How to get around my bust Jetta key?

I have a 2007 Volkswagen Jetta and the key is very temperamental. Sometimes the boot opens, but generally not. I can’t find a manual way of opening it.

Any suggestions?

Safest way to jump-start a car?


In advice on how to jump start a car, you are usually advised to attach negative cable to bare metal, away from battery, of flat car. This advice is not given for the donor car. This advice is stated to be because "hydrogen gas can build up above the battery itself, which could be explosive." But if hydrogen can build up above the battery, why are you only advised to attach to bare metal on the "flat" car? Why couldn't hydrogen gas build up above the "donor" car battery? In any event, surely once you open the bonnet, the gas, if any, would dissipate fairly rapidly?

Thanks Philip

What's up with my Honda Civic's stop-start?

Hi, I recently got a new battery for my 141 D Honda Civic, but the auto stop function is not working correctly. I asked the installer and he said it is installed correctly and auto stop won't always work. Please clarify.

Kind regards, Kieran O'Brien.

Should my Polo's stop-start be working cold?

The stop-start system on my 2019 1.0-litre petrol Polo is enabled with a stone cold engine: if I drive 100 yards after a overnight stop the stop-start is enabled. This can't be logical as the diesels all have to reach temperature before enabling it. Spoke to Volkswagen, but can't get a straight answer. I have also driven other petrol Polos and they are exactly the same.

Lots of issues with my Mercedes GLC...

In my Mercedes GLC, the stop/start system is not working. Also, the radio is cutting out and the reversing camera is not working after stopping and turning off the car on restart.

Any one else have these problems?
