  I have had repeated problems with the DEF system . I went looking for a service center where I could have a conversation about my vehicle with an informed person at the front desk. I found it at Dales.

  I waited a year to see if there would be problems with a timing belt kit install on a Sequoia.  There are none and the Truck runs great, that s why I gave 5 Stars. I would go back.

  Excellent service.

They’re very professional and would always recommend them, the diagnosis was accurate and fast.
It was a  transmission failure  therefore I needed a replacement, which they delivered at a timely manner, despite the amount of work involved.

Great work and quality.

  A+++. I would highly recommend getting your vehicle serviced at Dale’s. Jameson and his team run an honest shop with fair prices, and the tech’s will treat your car as if it was their own. I’ve taken numerous vehicles to Dale’s over the years and have never had a poor experience.

  Yesterday morning as I prepared to leave my home, my car sputtered to start. I drove to Dale's and thankfully my car could get booked in to check the source of the problem. Within 15 minutes, I was called to advise me that I needed a new battery. Within two hours my car was ready for pickup. I have been a customer for many years and I have always received friendly, informed and timely service.

AUDI Walnut Shell Blasting FAQ

1) What is walnut blasting and why do Audis need it?
Walnut blasting is a non-metallic media clean that safely removes intake-valve carbon on direct-injection engines. Many Audis develop deposits because fuel doesn’t wash the valves.

2) How often should I do it?
Typical interval is 80,000–120,000 km, or sooner if you notice misfires, rough idle, or power loss. We confirm need with a borescope before recommending service.

3) Is walnut media safe for my engine?
Yes. Crushed walnut shells are soft, won’t damage aluminum, and are vacuum-removed. We block ports, control media flow, and verify each cylinder with photos.

4) How long does it take and what does it cost?
Most jobs are same day depending on model and access. After inspection we provide a written estimate; pricing varies by engine and required gaskets/parts.

5) Do you service more than Audi?
Absolutely. We’re the best mechanic near you for auto repair and service on all makes and models—European, Asian, and domestic.

Walnut shell blasting is necessary for DIT engines to
