I know this has probably been posted a thousand times before....
When I bought my s320 CDI 2007 it had a slight hesitation intermittently.
the car has high mileage, 430km roughly 250k mile...
but has had quite a good history most of its life.
I knew i had issues with leaks etc, so i did all the usual necessary repairs.
Oil cooler seals in the v...
During the repair I carried out all the other related issue repairs, PCV, manifold flap motor and new rods, all gaskets and seals renewed, turbo tested, new core, and motor and flow tested, egr valve etc.
basically I didn't want to be going back in there again anytime soon...
After the repair everything went back together as it should, cleaned down and drove great.
But again intermittently there is a hesitation, doesnt have to be cold or hot, not necessarily from a standstill, can just happen as you drive and try accelerate, feels like its pulling back then lets go, i was sure it was a sticking egr valve of restricted fuel filter??? but it has me baffled, at the moment there are no dtcs stored and has done this on a few occasions now.
I know im not giving much to work with but just might be something silly that im missing?
Also changing through gears manually doesnt make a difference and there are no trans dtcs logged...
ECM sw is showing software status 05/06, would it be a case it needs or might take a SW upgrade??
Any help is much appreciated...
