Your first course should be to read the fine print of the warranty agreement you'll have been provided with (not just the leaflet) and this will give you a long list of items excluded and also exclusion of fair wear and tear. See if it specifically mentions or excludes the injectors and injector coils. Forget the spark plugs they'll be a wear and tear item so excluded. The injectors also wear out over time so the warranty company will probably say they haven't actually failed they are wearing out and aren't covered. If your BMW specialist can prove they have completely failed then you stand a chance of some recompense but don't hold your breath.

I think you stand an ever so slightly better chance of throwing it all back at Car Giant if what you say is true and relate to them how you've been missold the warranty. Write down everything you remember about how you were sold it, what was said and who said it. Put this to them in writing to a director by recorded delivery and they without accepting any of your points nevertheless do something for you. Again no holding of the breath.

Other option is that Car Giant have a responsibility under the Sale of Goods Act to make good any fault with the car in the first 6 months so you could check out with the Citizens Advice Bureau exactly what your consumer rights are. You could then approach Car Giant with a view to taking the car back and refunding your money less any reasonable charges such as depreciation. Very difficult and very time consuming to achieve at any time after purchase let alone 6 months but it is an option. Or another similar car to replace your faulty one then they repair yours at their cost.

Warranty companies make profits by paying out as little as they can and have offices full of experts at doing this and fobbing you off. You'd be better off cancelling it, getting as much of your mone back as possible (not easy I acknowledge) and then putting the money you would have spent on warranty aside for situations like this.

If you searched these forums you'll find a lot of people with almost identical stories like yours, "fair wear and tear" popping up everywhere and a paucity of people delighted with the way their warranty claim was handled.

Hi

Does your car have a full and up to date BMW service history? Reason I ask, is that I have the same car as you which coincidentally I bought from Car Giant when it was 2 years old. After a few months it started to jerk under gentle acceleration and eventually a yellow engine warning light came on.

I took it to BMW and they diagnosed a faulty injector which they replaced under warranty. Every 3 - 4 weeks after that the same happened with the other cylinders until all 4 were replaced.

Last year, the same happened - jerky acceleration but no warning light - except now I was out of the warranty period with BMW and relying on my AA Warranty I bought from Car Giant.

I did a bit of Googling and found out the BMW are having problems with coil packs fitted to 2.0i 4 cylinder engines on 1 & 3 series cars made around 2007 & 2008 and they were replacing them free of charge. I rang the dealer and asked if my car was covered and it was. Booked it in within 2 days and the job took an hour. Car is back to normal.

For info I have a 320i SE 170ps E92 Coupe with a build date of Dec 2007.

If BMW won't help you then I suggest going into Car Giant and talking to them directly. I have read their aftersales is normally pretty good.
