Any drive a Mondeo TDDi?
A friend of mine has just bought a 2002 TDDi Mondeo, low mileage, mint condition etc. but is rather upset to find that according to the trip computer
economy is hardly better than his previous V6 Ghia. A 100mile mix of urban and fastish dual carriageway dirving this week shows just over 30mpg. The
TDCi hire cars I have driven seem difficult to get below 50mpg! Is it broken or is it just a legacy of the mechanical injection?

I can back up the fact that our Focus TDCi gives about 50mpg on a run.
The TDDi mondeo should give about 45mpg IIRC.

It must be broken.
My very elderly 148K miles Audi 1.9tdi does 42-45ish to the gallon. That's hammering it all the time.

I drive a TDCi. Although the computer shows the vehicle to be averaging around 50mpg, I consistently achieve about 42mpg (driven in anger) I
wouldn't trust the trip computer as far as I could throw it. Tell him to work out the fuel consumption in the proper way, then he will be in no
doubt.

Thanks chaps, I told him to work it out properly, but he's just comming to terms with the loss of his V6 after a woman in a Ka decided to turn
into the side of him...
At least she had the decency to kill it just before it went to the spray shop...

A4 TDI
I couldn't agree more, I've had an 02-reg A4 TDI 130 from new (4 years old tomorrow) and the Trip2 computer says it has done 50.4mpg over
the 72,700 miles it has covered. The Trip1 which resets each journey seems to agree on average, but looking through the company mileage sheets, it is
averaging more like 44.5mpg!
As an aside, the variable service intervals on my car mean that it is serviced roughly every 23,000 miles (excess I know), and the difference between
the mpg before and after the service is staggering. It's going in next Tuesday for a major service including cambelt and is only averaging 40
at the moment, but acording to the mileage records, it should be up in the high 50's after the service.

driving like an absolute maniac i once managed to get my chipped 1.9tdi down to 31mpg on a 40+ ile journey (shortie can vouch for that!), i then got
pulled over by the law 1 mile from home (once they'd caught up with me) i normally get 44-45 based on the last 8000 miles of ownership and
have had 52mpg on a decent run.

OUCH!!! Bet he was annoyed at that. It was different colours though
It should do over 40mpg. Id get it checked out. They are prone to injector faults.
My passat Tdi coming up for 100k does about 45-50 ave with me booting it.

Ive got a TDDI Mondeo. Driven (extremely) carefully it will return 55 mpg but I usually only see 30 ish. Its all down to your right foot. The tdci
is a huge improvement Im told.

my 1.9 laguna is a bit disappointing - it does about 42-44 on a run and can just touch 50 if im really careful..... a mates 2.2 litre mondeo st diesel
does around 48mpg and can do over 50 with little effort - and thats 155hp! mines a lowly 120....

Focus TDDi...55 steady Eddie on motorway, 50 mix of motorway and town, 45 around town short journeys. Anthing under 40 does not sound good unless
thrashing all the time...

Has the injection system got a hot wire mass airflow sensor if so that would be the prime suspect.

I don't know to be honest, I've not looked under the bonnet yet! I know these strange beasts have an electronicaly controlled mechanical
injection pump though and fly by wire throttle etc.
