Ok so I have had problems with my 06 plate Focus diesel for a while now.

After several mysterious limps home on longish journeys, and each time the garage not finding anything that they thought was a problem, something weird happened.

I broke down. One night after getting to within 5 miles of my house, my car was losing power and starting to go into limp home mode. Having been entirely frustrated I just decided "hey I'm close to home what the hell" and just kept sticking my foot down. After a 5 minute fight my car was having none of it and just kept getting slower and slower.

Eventually the engine cut out completely, power steering went.... the lot! So I just about heaved it up onto the hard shoulder, called the tow truck and waited patiently. So after an hour the tow truck showed up, and he actually just about managed to get the car started again. So I drove to the nearest garage, leaving my car there for them to look at the next day. On the drive back to my house he mentioned that he recently picked up a lady passat owner with much the same problem.

He then gave me the best piece of advice I have seen yet, KEEP YOUR FUEL TOPPED UP. Since then I have been religiously topping up when my fuel gets to about a 1/3 of a tank if I am going on a motorway longer than 30 minutes. I have had no problems with loss of power since then.

I had a final test of this today, I was travelling from Bournemouth to Portsmouth and was on around 1/4 of a tank... so for once I thought I would risk it. I got as far as Southampton and the car started losing power. I immediately turned off the motorway found the nearest fuel station and filled up. I then drove to Portsmouth and then back to Bournemouth with absolutely no problems, not even the odd fuel blip.

So there you have it folks, if you have a problem with a diesel Focus going into limp home mode on motorway journeys, maybe its worth taking note of how much fuel you have on board, and if it happens when its continually below 1/3, try keeping your tank topped up and see if it solves the problem.

Could be the gauge is faulty or weak fuel pump you still have a problem it will not go away

Many modern diesel cars have a feature which will reduce engine power when the fuel in the tank drops below a certain level. This is designed to alert the driver to the fact his fuel is low and to top it up before expensive damage occurs to the high pressure fuel pump. A bit over-zealous perhaps, but you must remember that modern diesel fuel pumps are built to very high tolerences, and they are lubricated by the fuel itself. Common rail diesel systems such as the TDCi must achieve a pressure of 10,000kpa (1,000bar or 14,500psi) in the common fuel rail before the engine will be allowed to start.

Sorry but to me this is plain crap. I always leave my clio dCi right down to when the light goes on and stays on, then refill. And it's still a common rail with 1350 bars injection pressure. If it is indeed related to the fuel level going low, I would inspect the fuel tank and see if it is full of debris which might be clogging fuel delivery pipes - and eventually clog the diesel filter.

My father has a mk 1 1.8 TDCi from new and the list of faults in a mere 25,000 miles has been flabbergasting...loss of power which after two years fighting with my local and only Ford dealer turned out to be a broken wire from the MAF sensor to the accelerator pedal (PCM), - problem returned after a few months even though wire was replaced - DMF failure (thank God it was just a month before the warranty expired), water pump, auxiliary drive belt and idler failure, fuel gauge which overshoots and stops on half when turning off whenever the fuel tank is over half-full, gear selector nut falling loose, clunking noise from RHS front suspension (probably a wishbone bush or shock)... Whenever I hear someone rave about how reliable these vars are my stomach retorts in disgust.

We've got a 2004 Focus C-Max 2.0 TDCi. My wife warned me not to buy it. Reliability has been wretched. Just a few of the faults we have experienced - complete engine management failure (in garage for 6 weeks!), air con, alternator, electric windows, clock on radio, reversing lights, fuel sender unit replacement.

It got so bad that the company providing breakdown cover cancelled our membership because it broke down so often.

I am currently waiting for the engine to blow up as it tries to shake itself apart at idle and the engine management warning light sometimes comes on ....

Shame really that it is such a comfortable, powerful and nice handling car ....

well done stuart. i would still sugest the tank needs checking or the calibration of the gauge.
Stan the man who thinks reduced engine power on a low fuel tank is CARP is talking balderdash. Many new cars have this facility now and my Jaguar used to switch the aircon off when the fuel was in the red and when it got too low it would reduce to 3 cylinders! and it also warns you in the handbook that this is indeed designed in to save fuel and get you to a station

A six cylinder car reduces to three cylinders when low on fuel I don't believe it.

Andy, 4 cyl Diesel and it states it in the handbook that it will do exactly that! its weird the first time till you know why
