Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
I would advise you to ring Autobahn asap.
Your engine is a little more susceptible to electronic faults from water.
It may not happen for them when they washed the engine, but it can happen a short time later.
They should cover whatever may be wrong, because they should know that by now.
Can you let me know your outcome?
I hope my advice has been of assistance to you.
Do you need any further help?
I hope you have had your car fixed.
