Hello and welcome to Just Answer, my name is \*\*\*\*\* \*\*\*\*\* I'm here to help answer your question today.

Ok great
Automotive Expert
How high does the RPM go ? Also is this a new problem, how long has this been happening ?

1000 I bought the car two weeks ago
Automotive Expert
Ok, if the RPM goes up to 1000 when you first start the car and then goes down to normal, about ( 600 ish ) then it sounds like everything is operating correctly. Do you have any warning light on the dash that are illuminated ?

Only the light bulb failure
Automotive Expert
The one for a burnt out bulb. Ok sounds like it's working correctly then. Is there any other concerns ?

it rattles a little bit
Automotive Expert
Does the rattle noise sound like it's coming from the engine area ? Does it rattle all the time or only when you first start the engine ?

Not the engine but the
Automotive Expert
What area of the car does the rattling noise sound like it's coming from ?

Not sure
Automotive Expert
Does it only make the noise when you're driving ? Or does it make it even when the car is sitting idling ?

Sitting idling
Automotive Expert
It could just be some panel that vibrating and making noise. Or it could be one of the heat shields on the exhaust system rattling. You may need to take it to a local mechanic shop and ask if someone will go for a quick drive with you to have a listen to the noise. They could probably get a good idea what the problem is once they have a listen to it.

Hello good morning
Automotive Expert
Hello, good morning how are you doing ?

I'm doing ok you think of my throttle plate is dirt could result to the issues w the car cause no check engine light ain't on
Automotive Expert
It wouldn't hurt anything to clean it but I don't think it would be the problem. VW's don't really have too many issues with the throttle body getting dirty and causing problems.

What's usually the most common problemsCause when I step on the gas it's like something is stuckOr plugged or cloggedSomebody said some kind of valve is dirty
Automotive Expert
Like it has no power and the acceleration will cut out ?

Like it don't want to go but it goesCause when I cleaned the throttle plate it kinda got a little worse
Automotive Expert
It could be that the throttle body is faulty. Inside the electronic portion of the throttle body. I have seen them fail before but you would have a Check Engine light on. Or possibly you could take it a shop and ask them to perform a Throttle Adaptation on the car. This commands the computer to activate the throttle body so it can learn when open and closed throttle position is. It basically calibrate the throttle.

How much does that costAt what kind of shop or could it be the throttle position sensor
Automotive Expert
The cost probably won't be too much, maybe $100 and I would take it to a shop that specializes in European vehicles. The throttle position sensor is internally all part of the throttle body

Ok thanks for your help it's very much appreciated
Automotive Expert
No problem hope you have a great day

You too
