What you get when you buy 55573953 QU
Most common cause of failure
In the Corsa D the ECU sits under the scuttle, so when the drains block, water floods it. The result is starting problems, injector control problems, rough running and misfiring (confirm the fault with a diagnosis before buying). Our refurbished housing is protected against water but not waterproof – so make sure water drains properly from the scuttle and does not flood the ECU.
