• Nissan Micra K11 1L - Throttle body circuit function? 17 Jan 2011 (Forum)
  When the temperature gauge reached roughly 1/3 of the full scale, upon acceleration the engine would be starved of fuel and would jerk violently. The engine would idle roughly but the fault occurred mainly when the accelerator was pressed. I solved the issue by resoldering all the joints on the throttle body circuit board and now I'm curious as to what the circuit actually does??

• BMW 5 Series E60 - 520d Msport autobox judder 7 Nov 2010 (Forum)
  The usual elementary checks were made. filters, injectors, compression,glow plugs,etc and all was ok The local BMW dealer kept it for two days during hard weather leaving it outside, and said the problem was in the Dme control unit that manages all the fuel and air settings.  This was replaced and it went away for a while. But now its back and this time they are looking at the autobox torque converter.

• Legacy or Passat - Estate car buying advice please - Subaru or VW? 11 Oct 2010 (Forum)
  Typcal journeys weekly are short but then every couple of months there is a 500 mile round trip (no trailer) to consider, good fuel economy is therefore key for us. With a budget of up to £16/17k or thereabouts, we've narrowed it down to a Subaru Legacy Spouterourer (2.0 diesel - probably the 2008 model) or a Passat Estate (again, 2.0 tdi 170 PS) any thoughts/considerations/experience from you would be gratefully received.
• Ford Fiesta Saloon 1.25 Zetec 1996 model. - Damage to Engine Following trip to France 2 Oct 2010 (Forum)
  There are articles about the petrol being corrosive and damaging metal tanks and pipes but not to the engine. Could the valves have been damaged? Would replacing the fuel filter if I could find it, be worth doing?

• Ford Mondeo Ghia x 2.0 Petrol Duratec Engine - Where is the EGR Valve on a Mondeo? 20 Aug 2010 (Forum)
  I recently bought one and it judders and jerks at low revs around 1000 - 1500 revs. I have been told that a new air filter, new oil filter, new fuel filter and an oil change should sort the problem and it should give more MPG - I am only adveraging around 23MPG. But I was also told that it is worth cleaning the EGR valve. Thanks

• Electric car heaters - will we be warm enough? 10 Jul 2010 (Forum)
  There's lots of stuff in the press lately about electric cars, some with fuel engines to charge them up or drive a generator, some without.  I've never seen any mention of the heater, though - which for oldish thin me is the most important thing of all for most of the year.
• Ford Mondeo - Speedometer drops to Zero - once on every journey. 11 Jun 2010 (Forum)
  The mileometer also stops, the car loses a little bit of power, and the volume of the radio suddenly drops. My fuel warning light is NOT affected, and nor is the rev counter. Also, it is not an intermittent problem (i.e. probably not a loose or poor electrical or mechanical connection) because it happens JUST ONCE on every journey from cold, and always after about 4 miles of driving.
• Nissan Navara 2.5 - Nissan Navara 2.5 which is failing to start 12 Apr 2010 (Forum)
  Hi, I have a Nissan Navara 2.5 which is failing to start, the engine turns over but there is a stored fault code "E1 NATS Malfunction"  I suspect the immobiliser unit is not picking up the transponder signal from the key or it is not signalling the engine ECU with the correct information? (Faulty Immobiliser)  If the car has a fuel cut-off solenoid at the rear of the injector pump is there a way of energising this to (allow operation) from the wiring into / out of the PCM/ECU?  Is there anywhere I can download a wiring diagram for the car, Engine Electronics, ECU (PCM) and immobiliser unit?
• 1997 Volvo V40 1.9 TDI - Noise at low revs 6 Apr 2010 (Forum)
  I have confirmed that no air is getting into the system before and after the pump by splicing in a small piece of clear pipe. Could it be a problem connected to the fuel system or should I concentrate on the engine internals?   Thanks   Stewart

• Why diesels are better..... 22 Jan 2010 (Forum)
  A snippet from an article I just read about diesels: "Diesel engines function differently from petrol engines. They do not have complicated electronic fuel ignition systems. This eliminates the potential for failure, and improves reliability, reducing associated repair costs." Now correct me if I'm wrong, but from what I am hearing diesels are now very much more unreliable than petrols.
