2.0 CDTi No Power, No Warning Lights

[Kayos]

2015 Insignia

Serious lack of power, will not rev past 3000 rpm

No warning lights, although service due soon pops up on dash when first started

Any ideas of the first things to check?, will get it on a code reader asap

I had similar limp mode with Mazda, when oil level was below min. Also, no warning lights.

ECU connection issue, dirty fuel, so maybe injectors and and one or all the TPMS, ( wheel/tyre sensors which might also cause limp mode and no warning lights ).

An OBD2 reader will be your friend here but whatever you do don't clear any error codes, let your workshop do this, let them see the raw codes.

Unplug the map sensor. See if that helps.

Doubtful on the fuel but can be checked

TPMS interesting, ran fine with a tyre low so all 4 checked, however it did run fine initially

Codes won't be cleared, it is likely it will be back at the dealers before anyone has a chance to put a reader on it

Early this year cheap fuel caused my Yeti to go into limp mode but had ECU warning light, I cleared the code and now every 4th fill, E5 goes in.

November this year, Yeti went in to limp mode, I had been getting a low tyre pressure light but checked tyres, all seemed ok then one evening, limp mode no warning lights, turns out it was a wheel sensor.

No different, other than putting the check engine light on

Went off when reconnected and restarted

Ive got the GM tech 2 diagnostic tool here if you need it, pretty sure it does those but not tried myself

 

[Keithmac]

You can have faulty Diesel injectors with no fault codes.

Does it sound like it is off one cylinder?.

bloomin non ev vehicles.

I did have a problem with just one of the 12 I had long term. Turned out to be a sticky or faulty throttle position sensor. Can't remember if it showed up fault codes.
I reckon the Insignia with that engine is very under rated. I preferred them to the Audi A4 and BMWs etc I had off Enterprise and Avis. I would keep them for about 24000 miles or so of very hard driving - about 6 months - then swap out. Always asked for Insignias and only 1 minor blip with all the ones I had.
Miss them!

Perfectly fine except will only rev to 3k, and doesn't have any power

It's heading back to the dealer on Wednesday, however depending on timings/outcome I may take you up on that

Not to derail my own thread, the VW ID4 (EV) was with VW for nearly 5 months, after it left me stranded in Wales

 

[m_c]

Service vehicle soon on that means that there are are non-emmisions related faults stored.

 

[MetalMonkey]

Could be all sorts - Boost valve, Blocked DPF, DPF sensor or pipework, Boost leak.

Without a session on the diagnostics you'll struggle to narrow it down quickly.

Unfortunately I don't think you can "pedal test" these to get the codes either, its OBD only AFAIK.

Is it not revving past 3k at standstill or when driving? If its at standstill I don't think they are supposed to rev higher so that might be red herring, the low power should throw up some codes. Get the oil pickup o-ring replaced if the car is a keeper, the youngest vehicle ever donated to us was an insignia with perfect body and dead engine for the sake of a 20p o-ring. Have you checked all the pipework under the bonnet for leaks?

It won't go past 3k standstill or driving

I've seen the oil pickup thing, on the list if it gets sorted

Haven't checked anything yet, going back to the dealer on Wednesday

 

[Ruffian]

Maf, blocked egr or turbo actuator.
Usually will pull a fault code though
But seen them have issues without.

Might get lucky with a split boost hose, is it making more black smoke out the exhaust than normal?

 

[Bullet2012]

its really simple Mr Kayos, it wont work if its running out of fuel and unfortunately, unlike a proper vehicle it will not refill by plugging it in, if you want it to go further you need to take it to a government tax station and fill it up with fuel that is liquid at sea level air pressure and temperature. Do not ever consider one of those cold high pressure fuel systems that create almost zero pollution.
