fault

The low coolant warning light is coming on in my Mazda RX-8 when driving over 120km/h. Coolant level and oil are ok. Any idea what's causing this? The light goes off again after a few minutes.

Hi, I recently bought a 2008 Kia Sorento (30k miles) privately and really like it. Everything has been great so far except for when I hit bumps in the road. The bang you get from going over bumps is quite hard and travels through your body. I did research on Sorentos before buying it but now going back I see there are suspension problems reported on Kias. Do you think if I replace the shocks it should ease the suspension problem and do you know if there is a type of shock that I should get a garage to install to try and dampen down the bang I get from bumps in the road?

Thanks Ciaran.

My 2006 Skoda Octavia 1.9 diesel takes ages to start in the morning. When it does start it runs all day without any problems. Is it injector related?

Having changed my spark plugs and leads my car loses power after about 10 minutes of driving. What could be the problem?

Hi. I just wanted to know how would I find out if my car's head gasket is gone. When I start the car heaps of water comes out of the exhaust, but I'm not that sure if it is the gasket. Can you help me?

Thanks

My Toyota Camry suddenly started leaking coolant from the radiator and the engine stopped. Any ideas why?

I recently purchased a 3.0-litre Toyota Landcruiser in Northern Ireland and have noticed some rust in the chassis and exhaust, but more worrying is a whining noise it has developed in first, second and third gears at around 2,000rpm - the noise dissipates at about 2,300rpm. Have you any idea what the problem could be? Any help would be greatly appreciated.

My BMW's injectors inject fuel all the time. What can be the problem?

Hi, I have a '98 Peugeot 306 CC with a folding electric roof. I'm having a problem when closing the roof. It opens perfectly but when it's closing the back window won't open to let the boot part down: i.e. it isn't completing the closing sequence. Could this be an electrical problem? Can you help?

I got the head gasket done on my 02 Honda Civic 1.4 last September (2010) due to burst radiator. Now it's gone again after nine months. Would this indicate it was not fixed properly or just bad luck?
