Guys,

I have the IS250 petrol auto, I find the engine is really really ticky, I have checked the oil, however I think this may be a fuel pump type of tick than a tappet noise. Anyone out there have the same noise from theirs?

Think the ticking is from the fuel injection system (pump?). Only noticed it on mine when the bonnet is up and of course the engine running :D

... it's your high pressure fuel injectors (the price you pay for good fuel economy) :)

good fuel economy?

Came back from Leeds yesterday, around 220 miles ....averaged 33 mpg @ average speed of 73 mph :ohmy:

Good economy? Well, the ticking noise is caused by the extremely high pressure in the fuel injectors. The pressure assists the optimisation of the fuel charge and its spray patternisation, minimising fuel waste, and thereby supporting fuel efficiency.

My 250 SE-L Auto has never shown below 30 mpg over a tank, and has regularly given me 38~40 on a run; I'd suggest after my previous car that that's good economy :)

I had the noise from the instrument panel too...it sounded like a rachett noise when the dials move around quickly at startup. I had the instrument panel replaced under warranty.

Take it in a let the dealership have a look :)

How many miles had you done before the panel was changed?

it had just ovet15.7k on the Clock before they changed the instrument panel(it's been written in the service history book)although it did start making a noise about 600 mile before.

I did wonder whether they would make a note of it, or allow you to "fudge" the mileage!
