I bought an n53 engined e60 525i and have been used to a bit of a rough idle from cold for the past few months. No codes were being thrown up.

A normal CEL has just appeared and a half filled CEL is now flashing beneath it in the bigger diaplay and the car did not want to start but has just soldiered home on reduced power, about 5 miles.

Reading around suggests anything from coils to injectors and HPFP. Unfortunately I don't have too much time to hunt this down, so can anyone recommend a specialist near North East London that preferably won't pull my pants down!?

Thanks

I attempted to find a specialist when I was having issues with my n53. Didn't find one in the end but it turned out my local knew a bit about them and switched around some coils as it's been ok since. It could be coils, knackered injectors, spark plugs or a combo of all 3. I recall that the NOX sensor can also cause problems.

I spoke with a place called Gilbert's who seemed to know a fair bit about them, they are over in west London though.

You might like to try Brunswick Garage in Arnos Grove. They are quite good there, and very honest with their pricing. Plenty of expertise as well and a good approach to fault-finding beyond pluging in a computer and reading codes.

Not used them personally (as the problem was solved with new coil packs) but when I had a similar issue Highams Park Motor Company was recommended to me as the place to sort it.
