EGR Cleaner smoke Popped and troubles
Posted: Sat May 24, 2014 10:55 pm
Hi, new here but i have lots of possible questions coming along as i try and help my dad out as much as i can.
He has a 2.0 Hdi 90 2002 406.
It was showing low mpg of around 30 - 32mpg so i said id give it a mini service, oil, filters etc and read to use egr spray into the air intake.
The engine prior started on first turn of the key, however now on a cold start, the engine strugles to start without waiting and giving it a little pump on the pedal. When doing the egr spray in short bursts the engine reved up a little each time, when id used almost the whole can, it gave a sort of backfire back out of the air intake and the engine reved up quite high, being alarmed at the unusual happening, i turned off the engine, waited a minute and fired it back up.
Now on starting up the car i get some white smoke on first starting it up which after a minute, clears itself, but still struggles to start from cold but okay at starting when warm.
Ive tried giving it a good thrashing to clear out any leftover egr spray and it does still pull realy well, just a bit concerned, could the egr have damaged the turbo? just can see why if it still pulls great.
Any info would be much appriciated
