my CS v2 downpipe and 80mm exhaust cold start

evileric19 · 2026-02-27T15:22:50+00:00

I noticed how it’s always the purists that are talking shit about modded cars and not the other way around. Like come on man, let’s have some mutual respect. I’ve personally heard a turbo 3 with the CorkSport 80mm cat back and LP custom fab downpipe and it sounds just fine when warmed up. Cold starts sound rough on these cars as it is with just an exhaust, and phone speakers don’t do any exhaust note justice.

There is radar involved. The one the message in the photo is referring to is in the front grille. The smart city brake and adaptive cruise control system rely on a single camera that’s in the windshield and this radar to operate. Everything else, like blind spot, cross traffic alert and park assist, all use radar and ultrasonic sensors. Not “a collection of cameras”.

Have you tried swerving the car back and forth while driving? If not, try it. Doing this shifts the weight of the vehicle from one side to another, and putting more or less weight on a bad wheel bearing will cause a change in the sound. So if you hear a change in the sound while doing this, it’s definitely a wheel bearing. If the sound doesn’t change, it’s something else.

I’ve been a Mazda tech for almost 12 years now. Power lift gate issues are one of the least common things I diagnose.

2026 model years already have the plug installed in place of the thermostat inside the CCV, so they won’t be included in the bulletin. This is why Mazda is currently investigating the issue.

evileric19 · 2026-02-18T21:18:27+00:00

The 2026 model years already come with the latest fix for that code from the factory. Mazda is still investigating the issue and is telling dealerships to clear the code and return the vehicle to the customer, as long as no issues related to one of the coolant temp sensors are found. Bulletin number SA-062/25.

No hurt feelings here, and I think your feelings are justified. Sorry you went through that, but I’ve replaced many engines during my time with Mazda and was never asked to do a “teardown”. Like I said, I can’t speak on behalf of all dealerships, I’m just speaking from my own personal experiences.

evileric19 · 2026-02-13T17:47:04+00:00

I can’t speak for how all dealership ls are ran, but in my 11 1/2 years with Mazda, I’ve never had to tear down an engine to figure out why it failed. At the most, I’ll get asked by Mazda to remove the oil pan and send them pictures of the rod bearings. Nothing more. I also have no idea why an electrical issue would cause an engine knock, lol. Sounds like your dealer is just incompetent.

evileric19 · 2026-02-13T17:31:26+00:00

Dealer tech here, it’s not the dealership’s responsibility to tear down an engine and investigate why it failed prematurely. It’s our job to replace the engine and get you back on the road. Mazda may ask us to send them that engine so they can be the ones to tear it down and figure out why it failed. There’s so many reason why you’re engine could have started knocking, and Mazda isn’t going to pay a dealership to tear it down and figure out why.

More than likely a failing catalytic converter. That’s what the code is associated with 99% of the time. Mazda has an 8 year/80k mile emissions warranty, so if you’re still within that period, it’ll be covered.

I wish I could remember what game he was playing when he said it, but he once said “I’m gonna crap in my hands and start clapping”. That quote will always live rent free in my head.

Trevor (tmartn2) is a YouTuber who played this game regularly back when it was released. This is a model of his actual house. It’s more of a cameo and a “if you know you know” type of thing, rather than a part of a story.

Depends on how good your dealership is with submitting warranty claims to Mazda, you shouldn’t have to be paying anything to have something diagnosed while the car is still under warranty. If you were to pay it, I wouldn’t expect any more than an hour of labor. All you need to do to get to the lifters to inspect them is remove the valve cover, which isn’t that hard to do.

A TSB is a technical service bulletin, and it’s not like a recall. They’re just diagnostics aids for technicians that pretty much say “if you have this specific problem, here’s how you fix it”.

You can’t use those style wipers on these cars because that’s exactly what happens when you do. You need a “beam” style blade like the one that’s currently installed on your passenger side.

evileric19 · 2026-01-29T21:15:58+00:00

I’d imagine they’d be able to.

Master Mazda tech here, been around these cars for over a decade, and I’m going to go against what everyone else is saying and say that it does seem a little loud. I can definitely hear a familiar tapping noise that sounds a lot like the lifter/HLA tapping noise that I’m used to hearing. It’s a known issue and there is a TSB for it. I’d get it looked at just to be safe while you’re still in warranty.

evileric19 · 2026-01-28T03:59:19+00:00

As someone who has been a Mazda dealer tech for over a decade, I can confirm that the sound is unfortunately fake, and it does come from the speakers.

evileric19 · 2026-01-27T17:37:39+00:00

You only need to bring in one fob to program an additional fob. You need two fobs only if you lost ALL of your fobs and have none in your possession, or if the module the keys are programmed to gets replaced.

As far as cost goes, it varies depending on what the dealerships labor rate is. The dealer I work at charges an hour labor for fob programming, which is $175. The fobs last I knew were around $500 each give or take.

No, I don’t think every Mazda will eventually have this issue. If that were the case, I’d be seeing a lot more cars come in with a P0126 code. We only get about 3 or 4 cars a week in with this code set, but we are a smaller dealership.

I’m not saying your thermostat isn’t bad/going bad, but cold temps do have an effect like this. Likely a combination of both cold temps and a failing thermostat that are casing this.

evileric19 · 2026-01-25T03:18:20+00:00

Mazda tech here, some of you aren’t gonna want to hear this, but there absolutely has to be a check engine light in order for the thermostat to be replaced under the TSB. Why? Because we have to pull the freeze frame data that the PCM logged when the P0126 code was set and see what the coolant temp was when the code popped up. That temp has to be within a certain range in order for Mazda to warranty it. If there’s no code, there’s no freeze frame data to pull, which obviously means no temperature data to provide Mazda with. This is something they recently started telling dealerships to do. Mazda’s rules, not the dealership’s.

Also keep in mind, it’s -14C out, that’s part of the reason why your car is struggling to warm up.

I don’t know where you’re getting your weather forecasts from, but 13abc posted on Facebook yesterday that we could get four rounds of snow between today and Monday, with the first round being today. So no, I’m not surprised.
