Hi all , first post , so I started my ownership last February, had been looking for ages , lock down didn’t help ,
Came across this car on Facebook and went for it
2003 520 m sport , 96000 miles
I love the car , not with out it’s issues ,
So far I’ve done new rotors and pads all round , 4 new tyres, full service wipers front window seal new coils and plugs ,
Wheels need Refurb and I’d like to refresh the suspension front and back ,
So here is a few questions
Car lately is running a bit ruff and stalling at times , have a engine light on , not sure where to start
What are people doing to source parts ? Bit of a mine field out there , local motor factors are a bit hit and miss,
