Hill Start Assist Malfunction

Hi All (and Happy New Year to you),

Long time browser, but first time poster here - thanks to having owned a very reliable B-Max (1.6 diesel) until now...

I have an issue with my Hill Assist. It was coming on independently, mostly when starting and pulling away but a couple of times whilst driving at speed on dual carriageways (lots of smoke, heat and panicking!).

After several diagnostics (which reposted nothing), new brake callipers and checks from my local Ford Dealer, my local mechanic suggested switching off the hill assist and it's completely fixed. No issues since and at least 4000 miles covered since in did.

So - my question is this. Does switching it off have any impact on any other aspect of the car's performance? I've been told the issue was caused by a faulty ABS pump and that would cost upwards of 500 to replace. Does anyone have any experience of this issue or any advice?

Thanks

I drive a ford Transit at work and yesterday i had a similar issue.
The van ran fine until i went to restart after making a call. The ABS, Traction control and main braking warning all lit up like a christmas tree. I also had a message on the dash about "hill start assist unavailable" and "Major brake malfunction,STOP safely". Thee AA came out and diagnosed a faulty wheel sensor for the ABS system.
Maybe you should get the sensors checked ?
I had no excess smoke issue though as i refused to move the van until checked by the AA.

1 litre Zetec Turbo petrol 74Kw / 100 Ps. as in my avatar.
