Wynn's Turbo Cleaner - Safe for Diesel & Petrol Engines - Dissolves Carbon, Gum, Varnish & Tar - Restores Turbo Geometry & Air/Fuel Ratio - Compatible with DPF & EGR Systems - 200ml

Wow! Okay so this fixed my P0234 overboost fault code. Apparently my variable geometry turbo was stuck open and wouldn't idle nicely. This stuff has cleaned it right out! And probably half the stuff behind it too. Let's be honest a new turbo is nearly 400 quid plus fitting.... I got a can of this under ten quid and then I bought another one while the price was still low. Definitely a must for diesels that have been running supermarket diesel all their lives, and a lifesaver for P0234

superfast delivery, quality products, great comunication, very well recomended, thanks AAA+

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, and some Wynns EGR cleaner. It was running considerably better after those, but I decided to give it some Turbo Cleaner anyway to keep on top of things. Honestly, the difference wasn't noticeable, but I don't think there was anything wrong with the turbo to begin with, hence why I couldn't give it a full 5 stars, as I am unsure how well it worked. What I do know is that it didn't break my car, and wow, was it scary adding this stuff. Most people put this into where their air filter is, or after the MAF, which, from what I can tell you, MUST not do. I had to go online for the instructions, and they mention that you can't get this into your intercooler, and yeah, that makes sense. This stuff is strong enough to strip paint off your car, so you don't want it near anything fragile like your MAF or intercooler channels. I put it in just after the intercooler and just before the throttlebody, it tells you to gett as close to the intake manifold and that's the best I could do, I had my dad on throttle duty and it tells you not to exceed 2000rpm (and keep it above 1800 not just leave it on tickover), but he doest understand subtlety despite my specific instructions and when it tried to stall (the spray does that its expected) he just floored it, but its good to know that this doesn't actually break your car, may have made it less effective though. I ended up only using half a can, as the "10 minutes" they say it will take is complete rubbish, and I was there about 20 minutes to use just half the can.

Great product and price. Works great does what it says on the tin

Seemed to work

Easy to use

Does the job well.

Wow I noticed a difference straight away after using this turbo cleaner on my Volvo s40… will use this again, fully recommend. A+ from me. 👍👍👍👍
