Problems with purchase of Koleos

TenBeers

I am no car expert so any feedback is appreciated.
I also understand from reading other posts that many believe the DFP filter should be removed in some cases

Bought a Koleos from new 2.5 years ago and has given nothing but trouble.
Was bought as a pre-reg from major Renault dealer in Mayo
Paid a hefty deposit and decided to take the rest on five year repayment plan as warranty and break-down assist were covered for 5 years.

First issue: Get the finance papers which were very illegible and requested a new copy.
Turns out the interest rate for repayment was now 9.4% instead of the agreed 4.9%.
Both parties blamed each other for the "error".

Then the anti-pollution filter lights started to come on(many times) with other warning lights. Car was brought to dealer on all occasions and different reason was given every time it was brought in. My style of driving, these cars aren't made for these roads, I must be doing short journeys (I'm not),etc.

The second last time this happened, I was told that a full "factory reset" would be done and that this issue would not arise again. They put up over 700km while testing the car with no offer of compensation. Car only lasted a week without the lights coming on again. This time they decided to put over 1500km up again without any offer of compensation or extending the warranty.

Here is a list of work that Renault have stated was carried out on the car:
1.07.12.2018 INJECTION COMPUTER
2. 07.12.2018 UNIT and PLATE, CONNECTION, FUSE
3. 17.06.2019 UNIT and PLATE, CONNECTION, FUSE
4. 17.06.2019 UNIT and PLATE, CONNECTION, FUSE
5. 25.09.2019 INJECTION COMPUTER
6. 25.09.2019 INJECTION COMPUTER
7. 05.11.2019 UNIT and PLATE, CONNECTION, FUSE
8. 05.11.2019 UNIT and PLATE, CONNECTION, FUSE
9.08.02.2020 UNIT and PLATE, CONNECTION, FUSE
10. 08.02.2020 LOWER ENGINE, MOVING PARTS, HOUSING, COMPLETE ENGINE
11. 24.02.2020 Service
12. 06.03.2020 EGR (EXHAUST GAS RECIRCULATION)
13. 07.08.2020 SENSOR, CONTROL UNIT, PROBES
14. 08.10.2020 INJECTION COMPUTER
15.17.10.2020 UNIT and PLATE, CONNECTION, FUSE

This conflicts with the information that I was given from the dealer, which Renault had requested from the dealer and I had to ask for multiple times.

Anyway, finally get the car back from dealer the latest time and the car was in a despicable condition.
Oil or mold on the upholstery (not sure but don't want to attempt to clean incase I make it worse)
Paper cup from a restaurant left spilt all over the middle console (can't post photos)

One of the looniest posts I've seen. 50kms is too short but 20kms a week is fine. Care to elaborate on the science?

Accumulation of particulate in the filter and is dependant on the driving style and distance.

Someone doing a 50km commute one way is doing 1000km every two weeks. It takes the granny going to the shops a year to accumulate the same mileage (and soot).

About the worst journey you can do in a modern diesel would be 20 mins one way commute on motorway(~400km/pw) or N roads(~250kmpm).

Long enough at motorway speeds to do big milage every week and build up lots of soot, but short enough that a regen cycle never has a chance to complete.

Coupled to that, the engine wouldn't be up to temperature for half the journey which wont help. I know half a dozen people near me with DPF problems due to that kind of commuting around rural galway.

We hear that people "don't do the mileage for diesel" all the time, but it's about journey profile far more than mileage. If you have a diesel and do exceptionally low milage day to day, and even one long trip in the summer, you may never have a problem in a diesel.

What I would suggest then is refraining from further comment here so that you don't prejudice your position pending that advice and how it dictates your next steps. On the face of it, you may have a very good case.

Bad enough to have to do a 150km round trip to dealer but next nearest is double that at least.

Both Nissan and Mercedes Dealers should be familiar with that engine. The cost of 1 hour of diagnostics would be worth it. Also if problem persists get an ODBII reader and see what the car itself is communicating to you.

Unfortunately not, the ECM will not allow the vehicle to regenerate unless the speed is kept at a constant.
A motorway run at 100kph on cruise control, car kept in 5th gear would help if there's lot of soot build up.

Unfortunately I'm a good 1 and half hour drive from a good motorway so by the time i get back home the regeneration lights will be back on ðŸ˜œ

I can assure you that if anyone on this thread had to take their car to be fixed as many times as you have (and had it back with dirty seats) they'd not be best pleased.

There's an issue somewhere. Your driving sounds very normal. I have a ton of neighbours who don't drive their diesels 'correctly' without any issue.

It sounds like piss poor form from Renault but they have form for it.

No, he has a valid point.
A high quantity of bad driving habits will definitely be less harmful than a low quantity of bad habits.

800km a week on N road where the car is accelerating and slowing constantly is much worse for the dpf then popping to the shops once a week.
It is generating more soot and the car is not being driven in the correct manner to regenerate.

The OP needs a petrol, hybrid or electric vehicle. Diesel will not work for him with modern emissions standards.

If you're not doing that, it's down to you.

However, you should be really angry at the state of the car. Inform them you'll be having is professionally cleaned and the invoice will be sent to them. The have a visit to the show room to discuss why you were miss sold a diesel engines vehicle when it is the wrong type of car for your needs.

Accidentally

06 Clio some years ago. Random electrical faults that Renault never go to the bottom of. Never, ever again.

Had numerous Renault's. Never a problem with them tbh.

I'm not saying you're to blame, but 50km is a short journey for a diesel. That would be 30-40 minutes on N Roads.

That kind of driving is bad, it's high cumulative mileage, but never actually gives the car a chance to heat up and do a full DPF regen cycle.

People think the granny doing 20km per week is bad for a diesel, but in that case, the regular milage is so short that the DPF never actually gets full, before a long journey this done.

I had a Megane before this and never an issue. 1.5dCi
Koleos is 1.6.

It is just that the customer service is so shockingly bad that I will never buy another Renault.

My Renault dealer was excellent. Maybe that is where your biggest problem is which was hidden by the reliability of the Megane.

Believe me, I do. I would not be shy of pressing the accelerator.
I do almost 800km a week and the car gets a good long runout every time.

After the debacle that was the electric window regulators in mid 2000's meganes, I'd never go near another Renault. The reason is that Renault never bothered providing a proper fix. Some people got free replacements under pressure from Renault, but as it was a design fault, it kept re-occurring so pointless.

Maybe their newer cars are better quality, but no evidence of their customer focus to redeem themselves.

I've had no windows regulator problems on the 3 Renaults I owned in the last decade.

The 1.5 litre dCi has a very good reputation.

If your journeys are consistently 50km then the DPF should be regenerating. If you're mixing it with a lot of short spins then you're gonna have issues. If you're not getting satisfaction from the dealer then try another main dealer or contact Renault Ireland.

Shortest journey which would be rare would be over 5km

I contacted them over a week ago about the condition the car was returned and they are still waiting for a response from the dealer.
