Annoyingly my cars started erroring with the Workshop P error message

I’m aware there’s the bypass kit which looks fairly fiddly but do-able, however I don’t have the message all the time, is there anything I can do other than fitting the bypass kit?

Think mines a DQ250? 2016 190ps 6speed

I had a quick look and the plastic bits are white on mine

Anyone?

Not going to be much help, here, as the only fix I've heard of is the bypass kit.

However, mine has been doing it for 2 years, on and off, and I just ignore it.

I did read of a suggestion to move the lever back and foward from P to D 50 times

to "unstick" the faulty switch, but it didn't work for me.

Sorry.

Hi. I had this intermittently and just bought the bypass kit from aliexpress. Cost about £30 and took about an hour to install. A bit fiddly but not too bad.

Check carefully the part number, as there are two for the white top gearbox where the part number is the same except for one doesnt have an A at the end. Im pretty sure the one without A is the one you need. This is the exact one I bought: https://www.aliexpress.com/item/1005009808126126.html

Have a play with the plugs before you install so you can work out how they release, and get yourself some decent trim removal tools. You will also need Torx 10 and Torx 8 screwdrivers (I think)

From memory this was the process:

• Ignition on and shift to N. Ignition off as much as you can.

• Remove trim from around gear stick (The trim with the buttons including parking brake etc)

• Push out from this trim the small surround for the gear stick

• Disconnect all wires from these trims and wiggle the larger trim off to give more access, then pull the small trim up until the leather gaiter is inside out.

• Pull up mounting for 12v socket/USB and disconnect all wires (This was quite tricky as every plug seems to have a different catch system)

• undo 2x torx 10 screws holding in "ashtray" and remove. Undo the interior light wire from this or I just tucked it to one side and left it hanging.

• I had to rip out some bits of foam from around the top of the gearbox for access. I just placed these back in place once done.

• Using a long thing screwdriver push the blue tab on the connector just in front on the left of the gearbox top to release the original plug.

• Then contort fingers in about 20 directions to connect the new plug and the existing into the bypass kit.

• Undo 3x Torx 8 screws on top of the white plastic and fit switch using supplied longer screws.

• Loosen off the two screws in the slider slots on the new switch

• Shift to P

• Pull switch hard against the gearstick shaft and tighten up the two slider screws

• Move from N to P a couple of times to check operation. You should hear the relay clicking in the fusebox.

• DON'T be tempted to turn the ignition on, as you will get a whole host of errors as all the buttons are disconnected. They clear once all reconnected but did make me panic a bit!

• Refit all the trim panels in the reverse order of above making sure wires are tucked out the way of the trim clips etc.

• Start car and operate park brake on and off a few times to clear any errors.

• Shift to P and make sure its happy!

Unfortunately I didnt take any pictures as I was doing it. I might do whenever I work on the car in future so that I can post here to help others.

Also while you are in there might be worth installing the start stop memory module. Well worth it in my opinion.

Excellent thank you, it’s been behaving correctly recently but it’s clearly on its way out, job for warmer months
