I have a Seat Leon mk1 2001, 1.6SR engine.
I got two problems, I don't know if they're connected or not.
Firstly, it consumes oil, around 1 - 1.1 litre per 1000 kilometers. I guess that is around 0.22-0.24 gallon per 621 miles..?
I've tried to check if there's any drops of oil under the car but I haven't seen any.
Where should I start to check this?
Secondly, it loses power while driving and the rpm goes up and down while idling when it's warm. The loss of power is most noticable when driving over 100 km/h and especially uphill. But even when driving slower it has started to occur.
I got an error code:
00537 - Lambda (Oxygen Sensor) Regulation: Upper Limit
I've gotten the Lambda/oxygen sensor replaced and checked for error codes and it was still there. I removed the error code, checked again and it was gone. Then I went for a test drive but the problems were still there. The change didn't make it any better, now after a few days it even seems worse. It happens more often while driving slowly. It stutters and lose power. Almost like it's going to stop. The error code came back after the first test drive.
What can it be? Where should I start to troubleshoot this?
I'm not experienced with mechanics, I can do some things myself if I have the tools and it can be done outside without going under the car.
What does Upper Limit mean in the error code?
I have checked the air filter and it was dusty and I guess I should change it anyway. But it wasn't extremely dirty. I looked at the MAF sensor at the same time and it looked clean, not any dirt at all.
Help would be much appreciated! Love this car and really want to get it to work well.
