Really? Does yours or anyone elses? What's the cause and can you fix it? It's so annoying when you're just cruising dine the motorway

So it's been a over a year and I still have the whine!! Thought I'd give it a bump, see if anyone new can help me out. Same as above really, when the throttle is hardy open just cruising it whines. Only fix I've found so far is turn the radio up! Thanks

So just left it 5 mins while I wrote the bit above and both rad pipes are hot. Top left and bottom rad to thermostat. So does that mean both thermostat and water pump are working fine?

Other thing I forgot to mention whemnthe car got hotter is seemed like the fans got a kick up the arse and span faster. Are they multi speed?

I guess any excuse to spend money on something new is good lol, just wanna make sure what part it is. So I just got home and started it in my garage, the drivers side fan came on fairly soon. I left it a while and the second fan came on. I unscrewed the bleed screw and coolant did actually come out this time, along with a load of bubbles. (aa man tried this on the roadside, however he left both rad cap and bleed screw off And nothing came out of the bleed pipe). At this point the heater did not work. I left it a little longer and did the same thing to the bleed screw and I repeated this 4 times in total. I never tool the bleed screw totally out....should I have done??? Now heater is working great. The top left rad pipe was really hot (about 75°c, however the bottom right rad pipe was still cold around 35°C. I used a laser thermometer to get the temp. So in a way I'm no better off, do I still have air in the system? Should I just bite the bullet, empty the rad, remove the thermostat and stick it in some boiling water and see if it opens?

Thanks for the reply guys, if the fans don't work do you have them in stock Alex?? Is there a back or method to bleeding the system? I heard it is a bit of a pain. Thanks

Hi, hoping for a bit of advice/help. Car has never overheated whilst I have owned it. It was 27°c yesterday, may car had been sat for 8 hours. I got in to drive home. Going through town at 30-40mph. Got approximately 5 miles, around 12 mins driving and the engine management light came on, it juddered like hell and had no power. I pulled up and it smelt hot. I could hear a hissing/whinning noise. Opened the bonnet and coolant was coming from the header tank. Header tank was now empty. Waited for it to cool down. Topped rad up with water and nothing came from bleed screw. Topped up bleed screw and water came from rad cap filler hole. Drove home and left it. I'm thinking.... 1) blocked rad 2) thermostat 3) water pump 4) air in system 5) head gasket!!! I had a p1217 code Any help would be good. Thanks

Yeah I'm certain it's got to be something to do with the throttle body or Induction. It only ever happens when the accelerator pedal has very little pressure. Like I said put the pedal down a bit more the noise goes, take you're foot off the pedal the noise goes. I had a new bank 1 sensor fitted and he smoke tested for leaks so I don't think it'll be induction or exhaust really. I commented on a post about this 3 years ago when someone had a similar issue. He didn't find the cause then and I've reached for ages and not found an answer. You would've thought this problem would've come up before on other people's cars and the depth of knowledge on here someone must know. If I ever get to the bottom of it I'll post the answer

Afternoon all, as I was going to japfest and had a 135 mile journey there o decided to change the rear whining wheel bearing. Pain in the backside but it was sorted. However I have another whine and it's just when you press the accelerator. So basically when the throttle is only just open. So floor it no whine. Let off no whine. It's only when the throttle is very slightly open. Also happens on cruise control again when the throttle is slightly open. So that was annoying on the journey down. So what is the problem and how do I fix it????? Is it a throttle body bearing? Is it a common problem? I know the noise has always been there but just want it sorted now.
