Sorry, neither have PP nor am I near Bristol

What's happening? Maybe we can help diagnose the problem from the symptoms rather than the codes?

Hi Highlander

This one is slightly dangerous. I noticed my cruise control was not workng today then as i was going up a steap hill the car acted as i had taken my foot off the acc pedal and started dropping speed. To get it back i had to take my foot off the pedal and put it back on. I reset the BSI and went out stil no cc and still did it once or twice. So my in laws suggested going out for tea so parked mine up and we went out for an hour or 2. Come back and found that CC was working fine now, however got the same issue going up a hill

Cruise control deactivates when you press either the brake or the clutch. If you press the accelerator, the car will accelerate, and if you let go, the car will slow to the pre-set speed, so the accelerator itself can't deactivate cruise control.

This means that there is a microswitch on both the brake and clutch pedals. If the microswitch for either fails closed, then it would result in the cruise control deactivating either randomly, or immediately after every time you try and switch it on. Checking/replacing those switches would be a good start.

Should of mentioned that its an auto - to be honest CC dont bother me as this si my first with it my issue is losing the power even oon hills ( love in a hilley area) this is when im in control

Has the Engine Management Light come on?

Which engine is it?

[dave406]

no EML and 2.0hdi 110 02 plate when i finish work gonna unplug the MAF and see if that helps

Normally a turbo diesel will pull uphill no problems - its the best thing about them - but if yours slows down on a hill then I would look at turbo pipes to check for leaks....

Unplugging the MAF is a good idea, this will eliminate it as faulty if problem persists.

Wil ahve to wait til monday but upplugged the MAF and willgo for a drive in a second

[dave406]

Mad disconnected feels more responsive no eml just got to find a hill

[dave406]

Seems to ok with MAF disconnected but CC still not working will have to wait till i get PP am i right in thinking i aint got a vacuum leak if i pump the brake pedal and it goes hard and if i keep my foot on it it slowly goes down?
