Just bought new Leon mk2 diesel fr, couple of questions....

[MisterMoleyMole]

1 .. Car seems to be holding it's revs at 1000rpm on the dot whilst out driving. Normally ticks over at just over 500. It's like the tickover speed when you stop at lights etc is getting stuck and not dropping back to is right /idle speed. Any idea what the prob is there? Also sure it's not ticking over as smooth as I would expect. I can feel it popping or missing slighty when it's idling.

2 .. When driving it hard and you release the clutch quick the clutch pedal seems to stick about half way and then release instantly. It's a weird feeling I'm not used to on any clutches in cars I've driven before. Is this normal or is there an issue?

Look forward to hearing from some of you guys in the know.

Many many thanks in advance

1. Is probably the DPF (diesel particulate filter) regenerating. I.E the exhaust system is cleaning itself out from all the built up soot and should return to normal. A good run normally sorts it out.

Really? I seem to be able to force it back to normal revs by almost stalling it? In a 20 mile round trip it happened a few times... Is this what you would expect?

It sounds like a regen.Next time it happens take it for a drive for about 20 mins in 4th gear at 2500 rpm.It should sort it.

As for clutch sounds like there may be a problem there you want to get it checked out.

 

[dannychapman10]

Stoping and starting the regen process can force the car to have a hissy fit and will throw lights up on your dashboard which will subsequently require it to go to a dealership to have it manually cleaned, the regen can last sometime especially when driving round town, so go on a long run and it should settle down.

1. Most certain a Regen - let it do it! or you will be in trouble

2. The clutch is meant to do this. It has a release damper on it to stop you from damaging this clutch by just dropping it. Learn to drive it properly other wise you will end up with a big bill

1 is probably a DPF regen, there is plenty of info about your DPF in the owners hand book or by doing a search on here.

2 could be the carpet mat cought on the clutch pedal, I have had this exact issue before.

Some DPF info for the OP.>>>>>>>>>>>>>


There are 2 types of regeneration, passive and active

During long motorway journeys, passive regeneration will occur. This needs no intervention from the engine control unit. Due to the raised exhaust temperatures on a long journey
(temperatures between 350 and 500°C), the procedure occurs slowly and continuously across the catalytic-coated (with platinum) DPF. The catalytic-coated DPF is situated
close to the Engine, therefore the exhaust gas temperature is high enough (500°C) to ignite the soot particles.
Due to this soot is burned-off and is converted into a smaller amount of ash.

Active ‘regeneration’ is when the ECU intervenes when the soot loading in the DPF is calculated to be 45%. The procedure lasts for about 5 – 10 minutes. Specific measures are taken by
the ECU to raise the engine exhaust temperature to above 600°C, these include switching off the exhaust gas recirculation and increasing the fuel injection period to include a small
injection after the main injection. The soot particles are oxidised at this temperature.

The ECU will trigger a regeneration process, if for some reason this is aborted, ie. customer slows down, stops etc, the process will be resumed when
regeneration conditions are once again met, above 60km/h (38mph). This will continue for 15 minutes.
If after 2 attempts of 15 minutes, a successful regeneration has not been possible, the loading will increase. At 50% soot loading, the ECU will continue to
maintain maximum exhaust temperatures of 600°C to 650°C to cause a regeneration process. The system will try to run a regeneration process for 15
minutes. If unsuccessful, the system will repeat this process for a further 15 minutes, if still unsuccessful, the DPF light on the driver display panel will then be lit.

thanks very much all

...also thanks very much to the poster telling me to learn how to drive. Ive been driving for 14 years and am yet to have a clutch or gearbox go yet or any major problems relating to the clutch or gearbox so im not sure i'm doing too much wrong

^^^^^What do you expect from someone in Durhum..............

 

[MisterMoleyMole]

Just out of interest.... does this mean driving my car steady is bad for it?

Yes, They need a Good drive

person who tell You how to drive mean learn how to drive car with DPF in it as this can save You lot of money and You will be headache free lol

Yup! have had experience from a DPF car and if you don't abide by the rules then your in for some fun.

Just pointing out the fact you must be just releasing the clutch as quick as possible and these cars don't like this type of abuse. You also may have been driving cars for 14 years but dual mass flywheels are more common these days and dont take the abuse like standard single mass fly wheels. Next time I will keep quiet when any one else who is inexperienced with a car that I have owned for over 3 years now

^^^^^What do you expect from someone in Durhum..............

Your point is, jealousy will get you no where

Sorry dude reread your post and in haste I missed the 'it'. I read 'learn to drive properly'

My bad

And your point Nath?

Great info on the DPF BTW
