I have a 2005 VW Passat TDI. Car has 180,000 miles from factory, as I am the first owner. Car started having problems with the cruise control that was quitting on me all the time. VW was asking $2,500 to fix the problem: The built up of greasy dust in the air intake preventing the car to run properly. I talked to Honest 1 Auto Care Manager about my problem. He answered me “No problem, give us the car for a week and we will have it back on the road.” Instead of replacing a myriad of parts and sensors, he just cleaned up the entire system. 500 dollars later, the car has been running like a new one with all the muscles of a new Diesel engine. The 6,000 miles I covered with the car since October speaks for them. I strongly recommend Honest 1 Auto Care!
