been getting the dreaded code 0638 for several months , always reset with OBD and sometimes it would stay away for weeks ,, the van seemed to run fine, plenty power and smooth . average fuel consumption 27 mpg ,
However after my recent horrible trip in France ,, the code stayed on and would not reset ,,the van went limp a few times .
So bought a new Throttle control actuator from Coastal Motorhomes , it was the upgraded Marelli part with the new loom attached and adaptor for connector and gaskets .
getting the old one off was a bit of a pain as the bolts tend to rust into the engine , well documented in my recent threads about my terrible holiday , ended up having to drill 2 broken bolts out ,, However once that was done installation was a breeze .
also checked MAP and EGR are clean and sprayed top of engine around head bolts , injectors etc with loads of WD
Recent test drives of 20 -30 miles in all conditions show fault completely removed , van actually drives even smoother , accelerates quicker , revs faster and fuel consumption reduced now averaging 29mpg thats 2 mpg better .
Total cost for just the parts £234 , but if a garage does it add £400-700 ????? for labour VAT etc .
next job is change oil and filters
