I like your thinking Mr K. (and agree with you logic).
Hi Craig,
I will try and explain what I understand the garage did to answer you questions, and I would be happy to ship it to you, I may be in the US next month (if this is the source of the problem).
I would like to ask you how they...
Voicey/Maverick, thank you this is very helpful and makes this a far more complicated job than I had understood. Voicey I would love to pick your brain and see how I best resolve this minor but annoying issue!
Craig, Thank you also, let me explain a little more to answer your question.
The...
I have a small issue on my 4200 CC, where the F1 pump does not prime when the car is unlocked (whereas it previously did!).
We have hopefully traced the source of this problem to the Transmission Control Unit (TCU) which is not sending the signal to the F1 pump to prime (whirring sound on...
Hi David,
Apologise for the delayed reply, I have been away for the past week and just catching up today.
I also believe my problem lies in the drivers door lock for a couple of reasons, firstly because the F1 pump and relay obviously work when the engine is running, but not when the car is...
Interesting as I had a slightly similar experience some days before realising the F1 pump noise was gone. I had parked on a very slight slope with handbrake on and in First gear. but when I came to start the car 10 minutes later, it would not start on turning the key and the brake pedal felt...
I certainly used to hear the whirring on unlocking, from outside the car, but will get under the car and see if see/ hear anything odd. On turning on the ignition, I hear various noises (with aircon fan turned off) but I cannot identify if these are from behind me (from F1 Pump). I may be...
Catman - you can keep your hat :-) You were right - I changed out the F1 Relay but it did not make any difference.
However, I definitely do not hear the F1 pump whirring when the car is unlocked/door opened (although I used to hear it!) but the car drives normally having gone for a spin after...
Thanks Catman.
Having left the car for 24 hrs, very late last night I listened for the F1 pump noise, but did NOT hear the whirring, (I did not have the chance to start the engine) so today I will change the relay and see if I hear anything.
And then take it for a little spin to check the...
Conaero/Chris - Thank you both for the prompt feedback, this is extremely helpful and a relief, especially as if this means limited expense!
I will investigate further in a quiet spot, but the "seed has been planted" to changing over the F! pump, especially having seen the fantastic "How to"...
