Laguna 3 2.0dci 150km: Excessive Smoke & 14L Consumption in City - Solutions/Experiences?

Hello gentlemen! I have a lagoon 3 2.0 dci 150km. The toy car is good, it doesn't smoke, it has power But it smokes a lot in the city, namely 14 liters. Has anyone ever had such a case?

Damaged injectors or flow meter or blocked EGR and DPF.

There are no fairies here, so KLIP will tell you the truth.

Regards.

Today on the route to Łódź speed 140-150 km / h burning 8 liters! I think it's quite good combustion. But these 14 around the city is a massacre. I don't think that injection would kick. But yes And as a friend of mapet says the clip will tell the truth soonest

Today, gentlemen, I noticed that you feel fuel from oil, so this can be the reason for a large combustion. On Wednesday, I have an appointment to hook up the car and if I know what's going on, I'll let you know

Fuel in oil - unburned DPF>

Buddy decibel but you also had such a case? Friends tell me that they can also sit injection

Damaged injections would cause kicking or hard work during rapid acceleration.

Either way, don't ride it because you may end up with a hole in the crowd.

Yesterday hooking up the clip and dpf collapsed. Regeneration procedure done, today oil change and observation if oil does not pour further. But surely the dpf was collapsed. And egr for cleaning.

And the chest is not a machine sometimes

Hello. And what does the automatic transmission have to do with it? ? I have the same situation!

And the machines in the city smoke like dragons.

Tz how much? Mine doesn't want to fire me I thought it was injection molding. My average in the city shows 9-10 liters / 100

And how did the topic end? Because I smoked a lot, was it enough to burn?

The fuel pump started filing and everything went for injection regeneration of the pump 1100 new injection 2700 and washing the fuel system 4500

Do not scare me. What about how many kilometers the fuel filter was changed? Are these particles so small that the filter does not spill out? I heard about this in a4 b8

These are micro filings, the guy showed me my pump, but probably it is already in these cars mine had 230 thousand

Good to know. Thank you for the information. Regards

After all, it is a toilet pump and not the one in the tank so the filter has nothing to it.

Good day. For several months I have owned Laguna 3 2.0 dci 150 HP, r. Prof. 2012 phase 2, coupe body. Fuel consumption exceeds that provided by the manufacturer, namely around the city, with very gentle driving you can not go below 8 liters. I know someone wrote here about 14 in the city - this is the way to go. On the route, not much, because between 5.5 - 6.0 - also driving very economically. According to the manufacturer, it should be around 4.0 and around 6.5 in the city. Why am I writing about this?
The wife drives every day Renault fluence 1.5 dci 90 km and achieving the wear declared by the manufacturer is quite real. Under what conditions does the manufacturer test vehicles obtaining such results? My previous car was a Vw Touran 1.9 tdi 105 HP with a 140 HP program, heavier and taller than the Lagoon and smoked less in the city, also on a 105 HP program. Factory fuel consumption could be achieved in real life. Is everything ok with my lagoon? In the summer I plan to go to some specialists from the diagnosis, because despite the fact that 8 liters is not 14 but in my opinion it is too much.

Look for a good specialist around the CLIP diagnostic program. This will definitely reveal and eliminate any engine shortcomings.
Although your Lagoon's engine appetite is not that great and may also be due to its course.

In principle, you should set up your own thread.

Greetings.

According to my view, connecting to CLIP will not help much. If the engine does not kick black and does not require frequent DPF burnings or oil changes, then the combustion is correct.

Nobody believes in such fairy tales.
Combustion is, among others, a reflection of how much resistance the vehicle has to overcome to move.
These resistances include size and width and type of tires. The condition of the suspension and braking system, the speed at which the vehicle moves, the installation of additional "bodywork", energy consumption "on board", etc. Most often the main factor causing increased fuel consumption is also the "manager"

I suggest an experiment. Swap cars with my wife for a month.
In the course of my professional work, I did some hundred test drives with clients complaining about high fuel consumption. It never happened that I would not fit in the average declared combustion in + max. 0.5 liter.
What's better, knowing all these rules, my car smokes on average 50% more than declared by the manufacturer

8 liters is too much. there must be something wrong. 8 liters will pull on the highway at 160 km/h. I have two lagoons, 150Km manual and 175 HP GT. And there is a problem with this GT: the counter shows that it burns 5 liters and it really pulls 8. I have to check what's going on. Maybe someone has encountered it.

They don't smoke like dragons. Maybe 3 liters of petrol is like that. I have one and when it enters the city, the route was 8 and in the city it was 11.5, but 2.0 hdi - nothing like that.
However, I have a problem with low fuel consumption - and it's a lot - in Laguna GT 175 automatic. It shows fuel consumption, for example, 6.3, and it goes down to 10. Today I checked it on a full tank, I gently did 100 km, indication 5.1, 8 enters the tank. But I checked it on the road yesterday, because I did maybe 510 km and flooded ... 46 liters fuel. Normal driving with which it should be max 6.5 liters compared to a 150 horsepower manual. But the tank tip doesn't lie anymore, you can see how the fuel goes down, it's half and then the distance counter shows that it's supposed to be 700 km to do, but later it adjusts the less there is in the tank. The given combustion does not correspond to the real combustion.

I once had such a case in a Touran 1.9 Tdi: freshly after buying the car, the computer showed fuel consumption at approx. 5 l / 100 km, and after refueling from my calculations (km traveled and the number of liters refueled) it was 7.5 ...
A visit to a good car specialist and it turned out that the ignition was incorrectly set, which caused the computer to calculate incorrectly - it underestimated fuel consumption. After setting the ignition, the computer began to show more and the real fuel consumption decreased slightly. The theoretical and real fuel consumption differed by maybe a few tenths of a liter ...

And back to my Laguna coupe (record from May 6, 2020) - I still drive it, I’m very happy. After a few years of operation, I can say that we "reached" and understood each other.
It burns a little less around the city, but this is due to the fact that I often (unfortunately!) drive on short trips, i.e. with a cold engine, and then there is no need to expect the engine to burn 6 liters - because that’s probably what the catalog / manual says. There are no miracles. Traffic jams, more and more traffic, more people standing in the city than driving. I prefer to take a roundabout route myself to avoid traffic jams and although I cover a greater distance, I will probably sleep the same. Of course, I treat the accelerator gently. Warm engine - less fuel and engine wear. The route - superek, you need to "blow" the engine and dpf. Excellent fuel consumption. Depending on the speed and driving style, from 5 liters upwards. I managed to "go down" below 5 a few times, but it was a "grandfather’s" ride.

The voice of reason 👍 .
Sometimes it takes time to come to certain conclusions on your own 👍

Properly operated Laguna 3 Grandtour should consume: 100 km/h - 4.1 l/100 km, at 120 km/h - 5 liters, 130 km/h - 6.5 l, 140 km/h - 7 to 7.5 l.
