EP in a manual car

[nomis64]

Sorry, read a sticky after initial post so its a R75 Contemporary 1.8T manual tourer

Hi
I'm more used to old mgb's, so error codes are a mystery to me! On the forum the mentions of an EP code seem to refer to auto boxes, but we are currently looking after my late Father in Laws 1.8 turbo manual tourer. It seems to run well, pulls as hard on acceleration as I would expect for nearly 2 tonnes and 160hp. I cant see much water in the Plenum despite last nights downpour. Any suggestions where to start sorting out the EP that is showing in the dash?

By now on a classic MG forum someone would at least have cracked a joke, or asked for clarification, if not given some sage advice. 119 views and not a peep...

Just a though - like I said, I know nowt about error codes without reading it up...it transpires about 7 years ago the instrument cluster was replaced when the original failed...might it be the 2nd hand replacement sourced came from an automatic car, and it thinks the gear box is all wonky and it wants to put it in limp mode but it cannot because its a manual?

I’m surprised that you’ve had no replies so far, as there are lots of knowledgeable people here. Unfortunately, I’m not one of them…at least, not as far as error codes are concerned.

Hopefully you’ll get a helpful response soon.

When the replacement cluster was fitted, it should've been coded to the car. This tells the cluster whether it is fitted to an automatic or manual car. Does the cluster have a gear display like this one (the big letter P on the screen near the bottom of the cluster)?

The gear display should only be active on clusters coded for an automatic car. Has the replacement cluster always had this EP fault, or is it a recent thing?

The factory manuals are available here: https://the75andztclub.co.uk/forum/s...87&postcount=8

The "system description and operation" manual gives a little bit of info, stating that EP is displayed when an automatic gearbox fault is detected (as you already know) but I couldn't quickly see anything more helpful than that. It might be worth a more careful look through though.

The best place to start would probably to get it plugged into T4 diagnostics and see what error codes are stored or check the coding configuration of the cluster. There's an MG Rover specialist called D&D Vehicle Services in Somercotes near Alfreton, they might have a T4 machine.

Or if you fancy trying to have a go at reading the codes yourself, download a copy of TOAF onto a laptop and buy a compatible cable.

Or buy a P-Scan

Sorry, I don't have any personal experience of this problem so don't have any specific info, but I hope this helps a bit.

I have TOAF and a cable, if you want to pop round and try it.

It would be very much a learning experience though, as I haven’t really done anything with it yet.

Bit of a strange one, as the normal error for an incorrectly matched IPK would be ERR - sure it's not that?

Mind you, perhaps as said, it is an automatic IPK and can't find the autobox therefore the EP appears.

Toaf is very easy to use, but back-up the module first.

Regards

Not sure how to do this, but this is a pic with "err" and "EP" to my eyes!

Would it be better on a dry day? Just took the car round the CMGG shakedown run and it didn't miss a beat...

Looks very much like mismatched clocks 🤔
