JA: What is the model of your '03 Mercedes?
Customer: A class A140

Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

So there is a whine comming from the pump ? and its full of fluid?

Customer: replied 2 months ago.
Hi, not sure where the noise is coming from exactly, but the noise is not always present. Yes it's full of fluid

Sounds like you have a steering pump going out, you can take the lines off at the rack and connect them together to see if it is a pump or rack, sometimes the rack will have a internal failure and cause a blockage making you think the pump is bad

Thanks Shawn. So if it is the pump then I should just replace. It's nothing to do with bad/wet electrics? (since washing the car as mentioned) About 6 months ago the car suddenly went into limp mode and the power steering went then too, I replaced the brake light switch and calibrated the power steering (left lock, right lock) and it has worked fine until this issue, just wondering if it's related. The rack sounds like it's a much bigger problem (if it is that)
