Idle hiccups TDI

Try Shell regular? Or Tesco? 25% mix of Premium?

Some garages have the equipment and knowledge to let you pay for the (say) 30l of regular you have put in, then set the same pump for a prepaid £10 of Premium so you can pay for it all in one go before returning to car, put in the Premium and drive off.

That’s injector stiction. New injectors at thousands or use a quality fuel.

I watched injector live data on VCDS and all 4 injectors were around 0. So weird. No faults stored in ECU at all.

I am looking at becoming the importer of an additive that stops what is known as "stiction" inside the injector and is supposed to help with idle issues on Common Rail. Are you interested in trying it?

[WillUK]

I was trying to get my head around this, i thought if the injectors were faulty, this would affect overall performance not just idle, but im not engineer or mechanic in any shape or form

[Crasher]

At idle they are only open a tiny amount and stiction can cause them to open out of time and cause idle issues.

ok fair enough. any products worth a try? other than replacing injector

[Crasher]

Yes but it is not available in the UK, I am talking to them

I'm suprised this called "stiction" not triggering any faults

[Crasher]

How can it? The injector has no feedback of nozzle position to micrometer level.
