2.0L audi no oil pressure

[jamesdb]

Hi Guys
Just got this car in,2005 audi a4 2.0tdi ,Customer was driving down motorway when red warning light oil pressure low came on,he stopped,checked it for oil and put in half a liter and drove it a further 20 miles with the oil light on as,also the brake pedal went solid so he lost the servo
first inspection-when started no big rattles or noise so changed oil and filter and fitted oil pressure gauge and started,no oil pressure,
Removed the sump and the chain tensioner,chain sprockets all look ok
anyone any ideas on what could be the problem,would the oil pump itself be gone weak???or something else???

Ok Thx!

Ok thx, will check it later, does the t-belt and pullies,etc have to be removed to take out this shaft?
Any special tools needed?or timing marks I should look out for

When I turned the crankshaft the little shaft in the oil pump was not turning, I assume this is my problem before I strip it all down and I can price all the parts up for the customer.....

took the shaft out and one end is nearly round,can this be replaced on its own or do i replace balance shaft and change from chain system to sprocket system

An update guys
Fitted the new shaft, started ok and oil pressure straight away, turbo was noisey so got a second hand turbo and fitted it, car seems ok now but for how long I don't know.......
