Hi all,

Diagnostics on my Bravo have turned up the ABS pump as being suspect - I have checked around on the net and it seems the HLX Bravo uses the Teves MK20 system, which is notorious for having bad solder joints on the electrical side (there's even a company specialises in refurbing these units as they are primarily used on Volvos) - does anyone know how to remove this unit, preferably keeping the pipes intact so I can remove just the circuit board and hopefully effect a repair? It would save me a hell of a lot of hassle if I could do this.....

Cheers

Well, despite first thoughts it would appear the answer is "yes" - you can remove the module without removing the pipes! You need to remove the battery, battery tray, air inlet pipework, and fusebox in the corner - then you need to remove the two bolts holding the ABS unit onto the bracket and there is just enough play in the rigid pipes to move it clear of the bracket and lean it slightly forward so you can get to the 4 bolts on the rear of the ECU. These are Torx E-5 bolts, but can be easily removed with a 4mm socket - you will need a small 1/4" drive ratchet to squeeze in though, as space is at a bit of a premium. Once removed, you need to hacksaw the edges of the unit to gain access to the circuit board within, then you need to re-solder a few connections. Basically the Volvo guide at this link tells you how to effect a repair once you have the module off, as they use the same Teves MK20 system:

The result? Soldered it up, put it back together last night and left the silicone to cure, fitted this morning and I no longer have a permanent ABS light - lovely
