Two years ago I bought a Suzuki Swift Ddis from an authorised dealer. The car was running fine until, a few months ago, the turbo failed. The car was still under warranty, but I had to pay £100 to recover the car. After it was inspected, the dealer informed me the engine was damaged and it would need replacing, which they did under the warranty.

However, within days of getting it back, the car started making a cracking noise and I was forced to return it. Again, the dealer told me it was the turbo and again they fixed it.

Now the engine has started leaking oil and showing the same symptoms again. Only this time the warranty has expired and I don’t know what to do. Either the dealer hasn’t done their job properly or this is a common fault. Can you help?
