Hi, I have an BMW X5 56 plate 3.0diesel. 41k miles. I have noticed that there appears to smoke coming from the exhaust upon acceleration. This is happening all of the time. Also, yesterday I lost power (as...
Have a go at the Positive Crankcase Valve (PCV). its located under the engine cover towards the rear of the engine in an odd shaped black plastic box alongside the fuel injectors, Dont pay BMW the Big dollars. Buy a filter for $50 AuD on Ebay or the whole unit for $120 AuD. You have to remove the engine covers to do it but thats not so hard really, just a bit involved and takes 10 mins to remove the engine cover. The actual filter is a throw away job, but the whole PCV assembly is just a degrease and clean. Its held in place by four small hex headed bolts, when you lift it you'll find the small can shaped filter pinned underneath. Swap the filter. its VERY unlikely to be your turbo at 41,000m.
The PCV is a known issue that causes smoking and even power loss, BMW actually did a retrofit kit PCV for use in cold climates., Are you in somewhere cold? and another possibility is not using the correct 'Winter diesel' in a cold spot. Very common fault for X5 owners going up to Thredbo or Perisher snowfields in Australia for the first time!
