Hi again everyone!
I have been under the car to check everything this morning, and in a nutshell NOTHING!!
Rear bumper secure!
wheel arch liner totally secure! screws all in place captive nuts ok clipped in the right places
wheel bearing perfect
drum is sound no cracks or missing pieces including back plate!
As stated exhaust all brand new but no signs of damage, cracks, splits, peeling finish ,or damaged mountings
exhaust heat shields all in place and mounted properly!- back box, tapped to see if anything loose inside -there is not!.
plastic brake line covers all in place with correct mountings !-did vibrate a bit when tapped!, so fitted some improvised rubber dampers to stop any noise!
all Plastic trims at front of car including bumper checked all tight nothing loose that could vibrate!
headlights and drl,s checked to make sure no water could get inside them either !-plastic flaps and rubber bungs all in place no sign of water ingress!
Manifold studs checked for tightness including heat shield /cover
so ive checked everything i can think off unless you guys can think of anything i have missed?
next step is to wait till it rains heavy again then find some standing water and do the previously mention tests
IE- backing off throttle!, pulling handbrake, watching for abs light etc etc if nothing shows up I am just gonna stick with my steam theory until it either stops by itself !
or some thing fails Drastically!
to show me what it was all along!
Blinking P I T A though! might have to take up cycling!!!
Sorry had a funny turn there for a moment!!!
