England Decoking? Questions

Hi

New to the mini but wondering about the Decoking issue that seems to plague these engines

I have the 2010 clubman s (184bhp version)

I have a bit of a rough idle, uneven power distribution when the engine is cold. This appears to disappear when the engine is warm. Probably within the first 5 minutes of driving. It seems quick enough on normal driving and in sport mode. No signs of hesitation there.

The car has done 32000 miles.

Question is, how do you know it is coked up??

Should I be concerned at the mileage we are talking about

Who is best in the northwest to inspect and deal with this


I ask all this because I'm looking into tuning, Chip, map and exhaust work and obviously the engine needs to be sorted/or deemed fit before I go about making upgrades.

Many thanks again

Mike

Hi ya

Normally when you have a carbon problem it will show up when the car is hot and under load, you would get a misfire and hesitation.

It could be a lot of things causing your issue, when was it last serviced.
Have you run any bg44k fuel system cleaner throw it.

My advice get an air/oil separator fitted this will help prevent carbon build up

Hope this helps

Really common on the pre-LCI models. Really heavily discussed. Can be so subtle you don't even know.

For the record a catch can (from new) will reduce it, but won't stop it, or fix it once you have it.

Subaru have used a can of intake cleaner every service for years. Looking like this is good practice on every direct injection engine. Fuel additives don't work because the fuel goes directly into the engine and not sprayed onto the valves (where the buildup is).

We had a club event with close to 20 cars. Only 1 person could notice anything was wrong. All (on the dyno) were down close to 20hp and blowing black smoke under load. Only proper fix is to get an intake blasting professionally done (~$400).

By the time you feel the hesitation you have a really big problem
