Hi anyone have any idea why my 63 plate i30 diesel has a intermittent idle??
I've sprayed a whole can of EGR cleaner in NO JOY and I've even  disconnect  the  mass air flow  sensor the car drivers slow so connect the sensor back and car drives normal BUT STILL GET THE INTERMITTENT  IDLE . ANY IDEAS

mate WELCOME but ; " I have this thing that is possibly string, can you predict the length?"

 Gerard our chief clairvoyant is away meditating, so think about the question and come back with specific info .
eg  KMs , cold or hot, work done by professionals or their advice, and what the **** is intermittent idle? High or low revs or engine dies?
Other symptoms?

Sugar coating is an optional extra..  :snigger:

The more info you can supply the more likelihood of a remote diagnosis. It's difficult at the best of times to diagnose something like this without your head under the bonnet.

Might sound a bit harsh, but have you tried really trashing it when warm? Many diesels with EGR gets driven way to light & this builds up soot as you already figured out due to use of the EGR-cleaner :goodjob:

Btw. Liquids like EGR-cleaner is not a miracle-thing. If your EGR leaks i would instead remove it & give it a good manual cleaning with a brush & brake-cleaner instead (your intake will probably look the same as the EGR on the inside but thats a major operation)

Problem: Rough idle. My answer: Experience & a bit of guessing, but thats how kind of all faultfinding works.
