What's the problem with it mate,

Speed dropping?

[dezwez]

Hi welcome :)

[silversmith]

I'm needing some help with a crusie control issue that has developed recently. Ford focus mark 2 2.0 tdci.
It surges or pulses as if the brakes are being pulsed while at the
cruisng speed I set. A bit like driving through lines of treacle. It
only happens when trying to maintain the cruising speed. not on
throttling up or down using the steering wheel controls. Ive had it into
to the ford dealer who are perplexed. It's not showing up any error
codes. However i have had the EGR replaced and the fuel filter
changed in pursuit of the problem but it's still there. Does cruise
control apply any braking if you run over the set cruising speed? say
going down a steep hill is it applying braking I'm asking my self? Where
are the sensors for the cruise control? where does it get its info from
for mainting a constant speed?

Any help you can give me would be appreciated.

Hi mate,

Firstly on a separate topic non cruise control related recommendation: id blank that egr valve with a stainless steel blanking plate.

Now on to your cruise control,

The sensors are fitted to all focus models weather they have cruise control or not,

The cruise control doesnt use the brakes but there is a sensor in the brake pedal which is used to deactivate cruise control when pressed,

Ford could try re-calibration of your accelerator pedal

Restetting its parimeters

Question:

When its set to a speed on cruise control

And it begins to slow

Does it speed up again by itself?

It doesn't really slow. it stays at the set speed but its judderry

[silversmith]

It doesn't really slow. it stays at the set speed but its judderry

Also what benefit would i gain from blanking the egr valve. thanks for your replies.

Ok

Are the revs steady on idle,

And does it only jump when on cruse control?

You could try changing throttle pedal which contains the sensor inside it,

No gurantee it will fix the problem though.

Cruise control records the throttle position sensor (TPS)

When you press "set"

Cruse control maintaions that position of throttle by itself

You could also try de-activating and re-activating cruise control on the GEM yourself using a modified ELM327 diagnostic tool and the elm config software from the forum here,

People use it to fit cruise control to there ford,

Because all models have the sensors,

People just need the 4 spoke steering wheel and cruise control buttons they then activate it using the elmconfig software

The revs are fine at idle. its only a problem when using the cruise control. i had a wee look at the thread on elm config software. food for thought. Im annoyed as cruise control was fitted from new and only recently developed this glitch! You have already been more informative than my garage. I'll need to have a word with them I think.

No prob mate,

Im a long term member i enjoy the forum and creating guides see my profile page by clicking on my avatar picture 30 guides to date,

The egr valve recirculates up to 20% of exhaust gases back in to the induction chamber where it is sucked in to the cumbustion chamber,

This brings excess carbon in to your engine excessive oil contamination leeding to carbon build up in the oil creating restriction of oil to the turbo,

By blanking the egr you prevent waste gas Recirculation,

The engine will only suck in clean fresh air,

The flow of exhaust gases increases by up to 20% across the rev range

As result your turbo spool time is also reduced

Thus making your car more efficient on fuel,

Oil stays cleaner with a reduction in contamination

Your dpf (if fitted) will be cleaner due to increased exhaust flow

See more positive feedback on my guide:

http://www.fordownersclub.com/forums/topic/42915-guide-fitting-egr-blanking-plate-16tdci-engine/

My focus is a 1.6TDCi DV6 Euro 6 emissions

Ive blanked egr valve, gutted dpf chamber, remapped fom 90-125bhp

Text book turbo failure on the 1.6TDCi is around 80-100,000 miles

Im now at 150,000 on my stock turbo and its mapped yo!!

Thanks to EGR blanking saving me a turbo

No prob mate keep us posted,

The throttle pedal naturally gets the most use,

It has the TPS (throttle position sensor) attached so i have a feeling the sensor is failing due to wear and tare which i_ sending false readings to the GEM causing the jumpy sensation,

Re-calibration of its parimeters may do the trick rather than changing the pedal if it is the culprit,

If changing pedal unit: contact breakers because all focus have same unit weather cruise control is fitted or not they all have the TPS attached, ford then added switches to those enabling cruise control.

If you would like a loan of a modified ELM327 i loan mine out for a fee of 9 GBP via PayPal to cover shipping to you,

I provide a self addressed envelope with an address within the uk for you to seal and return when completed.

Its an option if you dont plan on purchasing one yourself however the cost of \ modified ELM327 has come down alot since the time i began loaning out mine,

Ford garages are not very helpful mate,

There all the same, i dont even use my local ford dealership anymore,

For me the car is a hobby so im big in to it and being on here almost five years every day,

Ive learned alot about the focus 2005-2011 model mk2 and mk2.5

Thanks for all that lenny. Very kind of you to offer the cable. Maybe when im a bit more confident in what i need to do ill give you a shout.

No problem atall mate.

There also available to purchase for 15 pounds including shipping from here:

Actually works out cheaper than me loaning mine out to anyone in the uk now lol the price is dropping all the time with these units,

Always happy to help mate and i hope the issue with cruise control doesn't destroy your love for the motor. Hopfully it gets fixed soon.
