  in traffic as soon as the road clears the gauge goes back to normal or sometimes slightly lower than normal.

  think Ive tracked it to pot1 as when it happens pot 1 has a brighter flash down the gunson colour tune. Im struggling to work out what it is.

  weeks and had trouble getting it going when he came back, had to take the battery off a couple of times before it would start and run. At idle it occasionally misses, but a couple of times it just refuses to respond to the throttle, usually coming back after a moment or two. I wondered about coolant

  switch was for, about 30-40% had no idea what the air-bag failure warning light was and a similar proportion couldn't identify the coolant temperature gauge! The mind boggles.

• 306td...no ignition?? 29 May 2004 (Forum)
  fuel through as the glow plugs get damp if you crank the engine by hand. The glow plugs have been checked and are glowing as expected. There is no pressure coming back through the coolant and you can here it 'popping' through the exhaust as it is turned over. The fuel pump has not been disturbed so
• Spurious VW leak 9 Oct 2003 (Forum)

• Any water-cooled, probably, though its complicated - Sonax Radiator Rust Preventer 23 Aug 2019 (Forum)
  Be replacing my coolant soon, since I had to do an emergency top-up with flaky water from a hose, and I will lose some more if I get the temperature sensor out for testing. Seems stuck. I could only get cheapo green stuff with Chinese writing on it last time, from RT-Mart, and I’m

• Vauxhall Corsa C - Hissing sound under the bonnet 18 Dec 2016 (Forum)
  thing happens when I brake and as soon as I ease off the brakes, the sound comes back. The brake fluid, coolant and oil levels are all fine so I'm suspecting it may be a burst hose? The engine check light has come on as of today and luckily enough the garage that I got it from is willing to sort it out
• Nissan Qashqai - Prang - damage not immediately obvious 2 Dec 2015 (Forum)
  My car's EM light came on a couple of weeks ago - AA said it was a DPF issue. Tried regeneration the DPF myself but no joy, so took it to the garage. Garage have now discovered a damaged intercooler, leaking coolant (and leaking AC) afftecting the turbo, which is likely why the DPF

• Diesel or petrol... can't seem to decide 26 Jan 2012 (Forum)
  prayers (fuel cost wise) but I'm being scared off Mondeo diesels with stories about the DMF and turbo problems. I have driven a Rover 220 SDi before and never had a problem with the engine components (always electrical). The coolant cap was left off for quite a while and it didn;t miss a beat. Ran
