Having replaced the blend motors and o-rings on my last P38 at about 75K miles and the new P38 having covered only 40K miles I was hoping it was a job I wouldn't have to face again in the near future.

Looking through the comprehensive history that came with the car it now looks like it maybe even further away Because they were replaced in April 2010 when it had covered only 30K miles!! I know that the blend motors are not the most robust bits of kit but that really is not very good for a 50K plus motor.

They also put it into a Landy Indy who robbed them of £741.00 of their hard earned

RR's don't you just luv em.

My local Indy has just quoted me £786.62 to replace blend motors and O rings. Needless to say, I won't be going there.

If the blend motors were fitted then left to their own devises to cycle that could be the problem. They should be calibrated after fitting.

According to the invoice their £740 included calibration with testbook. Talking to my local Indy several years ago he told me he had had P38's with under 80k miles coming back for a second time to have them replaced I thought he was pulling my plonker at the time, he obviously wasn't!!

If the blend flaps are tight, this can put excessive strain on the motors..which are flimsy and underpowered at best. Result......premature motor failure.

Spot on - I wonder how many Blend packs have been changed worldwide on P38's only to fail again cos the distribution flap is tight in the heater box ? See the info on RR.net for my info on how to free them up enough to make them work properly....

Is it possible for them to partial fail? On Thursday when i was driving back from Heathrow I noticed that it started to get cold. Did some tests and set the temp on both sides to Hi. My side was delivering no hot air at all. The passenger side was giving out warm air. Changing the settings to Lo changed the passenger side to cold air so there must be some movement in the motor. No idea if the passenger side has been troubled before but my side always worked fine until Thursday and that was after 150 miles of a 170 mile trip. The cheque book symbol came on a few minutes after I started the tests. Does the new Nanocom allow you to calibrate the motors?

The heater box shrinks when cold,this is when the blend motors stuggle to achieve the desired movements.It seems the distribution flap is worst in this respect.Calibration wont help,freeing off the flap will.
