So, it's been sorted now it had a failure on the ignition coil on cylinder 1. They found that there were a smaller amount of misfires from another two coils. All the coils have been replaced and new set of spark plugs. Thanks for the advice!

Sadly I am yet to get a diagram to locate what I am looking for. If anyone has advice on where to obtain engine diagrams I would most appreciative. So until then i think I'm stuck.

I have no experience with cars. But I am a lab tech so changing a sensor shouldn't be too far removed from what I can do. It seems a cheap and relatively easy job if I prepare properly. I think I will try this myself before getting further assistance.

Update: next door had one a diagnostic thing and I'm getting the error codes P0115 P130A.

Fair point. I have done a bit more reading and are far less worried than I was previously. It's a 1.8tsfi so petrol. And I love it. So there is a tinge of complete dread in all of this. But yeah I will let you know what happens.

Thanks. Yeah I'm gonna get someone else out to have a look. It was a new garage as I just moved and the car has never had a fault in the last 7 years so I'm just a bit suspicious.

Hey, Just had a service and MOT done on my car. They did highlight they suspected the head gasket might need replacing as there was some oil in the spark plug well but it wasn't urgent. I managed to get it home but the next evening it's showing engine light and EPC warnings on the dash. It's sputtling on idle and there is an electric alarm doing off in the engine bay which from what I have read could be the turbo? Anyway should I be worried and what would you look at first? I'm assuming it's a misfire from what I have read. I am gonna check the spark plugs for oil and possibly the air filter incase it's somehow installed incorrectly. But any advice would be appreciated.
