Hey guys as title says I have one of these with the chocolate gearbox and plastic manifold, anyway, took it in for a service yesterday and the report came back and said inlet manifold blowing past swirl flaps would require new manifold, I know this isn't a cheap job, but basically my query is this:-
The car has 43,888 on the clock, I took possession of the vehicle at 37,660, put a blanking plate in at 40,000 and the gearbox died at 41,000 :( so having had that replaced along with the clutch and DMF, vx are now saying new manifold, surely though the blanking plate is gonna stop more rubbish gettin in? As the only damage that could be caused is by the stuff already in there....

Checked swirl bar etc and it just needs a good clean, they all move in the correct direction all at the same time, I've had a friend look too, he had his manifold done about a month ago.

So yeah, any ideas on where to go from here?

The blanking plate will stop more soot getting into the manifold, but the damage has been done in the 40K miles prior to you fitting the plate.

If the swirl bar is on, and the EML is not coming on, then keep driving it until something goes wrong. If there is oil and soot around the bearings, then failure is inevitable.

Nothing in the way of oil around the bearings on top.. Although the eml came on about 20 miles after putting the blanking plate in

I bought my car with 60,000 miles on it. I blanked off the EGR straight away and about 20,000 miles later, the inlet manifold failed. So if the damage was already done, fitting a blank will not stop it failing. Now, if you fit a new manifold, I'd be fairly confident that fitting a blank from new would stop it failing in the future.

With regards to looking after the gearbox, just try and drive more smoothly, and check this thread out too:

Might just save a couple months of pay and get it changed for peace of mind and obviously keep the blanking plate in
