My initial idea was trying to refurbush my old assembly with the gaskets from Rimmer, saving some waste. However, the repair kit is on backorder, so I wouldn't be able to do that soon anyway. Ordered the full assembly, as you said the motor is not available seperately. My main priority is getting the car up and running safely again, after that I can look at my old assembly and see if it is worth refurbishing. Thank you once again for all your help Simon! |

Did you run a live data test while driving, that should have shown which wheel was causing your issue.

P1472 results when the power actuator cannot drive the valve linkage properly. It may be electrically faulty or the linkage may be broken. Club member Stocktake is your man for these and the codes are separate to your idle control problem. They will affect engine performance though. Simon

The MG Rover specialist I went to did the T4 diagnostics with the car stationary. I explained to them my fear of an ABS problem and wanting to know which wheel was causing issues, so it would be a bit sad if I just paid €45 for a diagnostic session that provided no new information. Afterwards they also told me they can only diagnose ABS issues when the light is on, which based on your question also does not seem to be the complete truth? When you say that they should have done a live data test, does that mean that the ABS issues that cause a brake pedal judder braking at low speed do not produce error codes that are stored? Quote:
I see I got a bit too excited there with the error codes hahaha. On the forum I read a lot of low power symptoms associated with the P1470 and P1472 error codes which I do not have, placing them in the context of the VIS motors. Also, my mileage seems pretty decent (~9,75 km per litre on average), making the codes a bit peculiar. Do have a nasty rattle though, but listening with a stethoscope did not seem to indicate that this came from the inlet manifold (I rather thought it was one of the auxillary pulleys). I'll keep an eye on it, and I removed my older message as to prevent confusion! |

Noberror codes will be stored when you have the pedal judder, this is why you need to drive the car slowly and see which wheel sensor is fluctuating when driving, chances are it will be one of the rear wheels (normally a bearing)

I had to replace my right rear back plate this year, it was rotten to the point that the handbrake shoe was not fixed in the backplate anymore. I guess I did not clean up the surrounding area after, so if the garage still does not know how to test what wheel is causing up with the T4 I at least have a good starting point for the cleaning. |

Replaced the stepper motor assembly, which seemed to cure my problem at first. However, after having parked it in the sun after a day of driving, starting the car the problem came right back: rpm's shooting to 3000, not coming done. Ordered the repair kit from Rimmers. It's currently backordered, but I'll update this post when I get it in the car. Fingers crossed! |
