Thanks for the inform. For my car power still have, only sometime if stop and wait for traffic light will engine die. The rpm little up and down and is lower then normal..the petrol and air not smooth...
And yes I wish to find one workshop that can try with spare parts before replace it. Will go down Codewerx soon once I have the free time. These few days busy working...
Yep, happened to me before (E60 2008). Usually start of day no problem, only after driving for some time on highway, exiting and reaching the next traffic light, it happens.
You try this: At traffic light stop, try switching to Neutral. If the RPM still up and down, then Codewerx or any of the site sponsors should be able to sniff it out.
If RPM stops the up and down at Neutral, it could be the transmission
Free time is how we can manage it. A friend once advised me when I was withholding repairs: We pay so much for a premium ride, we have to ensure that it is maintained and serviced right so that we can enjoy the peak performance of the car every minute of it. The earlier we get it fixed, the more we get out of it. Otherwise why do we fork out so much in the first place.
You can try make appointment early in the morning. Ask your office for 1-2 hours time off. Drop the car at the WS first thing in the morning, explain the problem, leave the car there and catch Uber to work. They will update you regularly and advise you when to pick up if done. No worries at all (only worry later when paying...lol) No need to take a day off and sit/stand there to watch. Our site sponsors can be trusted to do a good job!
