Nissan Quasqai diesel, red engine light

Millionaire only not

Hi lads

A friend of mine has 2014 quasqai diesel brought from Uk last year about 60,000 km !
An red engine light has come on brought it to her local garage there saying turbo , serviced but told her drive hard to free blockage !
Would that make sense?

Has it booked in with main dealers for diagnostic!

Does anyone know what problems these cars usually have ! Any help appreciated

No, that makes no sense, if the mechanic meant the DPF (particulate filter) there would be some logic to it, as harder driving can force them to regenerate and burn off the soot (and hence unclog the filter - although if the filter gets too blocked then this is not possible), but turbos don't suddenly get 'unblocked' if you drive the car hard and in fact could do more damage to the car, a turbo is not a cheap thing to fix so you don't want to do anything that could make a possible failure a certain failure.

If the filter is clogged it's an expensive replacement but in certain cases it can be cleaned.

What driving is the car getting?

Short drives around Dublin or motorway driving....

60k miles or km?

What's service history like

I'd recommend staying clear of main dealer especially as warranty is over.

They will charge big time so get a good indy you know is reputable.

60km , has service book from Uk and looked genuine
Doing 20 km to work 3/4 times a week , plus school journeys
Serviced twice since it came , once when bought and local garage after that !

Could it be possible he used wrong oil ? Would that cause it ?
I know she puts in that applegreen diesel from time to time !

It seems seriously tight and Jeep looks genuine , drives perfect I’d imagine mileage looks genuine but I’m not a mechanic!

Honestly the driving style doesn't suit.

It needs a good solid run on a motorway and at high revs for it to clear itself and regen.

That driving is suited for petrol all day long.

I've had no issues using apple green but have heard a few things such as not using additives or not as good a quality but I'm not fully convinced.

Many use it and cars drive on no issues.

Driving a car hard doesn’t clean the dpf out.

No but it does need a long run for it to work.

Long run ≠ driving hard

I didn't say drive hard but high revs will help as in doing 120-130 if possible...

The mechanic in the OP said driving hard will fix it

Ah sorry get you now, yeah that's mad.... Mechanic should know better then that.

Also I know she has said it’s lacking power when she first drives it in the morning !
Is the turbo on the way out ?

I would ignore anything the first mechanic has told you and wait to see what Nissan say.

I don't think the driver is doing enough mileage or type of commute suitable for a diesel.
But that's neither here nor there.

The best advice I can offer, is the listen to your mechanic.

Things often get confused or misunderstood, so if a competent mechanic tells you that you need to do X Y or Z.. do that.

colm_mcm

What if your mechanic tells you your turbo is blocked, and the cure is to drive the blockage out by hooning a car which is probably in limp mode?

Then he's not a competent mechanic.


Only listen to a competent mechanic.. that's my advice.

Edit: I forgot to mention competent in my op

mea culpa

Wouldn't it be even funnier if it didn't have a turbo!!!!

We’ll know Monday , sorry but even I won’t see it before that

It does, just mean imagine mechanic saying that and none there.

If it were a turbo you tend to hear metallic sound and also oil mix etc.

Definitely sounds like egr but more likely dpf.

Diesels dont drive at high revs.

My 1.6 does 120km/h at 1.3k

Not if you’re in 4th.

Hi, is this qashqai j10 (up to 2014) or the newer shape j11 2014 onwards? If it's the older j10 could be a few things. The main ones we used to come across were the plastic air intake pipe on top of engine splitting on seam which caused dpf to block. The other mIn one was exhaust pressure sensor tube (metal pipe at back of engine) blocks with carbon and stops the sensor reading correctly and thus not allowing dpf to Regen. Turbo actuators can also go due to top turbo hose dripping oil on to actuator diaphragm. Need more info really like a diagnostic dtc

Lyan

Nissan, diesal, and turbo, are three things you don't want to see together OP.

Millionaire only not

Punisher May have it right this sounds like what it’s doing !
The local garage had the light off but came on again !
Also this guy blames small mileage like what ye have said being the problem !
Also being a Nissan / Renault being the main problem! Lol

It’s a 2014 last of them models I think!

Ok so that's the j10 model. The engine itself on those is pretty decent , just little glitches. It's rare for the DPF to block on their own without something failing and causing to block. Unless your doing really short journeys. The dpf doesn't tend to give trouble on those , it's normally the fall guy for another problem on the engine itself. I wonder if the plastic air intake pipe split, or is still split which is causing the dpf to block. The dpf may regenerate once the engine fault is erased , depends on soot content . A forced regeneration may be required

Thks guys for ur help , she brought it in has that blockage of soot like ye said !
They did that regeneration and seems ok at the moment !
Checking it again in 10 days !
