HI folks,
we thought :where better to come for help with a strange wee problem than the forum of other T4 owners and fans! Any help or advice is greatly appreciated.
Our T4 TDI has twice had a mysterious loss of power.
First time was six months ago, travelling along in third gear, ( windy country road, nto heavy load) suddenly no power, and high revs. We stopped, and after waiting for the AA the van started again no problem and the fault didn't reoccure. Since been serviced and running fine. then yesterday, it did it again, in second gear, low revs, power just cut out, no repsonse on acclerator, but engine reving hard. Once agian after shutting ti off and resting for a while it was fine! The only thing I can think of in common was both days were wet!
WE are now wondering if this is a serious problem- is it symptomatic of a major thing like the cam belt needing doing ( ours last done at 78,000, we are now at 120,00 and planning to get it done soon).
Thanks for any ideas you might have!
Cheers Emma
