I don't fancy the airbag going off in my face!!! Cheers Rob

• hot wiring 24 Jan 2003 (Forum)
  I want to start my Dutton (which needs a new loom) by bypassing the ignition. I have provided a + and - to the coil direct from battery, then turned the engine over using the starter. I am not getting a spark from the HT leads? Does the body of the coil need an earth? Is it a live or earth wire which goes into the distributor? Thanks Ste
• radio code 11 May 2002 (Forum)
  Does anyone no how to reset the code on an old radio cassette stereo? I recently had problems with an alarm and had to disconnect the battery, hence prompting the radio to ask for the code, which I don't have as it is a second hand car. The stereo is not factory fitted and therefore I can't ask the manufacturer. The car is a rover 218 sld 1993. any tips ??

  Does anyone know if there was a modification on Citroen diesels to replace the filter asembly and primer on the side of the battery housing.I have a 2.5TD XM which has had an inline Bosch filter fitted and the assembly removed. This was done by a Citroen dealer but another doubts the move. Car is a 1995 VSX estate and there are no problems with the inline arrangements.

• Anyone bought a used tesla? 31 Dec 2023 (Forum)
  I know there are more sensible options but I think the joy I'd get from the car is worth a bit of extra money and the risk of financial oblivion if the battery dies. My max budget would be £30k but I've seen older model 3's for less than 20.

• Volkswagen Golf Est Diesel Auto 2011 1598cc - VW breakdown 14 Aug 2022 (Forum)
  Left the car with the garage. They ran computer diagnostics but can find no fault. Battery tested and perfect. Spoken to other garages but no-one can tell me what the fault is, why it happened or whether it will happen again. Last garage told me they couldn’t diagnose an intermittent fault if it wasn’t in progress at the time.
• Electric Car (EV) Interior Heaters 1 Dec 2020 (Forum)
  My question is how does the interior heater of an pure EV work (Not a hybrid)? Does it use the car batteries? If so, it would surely have flattened the batteries shortly after being stranded leaving the occupants freezing (or dead) and leaving an non-driveable vehicle needing recovered. Or does the heater work of petrol or diesel?

• Kia Niro Plug-in Hybrid - Plug in Hybrid - a few real time statistics. 23 Sep 2019 (Forum)
  Take out the battery running, the HEV consumption is working out at 64mpg. I don't think that is too bad. Just shows the WLTP figures for plug-in hybrids are, at best fictitious, at worst very misleading. So, perhaps the declaration of mpg both in 'real mpg' in the HJ column and those given for official purposes should now give a split of this sort

• audi A3 sportback hybrid - audi A3 not moving 14 Aug 2017 (Forum)
    any ideas of what to do? or try? My guess as of now, is that even thought it says the eterno battery is almost full I am thinking there is a misreading somewhere. So, I thought I will unplug the battery to see if the system resets and it works but I am afraid I will screw something up by doing this.
