Re: Renault Laguna I - Phase 2 - Electronics - ABS Warning Light

I had ABS light showing on my wifes 02 1.8. After MANY garages saying it was the drivers side rear sensor faulty and changing it (even though Id told them other garages said the same) fault still showed. Eventually got recommended to a local auto elec (not Renault specialist) & he diagnosed corroded pins on ABS ECU . The ECU is in front of the passenger side front wheel, so probably got wet at some time. Changed the ECU (50 from scrap yard), re-programmed to car & all OK. a few month on & fault re-appears. This time it needed another ECU & rear passenger side sensor. For now its sorted....
