Td5 hesitating at junctions........

(1/4) > >>

Jimbo:

The 110 is playing up, normal driving is fine, but when I go to pull away from a junction or roundabout it falters slightly - just as I start to come off the clutch and give it some gas. Doesn't do it every time, but when it does I need to 'tickle' the throttle to get it to go - and then it goes fine. It's almost like when a petrol engined car starts to stall as the tickover is a bit low - but the 110 idles fine.

The throttle is a fly-by-wire thing - there doesn't seem to be any flat-spots on the throttle pedal, and no fault codes have been logged in the ECU

I know there's some sort of electronic damper thing on the clutch pedal - to stop the engine from surging when you dip the clutch, could that be playing up ?, any other ideas ?

burgerman:
 Oil in the loom ??  Just a thought  :-k  ;)

Jimbo:
That thought had crossed my mind too - just need to find 10mins to whip the plug off the head and have a look !

burgerman:
 Just take the drivers seat and cover off and remove the connecter from the ecu, you will see straight away, takes 2 mins , you will only need to remove the rocker cover to replace the engine/injector loom, they cost about £40, did ours a couple of weeks ago, but by chance it was spotted before it caused any problems  :)

Jim,

Plug your Nanocom in...

Look in the live data section, and you should be able to see the brake and clutch switches  ;)

Also, have a look at what reading your MAF is giving at idle, it should be between 50 and 65 ish kg/hr.

At the same time, have a look at the MAP readings.  Give the Defender a rev, and it should move from 102 ish at idle, to about 114.  You can also check this on the go.... when you are making proper boost pressure.
