I was around that figure with a manual saloon, auto tourer is a different beast. Nearer 35 in town but can still get 50 on a run.

PS the diesel Tourer has now done 153K and is as smooth (remapped by Big Russ) as when I bought it 9 years ago.
A quote from a government consultation. Green paper likely very shortly:

Tackling tampering
We will create new offences for tampering with a system, part or component of a vehicle intended or adapted to be used on a road. This will enable us to address existing gaps in the legislation, ensuring cleaner and safer vehicles. We will also create new offences for tampering with non-road mobile machinery (NRMM) and for advertising ‘tampering’ services or products.

This will strengthen our ability to enforce compliance in this area.

We are aware that the Law Commissions in both their first and third consultations on automated vehicles have considered tampering. We await their final recommendations and would welcome views on our proposals, as follows.

Specifically, we would look to create:

a specific offence for supplying, installing and/or advertising, a ‘tampering product’ for a vehicle or NRMM – this would apply where a principal effect of the product is to bypass, defeat, reduce the effectiveness of or render inoperative a system, part or component (the product may be a physical part or component, hardware and/or software)
a specific offence for removing, reducing the effectiveness of, or rendering inoperative a system, part or component for a vehicle/NRMM and advertising such services
a specific offence for allowing for use or providing a vehicle or NRMM that has had the operations described in the previous 2 points performed on it
a new power to require economic operators to provide information, where a service/product they have supplied amounts to or enables ‘tampering’ with a vehicle or NRMM – this would apply in any of the above senses and include requirements to provide relevant information on the quantities of products sold or modified

There you go then going forward it's best to just clean the EGR, so all those after market EGR by pass products sold on ebay sellers will get stuck with them, start stocking up on swarfega, cheep tooth brushes, car cleaner, rags, maybe purchase an EGR to work on to clean and always have have a spare to change out once a year.


Cleaning is not tampering

PS maybe best to keep our mods to our selves in the future, you never know who may dob you in.

There's no performance advantage with a egr bypass, and if the new legislation does come into force the best way is to keep the original, clean it then stealthily disable it

The problem with the EGR valves is that they can take a long time to close if they're not in as new condition which is actually worse for emissions and fuel economy.

If you take 20 cars all with similar mileage and working egr, rev them to 3k then take you foot off the accelerator and then time how long it takes for the valve to shut you will get 20 different results.
From a few seconds (good) to in the worst cases over a minute.
Whoever thought this was a reliable way to control emissions really needed their head examined.
If you disable the EGR it has no negative effect on the emissions for Mot purposes.

I marvel at all these cars which do 50mpg, where mine (driven gently, which is all I do most of the time these days) returns 42-43, and always has. I drive almost exclusively in the countryside, and have owned the car for 12 years/120,000 miles now, during which the mpg hasn't changed noticably.


160 remap by PhilT4 didn't produce any noticable effect - the car is the 131 model.


It's been T4'd several times, and given a clean bill of health - and is maintained by a Rover specialist.


Anybody got any ideas


PS mixed short and long distance driving, but for the last couple of weeks I had a lot of motorway to do, so reset the mpg meter - it only rose to 44.1.

If it is an auto then pretty much par for the course from what I've seen.

42-43mpg is perfectly good. All these people that get over 50mpg around town aren't doing brim to brim tests, the engine is old and the car is heavy. You won't really notice much from a 131ps stock tune to the "160" map. A stock 131ps car runs about 120bhp on a calibrated dyno. A "160" mapped car runs about 130bhp.

My Alpina D3 managed around 43mpg around town and touches 57mpg on a run, but this is with a 6 speed gearbox.

I saw a report once about people who find ways to get more mpg. Their big idea was to not let them go above 2000 revs in any gear.

My manual achieved 50+mph on a run. I've had several autos which on shorter rural trips manage 36-37ish, on a decent run 42-44.
