I got the carbon cleaning service done and 4 new fuel injectors replaced.
My GTI runs better now. Idling is a lot cleaner and sounds cleaner.
the valves were dirty… even though I did carbon cleaning 5 years ago…
KM wise it’ll be 50,000km ago… and carbon built up pretty badly.
not that bad but it’s bad. I’ve seen worse on other 2.0T’s to be honest.
Here are some before and after pictures:
I recommend doing this service if you plan on KEEPING your car for another 5 years.
or if you have misfires (cold start misfires)
Extended crank start during cold starts, or poor mileage.
I’ve had all these symptoms so I decided to do this service along with new fuel injectors.
I changed the spark plugs, ignition coils, PCV, rear main seal, checked starter/alternator so I did narrow it down to fuel injectors and carbon build up.
I got this service done yesterday evening.
I haven’t started the car yet, planning to do so in a few hours and I will record how the car turns over during cold start for an accurate reading and so I can playback the video file on my phone and listen to how the car starts after new injectors and after CC service.
Get all four fuel injectors replaced with carbon cleaning service for best results and for an efficient service. It’ll cost you a bit more but it’s peace of mind knowing you did both all at once.
from what I’ve seen and heard, fuel injectors go bad on most German cars. Especially Audi/VW’s.
like my shop said: these engines are designed to break down at some point and drain your wallet.
I appreciate the honesty from the shop.
my response is that I’ll make the money back and 10x more and be prepared for anything life throws at me.
money moves the world so gotta have a ton of it.
I’ll make sure the next German car I buy is a naturally aspirated engine.
direct injection engines have this problem and actually have more issues that can happen compared to N/A.
but it’s not as fun as turbo/direct injection engines.
Gotta pay to have fun!!!
