I have an Audi TT 51 plate with 90,000 miles which is highly modified. Yesterday I lazily took my car through a car wash. After coming out I noticed there was steam/smoke coming from the engine. I drove down the road and it continued so I pulled over. My engine heat was showing 130 degrees. I waited to let the car cool down for half an hour and then drove home with no further problems. I have now been out in my car today and was enjoying a country road for no more than 10 minutes when my engine began to lag at 3000rpm and seemingly didn't accelerate after that point. I again let the engine cool down as it was showing 130 degrees. When I then drove home it seemed like it was pulling again and seemed normal. Should I be concerned? Any idea what the problem might be and how to fix it?

Thanks
