Default Anyone close to Manchester that can help with an EP problem?

Just started my 04 2.5 Petrol Connie Auto only to get the dreaded EP on the display.

I've disconnected the battery for 15 mins but still the same, I've also checked the plenum and it's bone dry.

Haven't had any gearbox judders to suggest its the 2/4 solenoid, although it judders now, is that just due to the emergency mode or could that suggest the solenoid needs replacing?

Is there anything else I can do to either eliminate a problem or narrow it down myself?

If not as the header suggest is there anyone close to Manchester who could have a look and maybe help?

Cheers

Paul

I would go to Big Russ at Liversedge a maestro on our cars and a T4 operator - only 35 miles or so from you - drop him a PM.

You're right Russ is a maestro and a nice guy but as I'm in Emergency Mode I cant get over to him ( even if its only 35 miles away!!!)The M62 is not the ideal road to be schlepping at 10 mph!!!!

I really need someone one in the know to come over to me to check it out and determine the fault in the first instance.

Iíve known Russ travel in the past but no idea how far. Iíd ask him, but of course pay him for the travel and time if he does.

The only guy I use for none heavy work

Hello Paul,

Strange as it may seem, the 'EP' indication does not necessarily mean a gearbox fault. It could be CAN bus communication problems with the automatic transmission ECU.

To rule this out, are your tachometer, temperature gauge, PRNDL display, check engine lamp and traction control (if fitted) displaying normally in the instrument binnacle?

Hi Simon

Funnily enough the tacho and temp display weren't working, however I've just connected TOAF, scanned the engine then cleared all DTC's and the car is back to normal.

The next challenge, of course, is to determine what caused the fault in the first place, and try to prevent it happening again.

It sounds as if there could be a potential problem in the CAN bus

Cheers

Paul

The CAN bus communication between the Engine Control Module and Instrument Pack has an intermittent fault [Source: RAVE].

It's good to know it's not the gearbox eh?

Oh yes!! Now if you've just got that from RAVE I'm going to have a good look at the disk as it's actually in my laptop anyway ( think it spends most of its life in there!!!)

Does the pertinent wiring loom pass near the N/S headlight? I seem to remember many years ago that a similar problem was caused by the loom chaffing in that area. I can't be certain as my memory is worse than a goldfish.

Yep it does Steve, close to the bumper and then back down the wing. I've taken the wheel arch liner out as well as the Air Filter for a proper inspection but no fault found yet.

This could be a long saga I think!!!
