calibration, OEM+ achieves a very different level of performance and drivability. It's never just about winding up the peak power.

PEACE OF MIND
We are uniquely positioned to tap into a vast knowledge base and resources network in our development.

MATCHED TO HARDWARE
No other brand can offer you such a comprehensive 'full-car' tuning solution. Our Performance Parts range is the most complete on the market, all matched perfectly to the OEM+ software.

UPGRADES FOR LIFE
Free upgrades on your car for as long as you own it. Start with OEM+ Stage 1, then we will give you Stage 2 and even Stage 3 Performance Software for free!

RETURN TO STOCK
Should you ever want to return your car to standard, the OEM+ system has the facility to return your ECU to 'True Stock', the exact state it was in prior to installation of OEM+ tuning.

RacingLine has been developing high quality performance hardware parts for race and road cars for nearly two decades - firmly establishing ourselves as the hardware brand of choice for Volkswagen Group vehicles. But we aren’t stopping there.

We have been working flat out over the past two years to develop our OEM+ Performance Software. We believe it to be simply the best ECU Software Upgrades and TCU DSG Transmission Software in the market, conceived from a very different approach. By bringing together a full suite of carefully developed software, all matched to work in perfect harmony with our ever-growing range of hardware, we truly believe that RacingLine Performance can offer customers the most complete range of upgrades for their VWG car.

OEM+ TCU Dynamic Software & Tuning is simply an essential upgrade to get the most out of any modified DSG car.

Several years of road and track development have given us the smartest transmission software on the market: by continually feeding the engine ECU’s torque demands through to the gearbox’s controller, the system dynamically calculates and adjusts the DSG’s variable clutch pressures to suit whatever your power output is.

Meaning that just one RacingLine TCU software upgrade will serve your car from standard, through Stage 1, right up to Stage 3 and beyond. So unlike some, there's no need for a new TCU calibration each time you increase your car’s performance.

Our engineers reprogram the gearbox's calibration inside the TCU (Transmission Control Unit). This allows the transmission to maintain higher torque levels through our dynamic clutch pressure strategy, right up to a mighty 19 bar pressure. The result? Shifts are even faster, giving harder acceleration through the gears, whatever level of performance your car has - up to and beyond Stage 3.

Meanwhile, the driving mode strategy itself is optimised to suit higher power levels, giving a more natural gear selection profile. Flick the car over to manual, and at last you'll have true gear control at your fingertips - no auto-upshift*, no kick down until you command it (or drop back to D/S modes).
Not only that, launch control will get you off the line quicker through allowing more boost at launch and increased launch RPM, combined with a less intrusive traction control in launch mode.

* auto-upshift disable not available on certain gearbox codes

Good for routine maintenance
The Eufy is a huge time saver, but the one annoying thing is continuously needing parts to replace it. This is where this purchase comes in - these parts fit just like the original parts, and take just seconds to install. They seem to be just as durable and functional. The brushes sweep corners well, and the filters keep the machine quiet while still pulliing in all of the dust. It's a great value to buy several at a time since they need to be replaced on a regular basis. Highly recommend!

Great set of parts for the C10
I have 3 dogs and 3 cats so my robot vacuums get run multiple times a day and need maintenance performed more frequently as a result, plus I go through a LOT of the bags. (Labradors… IYKYK.) These parts appeared identical to the originals and all fit perfectly into my vacuum. The filters and brushes were all excellent quality and the roller bar was possibly a little better than the original. The dust bags feel thinner than the original but I haven’t had any issues with them - they fit into the compartment properly and haven’t torn or broken open. It’s a good kit and I think a pretty good deal, I would definitely get it again.

Perfect!
Everything in the set feels high quality and fits my Robo perfectly. Installation was simple, and the pieces line up just like the original hardware. You get a lot for what you pay, so it feels like a really solid value at this price point.

Pretty great set for the price! HOWEVER, the rotary brush doesn't fit.
This is a nice little set of replacement items for your C10 for the price. It's always good to have extra bags, brushes, and filters...especially if you live with multiple animals on a very dusty farm like I do! The filters, bags, and front brushes fit perfectly in Tilly (my Eufy C10), however the main vacuum rotary brush was too short and did not fit. You can see from my photos, I've compared it to the original brush for the vacuum and it is too short and the end fittings do not match up either. This is the only part of the set that didn't work for my vacuum. The rest of the set is acceptable quality for the price. The reason I gave this set 4 stars instead of 3 is because I actually PREFER these front brushes over the originals because they WORK BETTER than the originals. If the issue with the fit of the rotary brush is addressed, this would be a 5 star set of C10 replacement parts.

Perfect combo replacement parts.
These replacement parts fit my Eufy C10 without any issues and were easy to install. Everything snapped into place just like the original components, and I did not need any tools or adjustments. It was a quick refresh that had the vacuum back to normal cleaning right away. The main brush feels sturdy and does a good job picking up debris without getting tangled too quickly. The side brushes spin smoothly and reach edges and corners well. I also noticed that the filters fit securely and do not feel flimsy, which helps maintain suction and keeps fine dust contained. The dust bags are well made and install cleanly without gaps or leaks. After replacing the parts, the vacuum runs quietly and cleans more efficiently, especially on hard floors and along baseboards. It feels like routine maintenance that actually makes a noticeable difference in performance rather than just a cosmetic swap. Overall, this is a solid replacement kit that matches the original parts well. It is a convenient way to keep the robot vacuum running smoothly and is a good option if you want reliable performance without hassle.
