Hi all,
I have a much loved Audi A4 2.0 tdi sline 140bhp 2007 (BRE engine code)
On my daily commute to work early morning my brake pedal went stiff and no brake force at
all so had to get my hands on the handbrake to bring it to a complete stop, fortunately i was
strolling along in traffic so it wasnt too bad, could not imagine if i was driving at normal speeds.
Pads where changed a week ago believe it or not but im assuming its the vacuum pump, so i will
get this sorted...
But the story doesnt finish there....
I then tried to limp at the bottom of the road as my work car park was 30sec away and then
The Engine oil pressure light popped up yes the big dreaded red one!
immediately the car was pulled over, switched off and AA was on route. He started the car up even
though he was advised of the situation and the engine ran rough and sound quite tinny.
So the car is sitting at the garage now, rocker cover has been taken off no oil wants to travel up
so the sump has been taken off. The oil pump is gear driven and has a hex balance shaft...
need any information and feedback in regards to what do i change, ideally the cost effective method
for me is just to change the oil pump..? But will that cure it..?The whole unit including the balance shaft
is very pricey but vag com diagnostic is not showing any further information apart from low oil pressure.
looking into this problem on this forum and others it is a common problem, but on the blb engine code which
is chain driven and has tensioners, so then from my information Audi upgraded these to the gear driven oil pumps
which is in mine, so what the hell has happened to mine? :-0
The car is always ran on the correct oil grade and it has never fell low, the car has always been warmed up
to the normal operating temp before driving over 2k and the millage in question is 112k
really frustrating as a major service was carried out including pads, water pump, timing belt and thermostat!
Now this, please comment any thoughts and advice will all be much appreciated
many thanks
