BXClub Wakefield I've heard is quite good with these, usually open at weekends, with parts on shelf.
Warning, dont let him tell you the cars not worth repairing as I've heard he looking for one of these. :lol:

Its probably a wheel sensor - and its probably the screen of the co-ax cable which has corroded.

To keep it simple to start with disconnect each sensor in turn (fronts have plugs near the bulkhead, backs under the back seat, and measure the resistance between the centre pin and earth. You may find one is open circuited - in which case you have found the culprit.

I soldered a length of co-ax into mine and insulated it carefully. Still working on the back nearly 6 years later!

I'll confirm what Jeremy has said here. Use a good quality coax, heatshrink, (Glue lined) and patience. With sensors costing the thick end of £100, it is well worth repairing them. You should measure the resistance as being between 800 and 1100 Ohms on a good sensor and If your sensor is open circuit, then it is best to cut the cable around three inches from the sensor body and measure again. Open circuit now probably means you'll need a new one. Don't discard the plug at the other end, You'll need it. Take a close look at it. You'll be surprised who makes it! Good luck.

If you check BX diy on the club home page there is an excellent guide on how to check this out.

If you come across any problems or need a sensor let me know, there'll be one round here somewhere. :)

Excellent Gareth

That gives me just enough time to check my front sensors
Before putting in a bid

Will anyone else be bidding on these?

it would silly to get into a bidding war if i only need one :)

Nice if you can get it cheap enough, but as these are now funny money (90 + vat retail) I wouldn't think it will be too cheap.

Luckily I have a spare one here if you need it. :D

ABS

Post by Mike E (uk) » Sun Dec 11, 2005 11:12 pm

I had the usual flickering ABS light problem.

All the sensors checked out OK.

Cleaning the connector to the modulator block cured it.

Nice and easy, cost only a squirt of brake cleaner solvent.

:D
