Multiple issues after installing oil cooler, intercooler, and radiator

[BuntaTypeR]

I've made several modifications to my Civic Type R (2,847 miles) , installing the following components:

• HEL Performance Oil Cooler
• PRL Intercooler
• PRL Charge Pipe
• PWR Track Radiator
• Acuity Super Cooler Reverse Flow Silicone Radiator Hose

Initially, I discovered a leak in the AC condenser and promptly scheduled a service appointment with my Honda dealership. At the time of scheduling, everything appeared normal with no warning indicators.

However, a week later, on the day of my dealership appointment, upon starting the car, I was greeted with a series of warnings: issues with the Adaptive Cruise Control system, Emission system, Road Departure Mitigation system, and Brake system.
After the dealership checked my car, the service representative assured me that they had resolved the problems. Upon my arrival at the dealership, however, the representative I had spoken to initially was no longer available. Instead, two other service staff members inquired if I had been briefed on the problem. I informed them that I was told the issue had been fixed and that I should collect my car.

One of the service staff members then explained to me that the problems likely stemmed from the modifications I had made to the car. They even mentioned that I had removed one of the radiator fans due to my modifications, which they claimed was the reason for the missing fan. Ironically, the Type R model comes with only one radiator fan. I chose not to argue, realizing that they were simply conveying information from documentation.

After clearing the error codes, they returned my car to me. Does anyone know the significance of the "2847 code - for ECM/PCM malfunction"?

Has anyone else encountered similar multiple issues?

Regardless, I am quite disappointed with Honda.



Below are some accompanying pictures:

I just want to make certain I understand this situation completely. Why are you disappointed with Honda? Are you disappointed with the dealership, the manufacturer, or both?

This car is very sensitive and will throw check engine lights for little things. Do you have any codes right now? And if so what are they? Do you have a scanner or hondata?

CS: AC not blowing cold

Tech is saying it is blowing cold at this time.

So, unless I missed it, you have yet to tell us if your A/C was blowing cold. You only mentioned that you discovered a leak in your condenser.

Did you mention the leak to the dealership? If so, was it to the first person you spoke with? Did you bring it up again while the other two employees talked to you?

I absolutely understand that you are disappointed. Sometimes, consumers and employees need to communicate more effectively.

Did you drive your car at all that week? Do you drive your car much at all?

After they cleared the warning lights, did they return?

My philosophy is that you just can't get mad at the car or the manufacturer if it doesn't start acting up until after you start screwing around with it.

Also this is why I don't want to modify my cars. I've been burned before too, but I didn't place blame on the dealer for it.

2847 is referring to the mileage, it can also be seen again where it states "A/C is blowing cold and operating as designed at this time."

Read the codes and go from there, @Jester04 is one of the most knowledgable and helpful members here.

Thank you for the kind words, I’m just trying to be helpful . I want everybody to enjoy their car stress free. I hate trouble codes since they can really stress you out wondering what the heck is wrong with the car.

Sorry to hear of your woes. With modern cars, it is important to do upgrades in baby steps to see how the electronic systems like or don't like the changes along the upgrade path.. Doing multiple upgrades at one time makes it more difficult to troubleshoot the root cause.

Since you already have a bunch of upgraded parts installed, can you go back to basics so to speak keeping the car stock and then adding one thing at a time? From stock to adding an upgraded radiator should be an easy swap. Drive for a bit and then add the upgraded intercooler to then check for leaks, sensor happiness, etc.

From what you stated, it sounds like you added several upgrades at one time and maybe did not realize at the time that a bump could have occurred resulting in the AC leak or other issues.

Pulling codes helps as a starting point. Sometimes that can be frustrating though as they may not seem intuitive since so many components communicate with one another on the car.

Did you disconnect the battery before installing the parts?

 

[PointByPatrol]

Nevermind, you did the PRL charge pipes, so you would have needed to remove the battery for the installation. I'd recommend buying a cheap code scanner if you don't have one already. I also suspect, as I've seen this before, that you may have a boost leak, and this will certainly cause a check engine light. The clamps for the PRL kit have to be really tight against the silicone hoses in order to keep them from leaking. Soapy water and a boost leak tester would do the trick for locating a possible leak should the code return, and I suspect it will return.

Starting the vehicle after power loss will also begin an initialization process, and you will see those lights. If you drive it for a little and, at times, turn the car off and back on afterward, it will clear.

The FK8 had two rad fans, right? That's why they think you removed one on your FL5.

The funny thing is, I'm not even mad the dealer techs don't know this. Installing aftermarket parts and then relying on the dealer to troubleshoot just makes their lives so much harder.

One would think they should probably know that the FL5 only has one fan, especially since they're basically accusing the customer of removing one... but on the other hand, they probably haven't had a whole lot of experience with the FL5 as they don't appear to be breaking and coming in for service unless someone modifies them.

I'm actively trying not to victim-blame here, this sucks and I hope OP finds a quick and easy resolution. But it's also important to have reasonable expectations. If you've done a ton of aftermarket stuff, you have to be prepared to deal with the follow-up consequences, and leaning on the dealer to bail you out isn't really as viable an alternative as you'd think... this is why I'm also actively searching for a reliable tuner shop I can trust before starting down this path of modifications. I can't be bothered to deal with this myself, and don't trust the dealer to be able to handle all my one-off use cases if I get stuck or need them to run another problem down that may or may not have to do with the mods on the car.

@BuntaTypeR where are you located?

@BuntaTypeR where are you located?

Based on the receipt, California it seems.
