Hi there, hope you can help me...

I have a 2000 GTV 2.0. A few months ago it was slowly leaking brake fluid but not serious so I left it, topping up from time to time.

Last week the speedo stopped working and the ! warning light and ABS warning light came on. The brakes seemed fine so I carried on driving for a couple of days, the brakes started feeling spongy and unresponsive.

I took it to local independent who said that the gator needed replacing (I knew that), but that would probably not fix the problem as it also probably needed a new ABS system, but they woullnd't be able to diagnose until the gator was replaced. Problem is, a new ABS system would cost a lot more than the car is worth. If I fix the gator then it still needs the ABS replacing I've wasted my money.

I have been told by someone who claims to know what he's taking about that it's highly unlikely the ABS needs reaplacing, just the speed sensors. What do you reckon and how pricey is it?

By the way, I also have a 2001 156 2.0 which has just broken down with an inetrmittent cut out of electricity to fuel injector. The GTV is in mint condition, the 156 not so good, could the 156 be canibalised to repair the GTV?

Thanks a lot!!

I think that would be clutching at straws. The chances of all four wheel speed sensors failing at the same time would be very remote.

I've not verified this myself, but I was told a few months ago that it is possible to change just the electronics of the ABS unit. That may be worth looking into. I'd save a lot of labour.

What I don't understand is why the independent cannot hook up a diagnostics unit to read the error codes of the ABS unit without changing a 'gator'. What is that anyway? If that's referring to the brake master cylinder, then a leak there means the seals are gone. The gaiter is only there to keep foreign objects out of the master cylinder.

In respect of the 156. There is some commonality of components but you'd have to look at the part numbers on an individual basis to establish which are usable.

Cheers. Yes, needs the master cylinder replacing. The independent claims that they can't get a proper read on the diagnostics on the ABS due to the problem with the master cylinder.

I agree, seems unlikely that all the speed sensors aren't working. Just remembered that the ABS warning light generally didn't come on until I'd gone a couple of miles and it seemed to be dependent on tempearture as it would take longer to come on when it was really cold.

If you have any ideas / suggestions I'd be really grateful. Cheers!

Abs

Years gone by the speedo would get it's reading from a gear in the gearbox.Modern cars now get it from the ABS,so i would say the reason for your speedo not working is the ABS ecu is faulty and that is 1:your abs light has come on and 2: your not getting communication from the examiner.

Happened to my 156 and got it fixed by my local Alfa specialists.
