ok cheers, you really are being quite helpful to this n00b.
according to that site, the part no. i need is: 34521164458
http://bmwfans.info/parts-catalog/E46-Coupe/Europe/318Ci-N46/R-N/jan2005/browse/brakes/brake_master_cylinder_dsc/#1164458_2
is that right ? and I need two of the basterds?
Its No.2 in that diagram, just check the underside of the master cylinder, if your car is a late model it will have two of those sensors. Both are the same part number.
Its not a huge job just a bit fiddly.
Ok here's a weird thing.
yesterday before setting out on a longish journey I checked all my tyre pressures as I had a slow puncture in the rear driver's side.
I left the engine running whilst inflating each tyre to the correct 34psi
when I started the task, the yellow DSC and brake fluid level lights were on.
when I had finished all tyres, I got back in the driver's seat only to notice that the light had gone out.
I drove for 100KM (maybe a little less) and the lights came back on. They stayed on.
Later that day I went to my local tyre place as one of my tyres needed replacing for the NCT, while I was there I got him to fix the slow puncture in the other one.
The lights were still on at this stage.
after fixing both tyres, i drove to the nearest petrol station to chck pressures.
they were bit off after yer man was at them , so in put back in the correct 34psi
when i got back in the driver's seat again, i had noticed the lights were out.
coincidence ? ?????????
they've stayed out so far but I have only done about half the distance I did yesterday when they came on
Odd, does anyone know if the E46 has tyre pressure monitoring available as an option? Could this be it?
yes my one has a TPM button and the TPM light goes off when the tyre pressure gets low.Quote:

This was a pain when I first got the car as I didn't know that one tyre had a slow puncture and the TPM light came on and i didn't know how to reset it.
Had this kind of problem 3 years ago. DSC lights lighting up like Christmas tree every 30 mins.Had it scanned and it was the dsc pressure sensor. It was replaced and codes were cleared. Bought 2 sensors and was told that only one was needed.
mine's a bit more random then every 30 mins, and the brake fluid light always comes on with it.Quote:

can get them from china for around $45USD, so i might as well try that first
You might as well buy 4 of them Chinese ones, you'll be replacing them that many times compared to a genuine one!Quote:

cheers, yeah I feel that may be the case,Quote:

but yeah, it says brake pressure sensors
