Ok, so I finally did it. Thre is what they did:<p>1. Engine oil - changed;<br>2. Oil filter - replaced;<br>3. All controls and systems - checked.<p>Extra things:<br>1. Squeak in right passanger door - fixed, they knew the problem;<br>2. Air Flow Meter - replaced under warranty. Car is running like "new". I have a feeling of extra HP as the meter now works fine. So called MPG is lower too!<p>Costs:<br>290 Euro (grrr).<p>No other problems.
