With our Gen 3 Electronic Wastegate Actuator Extension Harness, you no longer need the turbo on the engine to check and adjust the wastegate voltage. You can set the wastegate voltage on your new turbo/actuator outside of the car before installing turbo. How does it work?

Connect the CTS Wastegate Actuator Extension Harness to the electrical connector on the vehicle.
Connect the other end of the extension harness to the turbo on your workbench.
Turn on ignition but do not start engine.
You can now start up your computer and VCDS/OBD11 on the same workbench and calibrate/troubleshoot the wastegate voltage at your convenience.

Features:

Calibrating wastegate voltage is easier without turbo installed
Troubleshooting wastegate operation (fix P2563, P00AF and P0045 codes)
Convenience - save time and money
Ease of adjustment - no need to dive under the car to set correct voltage

Just wanted to share some love to Harry's euro and their team! Bought parts for my r32 and gti, they never disappoint. Love being part of the euro community in an ever so dominant jdm culture in New Zealand. Looking forward to bringing an rs3 in for tuning :)

Greg Davies

Great to have parts for my Range Rover so readily available in nz. Fast delivery and awesome quality products. Thanks guys!

Nick Ko

I took my BMW to get the downpipe installed. Harry's Euro has done an excellent job. I'm very satisfied with the quality of their work. The staffs are very nice. Highly recommended. 10/10

Sebastian Ramirez

I've been a loyal customer of Harry's Euro since 2017, and I can confidently say Scott and his team are the best in the game. Not only do they consistently offer the best prices, but the service is always top-notch. Scott is honest, transparent, and always takes the time to explain what’s going on with my car. Whether it's routine maintenance, unexpected repairs, or upgrades, I always know my car is in the best hands. Highly recommend to anyone looking for a reliable, expert mechanic!

Andrew Atkinson

Used Harry's Euro for years owning a Mk6R and now a Mk5 R32. Amazing service and delivery! R32 kit arrived today with some extra goodies! Pleasure to deal with the team!

Mark Barber

Hands down the best Euro shop in Auckland. They've looked after 2 builds of mine, and the parts, service and expertise has been top notch.

Marc Graham

Harry's Euros delivered platinum service from start to finish. The quality of the products is excellent, and the install experience was smooth and professional. If you want a lower cost acceleration boost ask Scott about a Pedal Box! Huge difference and very simple to use.

Quinn Ashby

Got some basic servicing and a Stage 2 transmission tune done today to match the ECU tune. The team was really helpful with information, communication via email, fit me in quickly, and offered fair, industry standard pricing for a specialised shop. Highly recommend, and I'll definitely be back!

Hayden Lawrence

Great service. Needed a replacement driver's side mirror glass for our old GTI. Harry's Euro had it in stock for a good price and shipped it next day. Very pleased with the transaction and will happily recommend and use them again.

SladeDaSlide

Been Working with Harry's Euro for almost 3 years now and I can highly recommend any auto-work or performance upgrades to be done by these guys. I've had my previous car and my current done by the team cheers to Scott and the boys for the work 🍻
