First off, apologies for posting here if it's not allowed, I'm a new member and can't post in the diagnosis forum.

Bought the 8 a few weeks ago. The previous owner had it in storage for 6 or so years. While in storage, the rear left tyre had a nail in it and thus was flat.

Previous owner wanted to sell so drove it 70 or so miles from storage to his place (presumably with the tyre filled up. It's getting replaced anyway because it's 14 years old).

Enter me. Bought the car off him, filled the tyres up and drove home.

First thing I did was plug the tyres up, they reliably hold pressure now. Filled to 32 psi and the lights disappeared for a moment on restart and shortly came back
(without pressing brakes, within 1-10 second of startup. Now instant however). Drove 17 miles with it filled up to let the computer do its thing and maybe it would solve itself but life is never that easy.

I checked both the abs sensors or is it wheel speed sensors, on the rear side. Resistance read 1.336 and 1.339 ohms so it seemed fine to me. Disconnecting them threw different codes too so I doubt that's the culprit.

I've gone through most of the usual suspects recommended.
Resetting by turning the wheel both ways on ignition
Brake lights work
ABS, stop, DCS, cabin DCS fuses are fine
No led brake lights

Now to the main part, the code that it throws
C1250 - Left rear inlet valve coil circuit failure

If anyone has any ideas, I'd love to hear it, because I haven't a clue what that is.

UPDATE: I've installed the ABS module I've got off eBay. I've only bought it according to the part number I saw on the pump on my car and the eBay one as well as the same 231PS I see in the description. Forgot to compare the module part numbers.

First plugged in the ebay ABS module and Pump in together with the connector without removing the old one to check if it works, all codes went off.

Only replaced the module itself and kept the same pump and that threw off the TCS and DCS off blinking. Followed the reset procedure of turning steering wheel left and then right while ignition on and then restart the car. Lights went off and all is well now. Car is finally MOT ready. Didn't need any programming which was surprising.
