Now the head gasket appears to be OK (I hope....), it's time to move onto the next annoying little bug...
Our TD4 sometimes seems to loose power for a few seconds, before the turbo can be heard spooling up again, and normal service is resumed. For the last few weeks, this has sometimes been accompanied by the Mil lamp illuminating. Usually as power is re-applied at 50-70 mph. After a visit to a LR indy, and being relieved of £45, they have confirmed my suspicions, and diagnosed a boost pressure fault code. They couldn't ID the exact cause, and only suggested starting replacing the cheapest parts first, before possibly replacing the complete turbo unit...!
As the fault isn't always present, trying the soleniod test recommended above wouldn't reveal anything. Has anyone else experienced this? Do the soleniod's stick intermittently, or will it just fail completely? Ifv the vanes are a bit sticky, can they be cleaned using additive products, or is it a complete strip down job?
I intend (weather permitting), to get the ramps out next week, and try to lub and exercise the turbo linkages, clean the soleniod connector, check the vacuum hoses for leaks etc. But if anyone has any other ideas, they would be greatly appreciated..
Thanks.
