Emissions testing service near Elmhurst, IL

The ONLY guys who work on my German autos. Tony Jr. is a class act who will give you the straight-up and a ride to the office if you work nearby. Sure they're a bit more expensive than the Midas shop around the corner, but you certainly get what you pay for...peace of mind!

I have high expectations for anyone who works on my vehicles and Rennology was up to the task. They are very professional and completed the work in a timely manner.

Drew and team always get the job done in an efficient, professional and friendly way. Kudos to the Pit Shop team!! George Hvostik, MD

Ongoing problem for 9 years. Dealer repaired emissions error and check engine light returned in two weeks with same problem. AACCEL repaired the emissions, and now I can fuel the car in less than 15 minutes and pass the Will County emissions testing.
