Now going to have to bite the bullet and take it to a garage - this has got to be the only car I've never been able to change the oil on myself.
I might just get the garage to loosen it a bit and then I'll do it myself.
Any advice on how I can avoid it becoming so tight in future - or how to undo it myself ?
Are you using a standard 8mm allen key? A decent motor factors will probably sell you a better quality one which is a lot longer to get more leverege.
Failing that, a piece of pipework (eg 10mm dia) wedged over the end to give more torque.
Failing that, a tap the Allen key with with a hammer.
I know its obvious but you are undoing it the right way? I am left handed so always get confused especially when lying on my back under the car! Much to my Dad's annoyance when I was a young fella and he used to supervise these things!
Btw the Allen key sump plugs are much better than the alternative ones sometimes fitted to the 147 with Torq fittings, they were a real pig.
Avoiding this problem..do it up yourself but not too tight, it only needs nipping up really. Don't forget a new copper washer on the sump plug. The sump thread can easily strip if it is too tight.
Garages (especially those employing YTS or kwik fit etc) will always tend to do bolts too tight, especially sump plugs and wheel nuts.
Same with the filter..nip it hand tight only.
