135i Software update/version question

Si-135i · 07-08-2008, 06:32 AM

I have read many posts about a software update being applied to the 135i and the 335i to stop waste gate chatter and as a result of the some turbo lag is produced, mostly in 1st gear pulling away. This apparently is an ongoing issue to which there is no final remedy yet, but some people have had the old program put back on as the car does not drive anywhere near as spirited with the remory fix. Is this a problem in the UK or just for our friends in the US ?

Also in the US there seem to be a lot of problems with fuel pumps failing and an upgade is being put in on a recal. Does this apply to the uk ?

Cheers,

Si

If if let the car roll along in 1st gear at about 1000rpm with the clutch fully engaged and then floor it, the real power doesn't come in till about 3000 rpm. In 2nd it seems nearer 1800 rpm. if I am at motorway speeds in 6th gear and squeeze the accelerator, there is the "feel" of the turbo winding up so it is not "instant" power but more of a surge.

Is the torque deliberately limited in first gear? That's often the case with more powerful engines. Or is the traction control reigning in the engine power?

I don't think it is traction control as the light doesn't come on. More likely 5000 rpm upwards in first for that. If I give it some beans off the line it will accelerate must faster so the limit of torque has definately not been reached when I do this.
