Default The engine light is on in my Swift and the guys at the garage can't resolve it

Hi my name is Colin, thanks in advance for any advice.

I just bought a 2013 Suzuki Swift 1.3 Diesel from my mum but the engine light is on and it has been for several months. Call me dumb, but I've been led to believe it's not a major issue, despite not knowing what that issue may be. There are some odd things going on though.

The "symptoms":

- Sometimes the car loses power after stopping. For example, if I stop at a red light and then try to pull away again, there's nothing coming from the accelerator. It's only happened once for me in the week that I've had the car and it regained power after a few seconds but my mum said she's had to turn the car off at the ignition and then back on again to resolve it. She says she can predict when it's likely to happen as she will hear what sounds like a loud fan running in the engine, that she can't normally hear.
- When stationary with the engine on, sometimes the car will rev up and down repeatedly from around 750rpm to about 1200rpm. It appears to be random and it doesn't matter if the car is in gear or in neutral, whether A/C is turned on etc.
- Sometimes after turning the engine off at the ignition, a fairly loud "humming" noise is heard from the engine that fades out over about a 5-10 second period.

Any ideas?

I think it's important to point out that my mum is a driving instructor. Being a diesel engine, the particulate filter is suspected as being the possible culprit here due to the way the car has been driven.. at least that is what the local garage thinks. Even though the particulate filter warning light has never been on, the garage has attached a computer of some sort to the car and the error code has indicated that it's something to do with the particulate filter. I have no idea whether this is just a maybe or a definitely. I've done the recommended "fix" to clear the filter to no avail so now I'm stumped. (50mph+ and/or +2000rpm for 15mins+ to clear the filter. I drove 200miles and then back again a few days ago and tried out variations of that method thoroughly).
The car has also been to the Suzuki garage but they simply said that the glow plugs seem to be the issue.

Thanks for any help and sorry for the long post!

First up, buy a code reader/scanner so you can find out what is causing the engine light to be on, or ask the mechanic what the codes are?
