Yesterday my car ( diesel ) was really difficult to start but after several turns of the engine it eventually coughed and spluttered into life but with a constant misfire and as I was 50 miles away from home I didnâ€™t fancy risking it home so called on the breakdown recovery cover I have with my insurance company.
Out comes the mechanic ( who later told me he had been a mechanic since leaving school ) and although he was a nice guy we initially almost fell out. Before he knew what engine I had in the car he saw the 75 and said its probably HGF (Head Gasket Failure) failure. When I told him that was unlikely as it was a diesel he said that doesnâ€™t matter I have seen loads of these with HGF , really !
When he heard the car he then suspected EGR (Exhaust Gas Recirculation Valve) valve but on inspection it was clean ( as I had cleaned it last year I didnâ€™t expect that to be the problem either )
So then onto the next diagnosis which was your turbo has gone !
Anyway I got the recovery home I wanted which was all I have the break down cover for, and certainly not for the expertise that comes with the truck !
So today i decided to take a look with fuel pump, PCV (Positive Crankcase Ventilation Valve) filter MAF (Mass Air Flow Sensor), and injectors in mind
My car only has the in tank pump being a a later model facelift, and I turned on the ignition and could clearly hear the pump working for the required 20 seconds or so by listening at the fuel filler neck with cap removed.
Along comes Steve ( Devilish ) to lend a hand, listens to the engine spluttering and said straightaway that it sounded like an injector problem . We did check the MAF first by swopping his with mine but no different so next step was to try some STP injector cleaner which he had bought with him, so off to the garage with a misfire, poured in the cleaner and put in some more diesel to get the fuel up to the right mixture with the cleaner and set off home.
Within a few hundred yards car back to normal and problem solved.
Cost of cleaner around Â£6. I donâ€™t get my diesel from one garage in particular so could have had some inferior stuff in there at some point, so lesson to me to use fuel treatment more in future to keep the injectors clean
Imagine what a garage could have charged for a Â£6 fix !
A big big thanks to Steve

Planning is an unnatural process, much better to just get on with things, that way failure comes as a complete surprise instead of being preceeded by a period of worry and doubt
