Hello to All! Need help too!
I have a Series 530d Touring - a beauty and awesome to drive!
...but lately I have noticed a power issue. When the engine is started from cold she runs well and the power is normal - intense and fast. But after running on the auto-route for awhile and when the car is warm - it loses acceleration power. No guts at all.
But if I pull over and stop the engine and then re-start and rev the engine once or twice then pull away the power comes back again - but only to lose it again after awhile.
Your insight would really be appreciated - Thanks!
