Hi Guys

Hoping someone can help me with the issues I am having with my car as the dealership keeps telling me there is nothing wrong.

The car has travelled 21k and the problems have been evident since about 15k and have gradually got worse. The car would thump into gear when cold, but then it started to loose power as I was driving it.

At this point I thought I may have picked up a bad tank of fuel so I made the decision get the ford dealership to inspect my fuel and fuel pressures. They didn't believe that it was a fuel issue but informed me that the fuel was a little bit dirty so I decided to get the tank and fuel system cleaned aswell running carbon cleaner through the engine.

Unfortunanetly this did not fix the problem and the car has now developed even more issues, it drops down gear as soon as you take your foot of the pedal, the tacho is very erractic in its operation almost like it is getting a faulty signal and at times the car struggle to produce power almost like there is blockage somewhere.

Also when excellerating upto highway speeds and the gearbox is changing up through the gears there is a lag between gears almost like you are taking your foot off and putting it back on again.

I have had a mate drive it just to get a second oppinion and he agreed that there is a problem so I am at a loss how to fix it.

It has been back to the dealer 4 times and 4 times they have told me there is nothing wrong. It is not registering any fault codes, so they believe that there is nothing wrong with it.

It never plays up when they drive it, but they always drive it with the climate control off so maybe it has something to do with that.

Hoping someone can help identify what the problem cause it is driving me crazy.

Have you demonstrated the issue to a tech/foreman?

Have you demonstrated the issue to a tech/foreman?

Each time I have been back I have taken either the road tester or manager with me to show them what it is doing. I have even driven a different car to compare the differences between mine and theirs.

I believe that the reason they can't pick the issue is 1, they don't take it for a long enough drive 2, they drive so many that they all feel the same to drive and 3, they are not able to drive it on the same road as I do so they can not replicate the loads and conditions that I have.

So has the car ever faulted with them in it?

And is it 5 or 6 speed

It's a 6 speed auto. The car has only faulted once or twice with them in it but not bad enough for them to be concerned. I want them check sensors and switches manually instead of relying on the computers.

It's going back tomorrow for a cold start test so hopefully they will find an issue that they can work with.

Thing is... 99% of the time if its a sensor issue there will be a code... Cold start test is a good idea... I still dont really understand the issue your having as your post was a bit confusing but harsh engagement when cold can be a sign of incorrect oil level, which is critical for these gearboxes

Cold start didn't give them any idea as to what might be causing the issue as it didn't play up. Dealer suggested I take it to another dealer for a second oppinion which I have done. Second dealer adjusted the fuel settings and made changes to the way the gearbox changes and how it changes. On innitial test drive car seemed to drive a lot better, but I guess time will tell to see if it has removed the harsh changing when cold.

Changed how it shifts hey... Hmmmm

O_o

Some things to try as possibles and the tacho fiddling around starts to head towards a "maybe electrical" thing.

Disconnect the battery and make sure it is showing 12.4 - 12.5 volts.

Re-connect the battery and test the voltage across the car. Put the tester lead on the positive to the battery and the earth lead on the engine. Should show the same voltage ( well ... within 0.05 to 0.1 volt). Fords can be buggers for poor earthing - despite all assurances to the contrary.
