Taking 7 Yr Old Evo to a Nor Cal Dealer
 

I've been dealing with intermittent ASC & 4DW system service required gremlins for over year. I'm thinking of taking it back to Concord Mitsubishi, which is where I had my first Evo (also a 2011) serviced for the first couple of years. Has anyone out there had any bad experiences with Concord recently? Any other recommendations? I'm open to about anything in Northern California.

Here's my post from last year on the AYC Pump thread.

I think nor cal guys didn't have favorable experiences with Concord. Some of them seemed to prefer Daly City. I had good experience with Fairfield
when I had them do my clutch master, headlight level and pulley/serp belt about 4 years ago.

Should be covered under warranty if it's the AYC pump. Good luck

That's good to know. Fairfield is certainly more convenient for me.

Car is seven years old and I really don't care if it's covered by warrantyhttps://www.evolutionm.net/forums/im...ons/icon11.gif It certainly wouldn't be the most expensive part replacedhttps://www.evolutionm.net/forums/im...cons/icon7.gif I'm thinking it could be sensors but really I just want the warnings to stop randomly appearing.https://www.evolutionm.net/forums/im...cons/icon9.gif

If you are set on going to the dealer cool. Though, here in Nor Cal we have a great guy you may consider that is a big tuner here and does
maintenance for Evos. Search Gary Bains or Bains Tuning on fb or IG.

It's now warrantied for 100k miles

Thanks good to know.

Update: Talked to Fairfield Mitsubishi and turns out they do not have the proper equipment to diagnose my problem. They told me nearest shops with equipment are Oakland and Sacramento. So I'm going to contact Sacramento Mitsubishi (the one on Fulton) tomorrow.

Thanks for the support and kind words ...Bless up

Got ya man.

It's Anthony V. See you soon!

Thought I'd close out this thread with an update. The Sacramento dealer was useless. I talked to the mechanic and he did not want to deal with all of the aftermarket wiring (SST cooler and a bunch of gauges). He recommended Overkill Performance in Sacramento. I called them but they seemed very busy and the car's been in a shop black hole before. Ended up taking the car to DSG Performance in Sonoma.

DSG took over the service arm of Works. Works has had mixed reviews on this forum and I have had mixed results as well (although the two tunes I have had there have been spot on). They, and another shop in El Dorado Hills, have done almost all of the work on my current Evo. DSG went above and beyond to fixed the electrical issues and all of the warning lights are gone. They finished some other track upgrade such as big fans on my SSP cooler, finishing brake cooler ducting, accommodating bigger tires, and a harness bare and 4-point harness. All of this was done well and timely.

Car ran great on my first track day of the year was great until one of the new tires failed the first time it got to up to temperature. But that is another thread.
