Did my first job on my new car. More for safety than anything. The headlights were horribly foggy so set about them with sandpaper and polisher. Came out great.
Then investigated why the maf was held up by a sponge, someone had taken out the mounting bolt in the bracket so it just rattled on top of the engine, so obviously a sponge was the correct 'fix'. Now fixed properly.
And the final one for today was to reach down into the engines guts to reattach the end of the webasto heater exhaust to the pipe that goes out the bottom. This would explain why exhaust fumes were ending up in the cabin as it the exhaust was just hanging around the engine bay and getting drawn in. Hopefully not any more!
