WYNNS Diesel EGR System Cleaner Aerosol - Powerful Jet Spray for Deep Cleaning - Dissolves Carbon, Tar & Varnish - Restores Engine Performance & Prevents Starting Issues - 150ml

Engine management light on due to reduced flow in the egr. Used this can as directed, oh boy what a nerve racking experience. Into limp mode. Lots of active faults MAF sensors etc. But trust the process, remove fault codes on your scan tool. Test drive and clear the codes again afterwards. Worked a treat on my 16 volvo d3

Very good quality, trustable seller

I suppose it does clean but more intense work is required than just squirting this in the intake.Removal of parts to clean or replace is best.

I've had my car for 2 and a bit years, it's a moderately old car, 11 years and counting. I used this after some wynns 7in1 fuel additive. It was running considerably better after but decided to give it some egr/air intake cleaner anyway to keep on top of things. Honestly, the difference was subtle but noticeable, but I don't think there was much wrong with the engine to begin with.I only used half a can of this on my car, I don't think it needed more, and it took 20 minutes as it was, compared to the advertised 10. Maybe I just wasn't being aggressive enough with it. One thing I will note is that most people say to spray it into your air intake or just after the MAF, I read the instructions online and it tells you to put the spray in AFTER the intercooler, preferably into the air intake manifold directly (I put it in after the intercooler just before the throttle body), and also that the car should be run at just under 2k rpm, not idle like a lot of people do.After this, I took it on a run and instantly knew it had done something. The low rpm acceleration was as smooth as silk; I didn't even know there was anything wrong with the car before this. I just thought it was how diesels were. Again, I can't claim it helped my mpg or total power, but I didn't have much of a problem with that after the fuel additive, and my engine wasn't too dirty anyway, but smoothness it helped with.I will definitely be making this a part of my yearly maintenance schedule.

Didn’t make any difference but might be other issue so not leaving +or -
