Been busy this past few weeks with so much happening that i didn't have the time to update this thread. Below are what have been done to the car
8th Nov
Car broke down again which i suspect is down to the crank sensor as the car would start when cold but didn't when the engine is hot.
The next morning send it over to Autobahn Sunway to have the parts replaced which is fuel filter, crank sensor and change all the pulleys and belts
Old fuel filter dated 07
Installed new
Sorry couldn't take anymore pics cos was busy chatting with another OM while the work was carried out lol.
Now with the new crank sensor installed along with the filter and pulleys again she drives beautifully on the highways but during low speed or idling the problem came up again which really stumped me ... The engine would just dies off even though i change the crank sensor lol Upon starting again the car had rough idling very lumpy but when on mid to high rpm she's purrrs nicely. Went to optimum and have it read the codes via Autologic it came up with a Vanos exhaust side error. Anyway i went back home thinking that it could be the coils that causing the lumpy idle.
Since my new ignition coils arrive few days ago i decided to DIY again :4:
New coils
Taking off the valve cover which was very easy and revealing the old one
Comparison between new and old
20 mins later all changed :4: Thanks to e34_lover for lending me his ratchet :top:
Unfortunately upon starting up the idling was still lumpy ... Come monday morning i decided not to take chance and have it towed to Tedco Motorsport for further inspection and rectificatiion - 12th Nov
It was diagnosed as having a stuck vanos on the exhaust side ... hence the we have to open up the top part of the engine which to my joy still looks clean and pristine for a 16 year old engine :rock:
Close up ... Sorry for the crappy pics
When we took out the Vanos and take off the cover plate we were shock to see this
In the pic the vanos at the top is what you would normally see and mine is at the bottom. Apparently it's filled with some sort of silicone and further checking with other mat salleh forums it seems to be a factory solution from BMW to stop the solenoids from moving ...
22nd Nov - Anyways after more than a week of deliberating (actually reuben was busy doing something else :slug
we decided to install back the Vanos and see how it goes. What do you know ... It works like a charm !!!
Reuben decided to take off the Unichip as well to see how the car responds within this few weeks. The car now idling very smoothly and drives great :rock: However reuben did point out that the clutch is getting thin and needs replacement plus need to check on the ICV and change the throttle position sensor (TPS)
To be continued ....
