• small economical run about ?diesel? 14 Oct 2005 (Forum)
  Which it will, so she has to go. What I need is as per header, smallish hatch with boot space & dead economical to run. Will be used to commute to work too, so thinking about it so much of a run about then. What I'd like is one of those wee fast diesels that have arisen & looking through back threads I see the Seat Leon seems a better bet than the Ibiza.

• Vauxhall Corsa D 2007 1.3 CDTi - Engine doesn't pick up and runs rough 3 Dec 2014 (Forum)
  So I was on my own, first I changed the air filter and then the diesel fuel filter, this made no difference. Further searches on the interweb on rough running engines seemed to point to the Mass Air Flow (MAF) unit being at fault, this unit measures the air flow into the engine and sends the relevant signal the the engine's Engine Control Unit (ECU).

• Ford Fiesta (1995 - 1999) - 1997 1300 Noisy engine and slave cylinder issue- n 19 Feb 2009 (Forum)
  Again its been like this for ages. There is also a thick black ring at the tip of the exhaust so I assume it is running rich. I've just had the plugs changed so its running a lot smoother now, it was mis firing before it still does a tiny bit but its hardly noticable. Would I right in thinking that worn plugs would cause it to run rich because of unburnt fuel?
• Diesel, Cold, stop start fuel consumption figures 20 Dec 2007 (Forum)
  (Diesels driven care that is and not booted forward at every gear change with maximum torque) Could it be that the official fuel consumption tests flatter Petrol? and what would the difference be if the typical short, still not up to temperature run above were introduced as a measurement? where Petrol has to run rich and waste its fuel.

• Silicon grease on brake slide pins 6 Dec 2022 (Forum)
  Can someone point out what I am failing to appreciate. Brake slide pins are metal running through synthetic seals and the recommended lubricant is silicon based. Spring powered air rifles have a synthetic seal running within a metal cylinder and should never be lubricated with a silicon-based lubricant.
• ford galaxy 2.8 v6 - Alternator 13 Oct 2020 (Forum)
    also fitted a new battery and secondhand alternator but don't think it is charging as when i attached a volt meter it is reading 12.15v when engine is not running but 11.95v when engine is running.  also car is ticking over at 1000rpm and climate control is not blowing when i turn up blowers (don't know if linked).  if alternator is at fault is it just likely to be the regulator.
