  to 2000rpm and then above 2000 it suffered sever juddering. I gave up and called the AA who recovered the vehicle to the dealer.

• Renault Espace (1997 - 2002) - 99 2.0 Autobox, either repair or change to manual? 13 Sep 2009 (Forum)
  should be in the right place. I can find a doner car for the pedal set, cables etc. I can find a decent manual 5 speed box. I can find the dash replacement trim to change from the auto shift. Has anyone done this before? I am concerned about certain requirements. I think the box and ECU are related

  the car will just suddenly loose power and will have to put the throttle down heavier and its all fine again. The clutch seems fine.

  it's started it still drives fine though. I've had the ECU fault codes read, then reset, then the light comes on around 30miles later. I paid 170quid last week to have the EGR valve replaced, as this was on the fault code. Within an hour, the light was back on, so I took the car back to my local

  various things sorted including; - Water leak in spare wheel well. - Poor fuel economy/sluggish acceleration (fixed by updating ECU). - Faulty CD Player (replaced, still faulty). - Bits of trim falling off. In my opinion this is bad enough, however the biggest problem has been the boot catch which
• Renault Megane (1996 - 1998) - 96 1.4 (8v) Failure to start after running fine - 5 Aug 2008 (Forum)
  at it intermettently. They reckon it was caused by a battery not at its peak (unlikely as it's only about a year old), and found some fault codes in the ECU which they cleared & it was then OK. Similar thing happened on saturday - wouldn't restart after being parked for 5 minutes. Turned over fine but wouldn't fire

• Pug 205GTi 1.6 - Low tickover & cut out. 27 Jun 2007 (Forum)
  ?t affect it, nor does the stereo of the changer, or the satnav plugged into the lighter. I?ve had the alternator tested and its perfect, I?ve also had the ECU plugged into a diagnostic, but it cant be read, which is disturbing, the diagnostic just says to turn the ignition on - when it already

  that the acceleration its slowly. After the EML pop up the "P1125 - Critical System Malfunction 2" is stored in the ECU.

  1994 306 1.8i SR Sedan with Magneti Marelli 8P ECU. Whilst curing a pinking problem (see separate post) I decided to cure the slightly hunting idle and ease of stalling when coming off idle to drive away that has developed gradually over the past year. Everything pointed to the idle control valve
• Focus TDCi smoke problems 25 Aug 2005 (Forum)
  quite such a bad repeat of this trick on the way in. I spoke to the mechanic there and we reckoned we would be wasting our time taking it out if it wasn't smoking so he said give it a week of your own driving and see what happens. If I'm not happy he can then update the ECU with all the latest codes etc
• Focus 115 TDCi 9 Mar 2005 (Forum)
  for nearly a week and they phoned me today stating they couldn't replicate the faults for long enough to get a fault code on the ECU.

• rover 216 cutting out & erratic idling 12 Dec 2004 (Forum)
  and they looked at the ECU which reported that the temperature sensor was faulty. They claimed that this is a common false reading so voided the error.
