Tarkistakaa polttoainepumpun kunto, jos

palaa usein, voi olla merkki syöpymisen (valmistusvika) alkamisesta, jolloin koko ruiskutusjärjestelämä (menee tukkoon suuttimet) joudutaan uusimaan, ja se maksaa tuhansia ja tuhansia euroja:

Kun kyseessä on valmistusvika, niin vian korjaa aina myyjä/valmistaja (vaikka takuuaika olisikin mennyt jo umpeen), ellei auto ole jo hyvin vanha (esim. 10 vuotta ja ajettu 400.000-500.000km).


Mazzers

I have a 2004 1.5DCi Megane, I just recently had the sme fault as you come up. It turns out that injector no.2 was faulty.

Upon investigating that further, it seems all 4 injectors were on the verge of being faulty. It turns out my fuel pump was disintigrating introducing tiny iron filings into the system. This is a common fault with Delphi pumps which is what a lot of Meganes have.

The fix was massive and very expensive. Had to replace the entire fuel system from tank to pipes to injectors to rail to pump.

I bought the parts myself off a Renault dealer in the North and got ax ex-Renault Mechanic to do the work for me in Galway saving a fortune (but it still cost 2.5k)

Your problem may not be as bad as mine, just be aware.
My advice to you is to get a diagnostic computer plugged into the car, this will tell you which injector is acting up. Also get a decent mechanic to inspect the fuel at the filter, look for tiny iron filings.

You can get injectors reconditioned or replaced. Also if you are near Galway and want the no. of my ex-Renault mechanic, pm me.
