[928uk] ABS Relay

[Paul R Smith]

03 is the correct replacement, at £86.83 list price (you should be able 
to get 10% off for club membership at the OPC).

It's just a normal relay but with a Zener diode and heat sink added, 
presumably because the ABS solenoids generate lots of voltage spike when 
they operate. If you want to save money you can connect in a socket for 
a standard relay, leaving the existing relay containing the Zener diode. 
A second hand one would need to be significantly cheaper than the new 
one to be worth the risk that it will go soon.
