fault

I have a Nissan Micra that is a 2004 model; it's only done 40,000 miles on the clock and I have been told l need a new timing chain, which will cost me around £600. I am just wondering if it's worth repairing or am l better off buying a new but different car as l have heard there's a lot of faults with Nissan Micra and Note.

My speedometer keeping dropping to zero even when I am driving at speed. What do I do?

Hi, my 2007 Skoda Octavia will not start. It will turn over but will not start (had to jump start it the day before). What could be wrong?

Help or advice for 2003 Audi A6 please: front door not closing properly. Will close by being extremely gentle. Any other action leaves door not fully closed.

I bought a secondhand Opel Meriva (2005, 1.4) last year. Its history shows that, just before I bought it, the steering column had been replaced. There was a power steering "issue" last year (failure making turning impossible, EPS light flashing). Diagnostics were run and seemed to pass all, nothing more was done and the problem only appeared again over the past week with the power steering failing and the EPS light coming on.

When this happens on a motorway it's a very scary thing! The car is under warranty until end January 2015 so obviously I want to get everything done that's possible prior to that expiring (and the NCT will be due then too). Of course the dealer I bought this from is fobbing it off as not a big deal, but I can clearly see from wider reviews that this is a major problem in Merivas dating 2003-2008. In some cases I see that even when the steering column is replaced it doesn't solve the problem, but in any case I think better to do this anyway as a first step.

I will go to my garage about this on Monday but I need this to be taken seriously by them. The two things I have going against me here however is that A) I essentially know nothing about cars so can be easily hoodwinked by jargon and B) I'm a woman - so how could I possibly even understand? ;-)

Please help me out here would you - I've a baby due in about eight weeks and it won't be good if the power steering fails on the dash to the maternity ward!

Why is there a different engine noise when cold in my 2010 Volkswagen Passat DSG 1.4 TSI?

How much to fix Park Assist on a 2005 Volvo XC90?

Hi, I have a 2002 Volkswagen Polo Comfortline 1.2-litre. I bought it a few weeks ago and I have taken it for short journeys about two or three miles. It got its NCT five days before purchase, but I noticed the needle on the petrol gauge going down slowly, but on a two or three mile journey I didn't expect it to move at all? This is my first car so I'm panicking.

Thank you!

Hi, my mechanic has put a new (well second hand 2007) engine into my 2006 Ford Focus but it's misfiring on one of the cylinders. He tried replacing the coil, discovered that's not the issue and is now in the process of changing out various sensors, but nothing has worked so far. He says there's not a problem with the new engine and is running out of ideas. Would you have any suggestions?

When I turn on main beam the dipped lights still stay on, making a very bright patch close ahead that makes the main beam seem dim. What do you think?
