Hi,

Can anyone help at all?

I have a Renault Modus 2010, Spanner lit up on dashboard recently with a message Check Injection, when lit the car loses a lot of power.

Car has been put onto a diagnostics machine, the code P2263 came up.

All of the things for this have been checked, code was cleared, but within 20 mins the same thing happened.

Doing my head in now as to what it could be.

If anyone can help, pm me and i will send you my number.

Thanks

If its not an obvious fault such as cracked hose etc you'll probably need to use proper Renault diagnostics (clip) or its just a guessing game.

Try injector cleaner in fuel or do these still have air intakes?

I have tried Redex, when the fuel runs low the car runs a bit better but still sluggish.
Cant get over 55mph at all even when the light is off.

EGR fault I reckon, affecting your turbo - assuming its a diesel?

Its a Petrol

Assuming it’s a 1.2 turbo model...
First things first, it needs to go on a decent quality diagnostic machine. Renaults and cheap code readers don’t work, once code has been verified you need to look at live data.

With the engine off does the manifold pressure and mass air flow values appear right, where is the egr position?

If they all look ok I’d check intake pipes, boost hoses and intercooler for any splits... sometimes they can be very hard to spot... but keep an eye out for any oil deposits on the hoses and pay careful attention.

Another possibility is the vacuum line going to the turbo actuator or the actuator itself. (Even could be down to the vanes in the turbo sticking.... check actuator rod moves freely by hand)
