has anyone got any experience with the wynns power 7? It’s a bit pricey at 35-50£ depending if I get it from Halfords or online websites. Did pick up wynns extreme system clean but says it only maintains an egr so idk how effective it is.
would appreciate some advice.

I took the one off my diesel Jag, and cleaned it out by first scraping the bulk of the gunk out, then using a variety of degreasers and bathroom foam cleaner, before finishing off with several baths of hot water and detergent, then clean water, then blow drying it.
It has been back on the car for several months, with no issues.
The trouble with many of these spray in cans is that if the ingredients hit the target, then they might do something, but if they miss, and they invariably will, then that is a lot of wastage. Also, any crap that dislodges may end up in areas that are more expensive to clean/repair/replace"},{"@type":"Comment","@id":"https://www.hotukdeals.com/comments/permalink/51340673","author":{"@type":"Person","name":"Toon_army"},"datePublished":"2023-11-02T23:55:00.000Z","text":"Cleaned mine last year on my Astra, took about 30mins to remove, would have been faster but one bolt was a nightmare
Used to APC and Super degrease. I've heard people using fairy washing liquid

Needs manually cleaning or replacing.
Maybe consider having it mapped out, they're a nightmare. So long as it's not stuck open it'll run much better without it."}],"commentCount":11,"interactionStatistic":3,"articleSection":"Ask"}
