EPS & ASR fault, diagnostic shows C1638 & C1135- drivable and intermittent, resolved by ignition off and key out

[pugnacious]

Evening all, first time posting. Apologies if this has been covered in another post, a search didn't reveal much.

1 week old owner of a 2015 "Style" (1.2 VTI) from a dealer. Test drove ok, documentation was ok, a basic OBD scan (all I had with me) was ok, so we bought it.

Driving home and the EPS light illuminated, infotainment screen indicated an EPS & ASR fault. Steering was still possible, but unpowered. I pulled over, killed the engine- nothing obvious but noted that ignition off, key out cleared the issue. I phoned the supplying dealer then and there, and they promised to honour the warranty; all I needed to do was get it fixed and they'd foot the bill.

The fault persists but is intermittent. Of the 6 days I've owned it, for 4 out of these the fault appeared and it's been driven every day. The quick fix still works.

There's an independent Pug/Citroen specialist nearby so I dropped it in there for diagnostics today. 2 codes present
-C1638 (estimation of steering wheel angle- consistency)
-C1135 (steering wheel angle sensor signal from s.w angle estimator or s.w controls- internal)

They cleared these, recalibrated the angle sensor, checked for wiring faults. They also warned me that if it occurred again their recommendation would be for a new EPS/rack unit to be fitted, as these codes indicate an impending failure in that area. I understand that on the 208 rack and EPS etc are all amalgamated.

The prices from Peugeot are eye-watering...he showed me this on their ordering platform: £1900. Yikes With labour involved, that would mean about £2500. That's non-optimal.

I have the choice of challenging the dealer on their promise to repair this, or reject the car. Probably the latter I think.

But I wondered about 2 questions in my mind that I hoped someone could maybe answer:

1)Is this a common thing? I had hoped to leave the EPS issues behind with my last 207
2)Is a new rack/EPS unit from Peugeot my only option? Are there any refurb or similar manufacturers out there, to maybe try and lower the cost?

All the best

Oh, and I should add: the fault occurred again on the way back from the indy

Don't you think that the problems you have identified is probably the reason why the previous owner sold the car to the dealer! .
Take it back if you can, or get it fixed at someone else's expense.
