Engine Mechanical problem
2002 BMW 318 4 cyl Automatic 120102 miles
Hi im new to the forum and I was wondering if anyone can help me with my enquiry. Bascially I have a 4 door sedan 2002 318i E46 which I recently purchase 8 months ago. I started to notice that if I do not use my car for 1-2 days (i use public transport to work) and decide to use it on the weekend, when I start the car the engine shakes, the engine makes a rattling sound for a while and the idling (Rev meter) jumps up and down, at the same time I notice the smell of gas. THIS ONLY HAPPENS AT THE START OF THE DAY? After the inital start the car seems fine. I took it to the BMW dealer and they did not find anything wrong with the car.
They said I was due for a service (even though I still had 3000Kms to my next service)my current reading is 120,102kms. I got the full service which they said it was best to do. And still the same thing happend - once again at the start of the day. I went back and they did a diagonstic test which came back fine.
I was the told to change my petrol from premium to normal unleaded because the 98 oct petrol I was using was to high, still no change.
im not sure why my car has these problems. The common signs are
if I dont use the car frequently the following things happen when I start the engine for the first time
1. Engine shakes
2. Rattling sound - sometime a popping sound
3. The idiling (Rev meter) jumps to 2rpm the drops below 1rpm and increases again - this lasts for 1 min
4. I can start to smell gas
For example.I start my car in the morning it has the problem I drive to the shops its starts fine. I have told this to the dealers and the services tech and even requested that they keep my car overnight so they can hear and see the problem but they kept saying theres nothing wrong, if there was some symbol will flash up on the dash board.
if anyone has every experienced these things, I would like to hear from you and how you resolved this issue. I can never get a soild answer from the dealer or service department.
