Liqui Moly8931 Catalytic-System Cleaner, uncoloured

Use it as instructed on the Company official website. Works perfect, you will need to erase computer errors, eventually. Engine work smooth.

Great value for money 😀 transformed performance on a 2003 petrol and brought emissions to pass level. Spray as a mist into air body whilst engine is set to 3000 revs the revs will purge and judder after take for a spirited run 😉

Arrived as described - works well.

Without the funnel that's supposed to come with the container, you cannot get the product into the fuel tank without sticking your finger in to the throat of the fuel filler and getting most of the product wasted.

Used two of these, spraying it into the throttle body as my X5 failed its MOT on emissions. I did as directed on the can, then took it down to the garage and they checked the emissions quickly only this time, it sailed though the test.This really works !!Excellent value for money

Can’t read directions due to there being a sticker in foreign language stuck right over English information

Item did what it's meant to.

U need to find a spray bottle some how attached a pipe then spray it in the throttle body with car running I didn’t see that in the guidelines . Not happy . Love the rest of there stuff . I thought u put it in the tank . Not a happy bunny .
