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.

Also good for degreasing car windows on the inside to prevent fogging. Only use a small amount on a microfibre cloth. And keep all the doors open for a few minutes to avoid inhaling the fumes.

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

Very easy to use, used it a few times, have noticed smoother running of the engine right away. I noticed on the last one that I have not used yet it mentioned changing the oil afterwards, emailed them to confirm but did not hear back. Might want to check the instructions carefully before using.It's a good idea to use this before a problem occurs with the EGR as a preventative maintenance, it's cheap enough to do so, and much better than a big repair bill or a break down

used on a 2016 320D that developed a rough tickover which in turn causes issues being as it's an auto...a right pain. I had a new EGR valve fitted just a few thousand miles ago after the same issues so assumed it needed a mild clean rather than removal, (this stuff wouldn't of sorted that valve I can tell you)! Followed the instructions to the letter and it seems to have cured the problem, the tickover is now silky smooth and there is no hesitation when revving, pulling away or accelerating. I'm lucky in that it's a relatively new EGR that hasn't covered many miles so can't vouch for it working on a heavily carbonised 100,000 mile car. Just to mention it takes quite a while to complete the second stage where the remaining contents of the can need using entirely, you'll need a non whinging 'my ankles hurting' volunteer to help you as the engine needs holding at approx. 1800 revs. I could of removed the valve and cleaned it properly but for now this has saved time and appears to of done the job.

good product easy to use
