Hi !

Newbie here - hope you can help.

I have a 2017 BiTurbo Vivaro that has suffered from what I can only describe as a periodic misfire / lack of power under acceleration or while on the motorway. It's quite intermittent but has been around for the last 12 months. It feels like a stuttering - like you're lifting your foot on and off the accelerator.

It's a works vehicle and they use an independent garage. In the last year it's had an EGR valve cooler, a fuel pressure regulator, a couple of fuel filters, fuel system treatments etc. Numerous visits and they couldn't fix it.

They finally bit the bullet and sent it to a Vauxhall dealer who have replaced injector 3. Problem still present. Back to Vauxhall again who changed the air filter and told me to run it on fancy diesel. It's still doing it !

When the problem occurs I get a series of error messages on the dash " check injection system", " check anti pollution system", "check hill start", "check esc" (probably others I've forgotten) as well as the engine management and service indicators.

Any ideas what it could be because it's doing my head in now.

Thanks in Advance

Garreth

Hi mate had the same misfire problem with my bi turbo Renault traffic same error messages, check esc, hill start assist, check anti pollution and checkinjection,it always seems to happen when I drive on cheap fuel, run the tank low and been running on shell v max,touch wood misfire has gone away hope it helps you, ian

Cheers mate ! It's had 1 injector (no 3) replaced - then replaced again under warranty. Same problem. Been in again - they said injectors 1 and 2 were "overfuelling" and quoted me £900 plus VAT !!! After a big argument they're doing them under warranty.

I'm going to buy some quality fuel - and set fire to the bloody thing - if this doesn't fix it !

Hi Gareth. Did changing the injectors fix the problem? I have exactly the same problem and error codes.

No it didn't ! The bloody thing is back at the dealers again as we speak. It's already been there a week and looks like it won't be coming back any time soon. The thing is an absolute heap of **** - as are the dealers. Worst vehicle I've ever had.

Hi chaps, I have the same problem but I have no fault codes. It like a hiccup randomly.

That's the one. Mine does it occasionally but sometimes it's pretty constant. It's had a NOX sensor, an EGR valve cooler, a fuel pressure reg and 4 injectors and it's still doing it. Been at the dealers for 2 weeks already (they're absolutely hopeless) had compression tests, leakdown tests etc. Still none the wiser and they want it for another week !
