Giving Up Smoking - rogerb

My one-year-old Focus tdi has always smoked heavily when accelerating and had a rather excessive thirst.

I have been advised, by a producer of ECU chips, that there is a known problem with some Focus tdi's which has been traced to the Exhaust Gas Recirculation valve, and that some dealers get around the problem by "simply disconnecting the pipe at the valve".

Do you or your readers have any experience of this, or advice to offer, please?
(I am planning to have it diagnostically tested at my Ford dealer, as advised by the tuner

Not an uncommon problem on Ford Diesels. Yes you can simply disconnect the EGR valve. Doesn't seem to have any adverse affect on the running but should the powers-that-be decide to test diesel exhaust emissions differently (a "cat" test) this may mean that rectification of the problem may be neccessary. Replacement of the valve does not seem to help, it appears to be a problem with the management system as far as I can gather.

re: disconnecting the egr valve

Is this a fairly simple procedure, and easily 'reversible', should the need arise?

Thanks!

Yes, just disconnect the vacuum pipe from the valve and plug it. If this is the cause of your woes the improvement ill be instantly noticeable!

Thanks.
Is it possible/probable that such a 'mod' would affect consumption as well as smoke?
Or are there other possible adjustments to the Ford tdi engine which might help? ( I imagine that most settings are 'hard-wired' into the ECU these days?)

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.

Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.

Real MPG

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
