  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

  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

  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

• 1994 BMW E36 M3 - White smoke (over fuelling?) 22 May 2010 (Forum)
  RAC bloke on his break, I used rad weld. Does anyone have any ideas? If it's an air leak in a pipe, wouldn't that trigger a code? I've been told the rad weld could have caused problems with my coolant temperature sensor (and even damaged the heads), but the car has never overheated and I'm
