Top speed 307 sw hdi 110 pk

I'm driving a 110 pk hdi from january 2003. The top speed of the car as per
the specifications should be 185 km/hr. Driving with good circumstances (no
wind) the car comes no further than 175 km/hr on the instruments and when
you make an average on the board computer the maximum reached value is 169.
Is this normal? The car has 66000 km's and warrenty ends....

Kind regards,

Try doing it down a long hill, should hit the top speed then on the limiter

 

i have the same car... mine is doing easy 190 km/h on speedometer...
so if its lying it is about 185....

so maybe yours needs cleaning of common rail injectors or something...

 

air filter! the injectors don't need cleaning whatsoever

 

if you live in croatia they do ) diesel quality is poor here..

 

you need to clean your fuel filter, the fuel that goes trough the
injectors does so @ 1400 bar, giving that and the fact that diesel is
a nice cleaning product itself you can imagine putting some "injector
cleaning" stuff in wont help a single bit.

the OP is a dutchman, he probably uses quality fuel, and if not he
should do

apart from that he should use a good air filter like the standard pug
filter or a K&N replacement filter ( which turns out cheaper over
60.000 KM)
replacing fuel filters on a regular scheme is also to be recommended,
at least every 20.000 km even with good q fuel because one way or
another the filter clogs up with debris from fuel pistols etc.
failing to do so might choke the whole fuel system and i can tel you a
HDI pressure pump does not like that.

 

the ecu mapping is done so that it would even run on chemical
waste.... it would be advisable not to fidlle around with it when
driving in your country.

i dont know the BMC filters but i'm sure they work well, changing fuel
filters every 20.000 is a very good practice.... i wish the diesel
drivers would do that over here....

 

Oooops, time to change my fuel filter then, haven't done it in 52,000 miles!
