AlfaKay 0 Report post Posted May 13, 2016 Hi, I've recently changed the 50A pump relay on my 2005 147 2.0 TS (109,000km) after the "Selespeed System Failure" warning came up. It worked fine for a short while then it failed again. Relay has gone bad! Does anyone have a clear idea why? What's the fix? No apparent leaks. PS: I bought the car recently and it was about to be junked. Previous owner must have tried to fix it too. I love Alfa's so I'm welling to fix it, if cost is reasonable. Thank you.

Whilst sitting stationary, engine off, with the key in MAR & foot on the brake see how many gear changes you can get before you hear the whine of the pump. 2-3 changes is the norm, if the pump runs every change, time for a new Accumulator.

Thank you Turismo. Cheer. Edited May 20, 2016 by AlfaKay Quote Share this post Link to post Share on other sites
