Seems slow..

[stefan]

OK guys serious dilemma here. May sound weird. When I first got the car, I was blown away with its speed. Now either something has mechanically happened to it, and its now slower.. or I have somehow got used to the speed and its no longer enough..

Anyone else feel like this? Is it really that pronounced.. that fast? 500km in and I could swear its slower :P...

You're probably just getting used to the power. The fix is of course easy. Start modding!

[Brandon26pdx]

Did you put cheap gas in it?

The dealer may have put cheap gas in it too if they gave you a complimentary fill up...the ECU learns over time to dial the power back if it detects the fuel octane is too low for a prolonged period. The car may have started to feel slower as you burned through that first tank?

[stefan]

No I'm on my second gas of the highest octane available up here (91)

Try timing 0-100 yourself and see if anything changed.

[Brandon26pdx]

Has the weather been significantly warmer since you first picked it up?

Are you pressing the pedal all the way to the right? :biggrin:

If yes, push harder:wink:

Do you carry 3 passengers along with yourself? If yes, I suggest having "seat ejection" installed for the passengers. You can save some money if you forego the safety landing parachutes.

Mine has felt even faster the more miles I put on it... it's easy to figure out.. have someone time you with a stop watch... run it 0 to 60 a cpl times..

Silly as it may sound, if you notice significant speed reduction, take it to your dealer. This has happened to a few 335i's, and the fix was a new turbo.. Can never know for sure without diagnosis.

I would tend to agree with this. If you've got a good feeling that it's not just you getting used to the car, then something may be wrong. If thats the case, its at least worth the $200 diag fee if it turns out to be nothing.

We secretly switched your 135 with a 128 to see if you notice. June 1st is April fools day in Canada. :biggrin::biggrin:

In my opinion (and this works with anything, not just cars), if you notice something...there's something TO notice. Our senses and eyes are trained to except daily routines and when something changes it even in the slightest way, we notice. So...while you may get used to the power you only notice a difference when there's something different going on!

Just my two cents. Or sou or cenne or whatever you freaky half french people call it up there.

You probably got use to the power as I am pondering Dinan myself now. Dan has a good point, if you genuinely feel the car is having problem then take it in.

I, too, side with the becoming accustomed-to the power/torque theory, I did the same thing, was out of the car for two weeks as it has been raining here in the PNW, got back in 'the thing' today, clearly, it is not down on power, oh no. Your car is quite likely just fine, perhaps you should be looked at.:wink::biggrin:

[jbenington86]

hahaha that would suck....getting a car that looks 100% like the 135i but didnt have the turbos.....hmm wonder how much work and $ it would cost to make a 128i look exactly like a 135i could rasie the value when selling hehehe im so shady

[theanhdy]

That's weird, my car feels faster at 700 miles than before.

Yeah but all you wld have to do is drive it to know if it is a 128 or a 135...

700 miles is about the time my car loosened up, felt more responsive, mighta' been me becoming accustomed to the thing as well.:wink:

[Citizen Z]

My car definitely feels slower having taken it on the 'Ring. And its not because it actually IS slower, its just that once you've taken your ride out for a flogging, EVERYTHING feels slow.

[BMW135iCA]

I would say either getting used to the power or something may be wrong. For peace of mind you may want to have it looked at.

You know what.. I just might. Today I started it and it felt like it was going to shake itself apart.. Sort of like when only half of your spark plugs are firing (you get that deep, rumbling sound). Power was essentially gone. Fixed by restarting the engine (do 135s run windows?)
