Title: 2.2DTI
Post by: EMD on 25 January 2016, 14:43:07
Looking at a 2.2dti estate so having never owned one and spotted a possible buy what do i need to look out for engine wise . Should it pull pretty strong , and anything to test while im there looking around it  :-\ Its done 150k but looks clean and presentable with just a few minor body scuffs  :-\

Generally very reliable, until the fuel pump goes at which point they tend to be written off.

Ive known about the fuel pump issue a while but what is the cost of repair or replacement , seem to recall Mr DTM saying they can be repaired  :-\
I think the biggest issue is running the fuel down low and running the car with the fuel light on
for long periods so that the pump overheats  :-\

The pump is attached to the engine and uses diesel to cool itself - it won't overheat unless you run it dry, though, it's not like an in-tank lift pump that might run hot when not submerged ;)

So it's more commonly killed by drain-back and not priming after a filter change.

Ah i see  ;) Was there someone on here that mentioned adding a little 2 stoke oil to the tank every now and then  :-\ Wonder if the pump is only a 1 off for the omega or is available from different cars  :-\

All well documented... believe it's a VM44 used on allsorts of cars/makes... but it doesn't get any cheaper elsewhere and I believe the pumps are coded to whatever application they're fitted to, so not a simple case of swapping the pump from a Vectra C for example :-\

New pumps start at around £1500 plus labour if that helps your decision any ::)

Now you understand why an older diesel(ANY old diesel) is so cheap. And why it is such a bad buy.

Fair do's  :y Although ive been told the car has been faultless for over a couple of years it does play on your mind if/when eventually the pump will give up .. shame  :(

The pump isn't the only £1000 bill on a used diesel either!
The key to owning one is buy it new, halve the manufacturer's oil-change interval, and sell it before it reaches 100,000 miles.

If you buy them new, and service them correctly, I think they are good for more than 100,000 miles. But you are buying second/third/tenth hand, so you have probably no knowledge of how it was looked after in it's early years.

Added to which, hardly anyone on here wants to work on them so unless you do your own repairs beware!

I believe that people in the know, on this forum, recommend an oil service every 3-4000 miles. Sod that.

2 things happen to the VP44 pump fitted to DTIs in the UK:

1) It wears mechanically, catastrophically, if run dry, as the diesel is the lubricant. Not repairable.
2) The electronics pack up, seemingly if run dry, due to lack of cooling (by fuel). About £300 plus labour repair.


Beyond the pump, the intake gums up and needs cleaning, along with EGR, due to amount of EGR that the engine runs.

With  an efficient petrol engine that's an extravagance. But with a modern turbo-diesel it is critical for improving long term durability. Really cheap too, compared to the cost of a new turbo.

Yep. I meant diesel. Petrol is five years or 30,000 miles.  ;D
