leon fr max speed issue

[josko]

Hi all, i have a problem and could not find an answer searching the forum. I have 2.0 tdi pd170 engine on my fr and have problem reaching speed above 210 km/h. As I am aware, normally this car should speed up to cca. 230 km/h. Mine comes to 210km/h and as it cut out in the same intervals too obtain the 210km/h speed. My winter tire setup is off. Is there any idea on what could be the problem. Is this related to low mpg? Thanks for any help in advance...

You will be getting low mpg if you are trying to reach the top speed


What a pointless thread

I presume that is while you're on the autobahn, track or private land as well?

Maybe you are changing gears too early which is why you can't reach max speed?

 

[josko]

My goal is not to drive in max speed but as i am second owner, wanted to check if there is everything as expected. My bad mpg was in normal town driving, and on open road (avg 90km/h), not on higways (25mpg). In 6th gear car reaches very easy mentioned speed but want pas 210km/h. I only wanted to establish if it is everything ok with the engine. I dont understand what is so pointless about it...

 

[josko]

I assumed there is maybe something wrong with MAF so bad mpg is the result, i understand that reaching max speed would bring me to excessive consumption...

In the UK, the maximum speed of the the PD170 is shown as 133mph or 214kph. Don't know if it's different in your country.

 

[josko]

in our country is the same thing, but as i know this car doesn't have max speed limiter so if it has power, it would be normal to achive higher max speed. In my case it seems that it hesitates to go above that speed. My 2004 Toledo with 1.9 130pd achived 220 km/h and I tought it would be normal for FR to go faster. I am afraid only if there is smoething wrong with fuel injecting.

think your car must be breaking, take it to garage asap. bad mpg at 210kmh an hour is very rare!!!!

The only thing wrong with it is your driving

I sense a Buzz thread here but I'll try and be serious for a min.

Josko, does your car hit the rev limiter in 3rd and 4th ok or does it drop power around 4000-4500 revs? You could be having problems with your etg's

 

[josko]

I didn't notice any rev limiter in those gears. I was shifting around 4000 rpm.

Sorry, but i do not understand what is the problem with my questions, and thread. I just try to pick up some information about the car, as in my country there are not a lot of those cars. what is the point of buying the car with 170hp if you are not interested what are his limits, also, here people do a lot of things to gain more power for those cars, and then i ask my self for what reason if it is so strange to try it. Also in Germany on highways there are no speed limits and i am offten traveling there so i have the possibility try my car there.

i am sorry but i do not understand what is the problem talking about speed on forum that is named after cars that are produced as fast and sporty. Maybe you should try to first understand my question and then be so ''friendlly''.

I think its a fair enough question. Bought a performance car, is wondering about top speed. Wouldn't want to risk it in the uk, but he isnt here so that anwers that question. Besides, most of us do succumb to 'pup stats'anyway. I may never achieve 140mph+, but is nice to know I can.

Anyway, just to be clear, you say the car just suddenly stops accelerating? Is there some sort of limiter fitted in you country? Seems unlikely, but you never know. The MG6 is limited to 120mph for insurance reasons, not beyond the realms of possibility that the leon could be limited to 210kph/130mph? Seems a nice round number.


Could it be poor quality fuel? I know using very low octane fuel (ron 90 or below) would seriously retard the timing in a petrol car, so could be done on power? Not sure if this actually applies to diesel mind. If not, please disregard!

Low pressure in the tires causing more rolling resistance and therefore reduced speed and mpg?

Egr issues, clogged filters or any other maintenance related issues could also affect the cars performance.

If none of the above, then I have exhausted my Sunday evening thinking power. In any event, i hope you get it sorted.

firts of all, thank you very much for the answer, and understanding.
as far as i know, those cars are not limited for our market but i also was thinking so because of the ''round figure'' (210). When I reach this number, car starts to pull and push in equal intervals obtaining that speed. It reaches that speed very easy not bothering small hills also (in 6th gear ofcourse) so it has enough power.

sorry for speeling...

In our Italian forum people ask the same thing, well I had a PD170 and was a supercar till 125mph, but really stop to push at 130/133 mph

They said that has a VI gear rev limiter..they said...

I don't know if it has any limiter but it's normal for PD170 quite and enjoy mate!

Answer about the height of your topspeed is quite simple, it's a pd and unless all the parts are in newlike state 210 km/h is about what it is.
The pd tends to get poluted rather fast and injectors will wear rather quick (a ultrasone cleanup might help but in most cases only new one will bring back the claimed power).
Seen too many 170 pd's loosing up to 30 bhp within a few years of use.
Recently I drove to Münich with some friends (I took my 178 bhp tuned subaru and he his tuned 200 bhp leon with pd) appeared that while accellerating both cars where equal the Subaru reached 220 (on gps) the Leon simple wasn't able to get past 200.
After that the engine had a dpf removal, egr delete, complete cleanup and new injectors and now it pulls much harder and reaches a much higher topspeed.

Thanks for the help and sharing experience guys. Now, after getting your opinions, I think my car is running ok. I only need to test mpg in normal driving conditions in city and at open road. I only did one full tank since i have it, in normal driving on open road and city (combined) I reached 30 mpg.

In that case it sounds like you're either hitting the rev limiter, or the car is electronically limited to that speed.

At what revs are you experiencing this pull and push intervals, im still convinced its your etgs
